Ficus carica

Botanical Name: Ficus carica
Family:    Moraceae
Tribe:    Ficeae
Genus:    Ficus
Subgenus:Ficus
Species:    F. carica
Kingdom:    Plantae
Order:    Rosales

Common Name : Common fig  or simply  Fig

Habitat: Ficus carica is  native to the Middle East and western Asia, it has been sought out and cultivated since ancient times, and is now widely grown throughout the temperate world, both for its fruit and as an ornamental plant.

Description:
Ficus carica is a gynodioecious (functionally dioecious),deciduous tree or large shrub, growing to a height of  10.00 to 20.00 feet and Spread  10.00 to 20.00 feet with smooth white bark. Its fragrant leaves are 12–25 centimetres (4.7–9.8 in) long and 10–18 centimetres (3.9–7.1 in) across, and deeply lobed with three or five lobes. The complex inflorescence consists of a hollow fleshy structure called the syconium, which is lined with numerous unisexual flowers. The flower itself is not visible outwardly, as it blooms inside the infructescence. Although commonly referred to as a fruit, the fig is actually the infructescence or scion of the tree, known as a false fruit or multiple fruit, in which the flowers and seeds are borne. It is a hollow-ended stem containing many flowers. The small orifice (ostiole) visible on the middle of the fruit is a narrow passage, which allows the specialized fig wasp Blastophaga psenes to enter the fruit and pollinate the flower, whereafter the fruit grows seeds.  Fig pollination and fig fruit.

The edible fruit consists of the mature syconium containing numerous one-seeded fruits (druplets). The fruit is 3–5 centimetres (1.2–2.0 in) long, with a green skin, sometimes ripening towards purple or brown. Ficus carica has milky sap (laticifer). The sap of the fig’s green parts is an irritant to human skin.

Cultivation:
The common fig is grown for its edible fruit throughout the temperate world. It is also grown as an ornamental tree, and the cultivar ‘Brown Turkey’ has gained the Royal Horticultural Society‘s Award of Garden Merit.

Figs can be found in continental climates with hot summers as far north as Hungary and Moravia, and can be harvested up to four times per year. Thousands of cultivars, most named, have been developed as human migration brought the fig to many places outside its natural range.

Two crops of figs are potentially produced each year. The first or breba crop develops in the spring on last year’s shoot growth. In contrast, the main fig crop develops on the current year’s shoot growth and ripens in the late summer or fall. The main crop is generally superior in both quantity and quality to the breba crop. However, some cultivars produce good breba crops (e.g., ‘Black Mission’, ‘Croisic’, and ‘Ventura’).

There are basically three types of edible figs:
*Persistent (or common) figs have all female flowers that do not need pollination for fruiting; the fruit can develop through parthenocarpic means. This is a popular horticulture fig for home gardeners. Dottato (Kadota), Black Mission, Brown Turkey, Brunswick, and Celeste are some representative cultivars.

*Caducous (or Smyrna) figs require cross pollination by the fig wasp with pollen from caprifigs for the fruit to mature. If not pollinated the immature fruits drop. Some cultivars are Smyrne (Lob Incir in Turkey) – (Calimyrna in the Great Central Valley USA), Marabout, Inchàrio, and Zidi.

*Intermediate (or San Pedro) figs set an unpollinated breba crop, but need pollination for the later main crop. Examples are Lampeira, King, and San Pedro.
The fig likes dry sunny sites, the soil dry or drained. Excessive growth has to be limited to promote the fruiting. It thrives in both sandy and rocky soil. As the sun is really important it is better to avoid shades. Some varieties are more adapted to harsh and wet climates.

Propagation:
Figs plants are easy to propagate through several methods. Propagation using seeds is not the preferred method since vegetative methods exist that are quicker and more reliable, that is, they do not yield the inedible caprifigs. However, those desiring to can plant seeds of dried figs with moist sphagnum moss or other media in a zip lock bag and expect germination in a few weeks to several months. The tiny plants can be transplanted out little by little once the leaves open, and despite the tiny initial size can grow to 1 foot (30 cm) or more within one year from planting seeds.

Edible Uses:
Figs can be eaten fresh or dried, and used in jam-making. Most commercial production is in dried or otherwise processed forms, since the ripe fruit does not transport well, and once picked does not keep well. The widely produced fig newton or fig roll is a biscuit (cookie) with a filling made from figs.

Nutrition value and phytochemicals:
Dried figs are a rich source (> 20% of the Daily Value, DV) of dietary fiber and the essential mineral, manganese, while vitamin K and numerous other minerals are in moderate content (USDA, right table).

Figs contain diverse phytochemicals, including polyphenols such as gallic acid, chlorogenic acid, syringic acid, (+)-catechin, (?)-epicatechin and rutin

Medicinal Uses:
Ficus carica L. (Moraceae), its wide variety of chemical constituents, its use in traditional medicine as remedies for many health problems, and its biological activities. The plant has been used traditionally to treat various ailments such as gastric problems, inflammation, and cancer. Phytochemical studies on the leaves and fruits of the plant have shown that they are rich in phenolics, organic acids, and volatile compounds. However, there is little information on the phytochemicals present in the stem and root. Reports on the biological activities of the plant are mainly on its crude extracts which have been proven to possess many biological activities. Some of the most interesting therapeutic effects include anticancer, hepatoprotective, hypoglycemic, hypolipidemic, and antimicrobial activities. Thus, studies related to identification of the bioactive compounds and correlating them to their biological activities are very useful for further research to explore the potential of F. carica as a source of therapeutic agents.

Figs are used for their mild, laxative action, and are employed in the preparation of laxative confections and syrups, usually with senna and carminatives. It is considered that the laxative property resides in the saccharine juice of the fresh fruit and in the dried fruit is probably due to the indigestible seeds and skin. The three preparations of Fig of the British Pharmacopoeia are Syrup of Figs, a mild laxative, suitable for administration to children; Aromatie Syrup of Figs, Elixir of Figs, or Sweet Essence of Figs, an excellent laxative for children and delicate persons, is compounded of compound tincture of rhubarb, liquid extract of senna, compound spirit of orange, liquid extract of cascara and Syrup of Figs. The Compound Syrup of Figs is a stronger preparation, composed of liquid extract of senna, syrup of rhubarb and Syrup of Figs, and is more suitable for adults.

Figs are demulcent as well as nutritive. Demulcent decoctions are prepared from them and employed in the treatment of catarrhal affections of the nose and throat.

Roasted and split into two portions, the soft pulpy interior of Figs may be applied as emolient poultices to gumboils, dental abscesses and other circumscribed maturating tumours. They were used by Hezekiah as a remedy for boils 2,400 years ago (Isaiah xxxviii. 21).

The milky juice of the freshly-broken stalk of a Fig has been found to remove warts on the body. When applied, a slightly inflamed area appears round the wart, which then shrivels and falls off. The milky juice of the stems and leaves is very acrid and has been used in some countries for raising blisters.

Paw Paw

Botanical Name: Asimina triloba,
Family:
Annonaceae
Genus:
Asimina
Species:
A. triloba
Kingdom:
Plantae
Order:
Magnoliales
Names: The name, also spelled paw paw, paw-paw, and papaw, probably derives from the Spanish papaya, perhaps because of the superficial similarity of their fruit. Pawpaw has numerous other common names, often very local, such as prairie banana, Indiana (Hoosier) banana, West Virginia banana, Kansas banana, Kentucky banana, Michigan banana, Missouri Banana, the poor man’s banana, and Ozark banana.

Habitat: Native to North America.They are understory trees found in well drained deep fertile bottomland and hilly upland habitat.


Description:
It is a small, tropical~looking tree, seldom taller than 25 feet. Grown in full sun, the Pawpaw tree develops a narrowly pyramidal shape with dense, drooping foliage down to the ground level. In the shade it grows tall, with a more open branching habit, horizontally held leaves, and few lower limbs. Pawpaw (Asimina) is a genus of small clustered trees with large leaves and fruit. The genus includes the largest edible fruit indigenous to the continent.  Pawpaw is in the same family (Annonaceae) as the custard-apple, cherimoya, sweetsop, ylang-ylang and soursop, and it is the only member of that family not confined to the tropics.

Pawpaws are shrubs or small trees, reaching heights of 2 to 12 m tall. The northern, cold-tolerant common pawpaw (Asimina triloba) is deciduous, while the southern species are often evergreen.

The leaves are alternate, simple ovate, entire, 20 to 35 cm long and 10 to 15 cm broad.

The fetid flowers are produced singly or in clusters of up to eight together; they are large, 4 to 6 cm across, perfect, with six sepals and petals (three large outer petals, three smaller inner petals). The petal color varies from white to purple or red-brown.

The fruit is a large edible berry, 5 to 16 cm long and 3 to 7 cm broad, weighing from 20 to 500 g, with numerous seeds; it is green when unripe, maturing to yellow or brown. It has a flavor somewhat similar to both banana and mango, varying significantly by cultivar, and has more protein than most fruits.

The fruits are quite popular, but the shelf life of the ripe fruit is almost non-existent, for it soon ripens to the point of fermentation. Those who wish to preserve the fruit for the future do so by dehydration, making it into jams or jellies, or pressure canning by using the numerical values for bananas. In southern West Virginia pawpaws are made into a native version of banana nut cake or fruit cake, and baked inside canning jars, the lids heat-sealed to keep the food for at least a year.

* Bark: Dark brown, blotched with gray spots, sometimes covered with small excrescences, divided by shallow fissures. Inner bark tough, fibrous. Branchlets light brown, tinged with red, marked by shallow grooves.
* Wood: Pale, greenish yellow, sapwood lighter; light, soft, coarse-grained and spongy. Sp. gr., 0.3969; weight of cu. ft. 24.74 lbs.
* Winter buds: Small, brown, acuminate, hairy.
* Leaves: Alternate, simple, feather-veined, obovate-lanceolate, ten to twelve inches long, four to five broad, wedge-shaped at base, entire, acute at apex; midrib and primary veins prominent. They come out of the bud conduplicate, green, covered with rusty tomentum beneath, hairy above; when full grown are smooth, dark green above, paler beneath. When crushed they have a scent similar to a green bell pepper. In autumn they are a rusty yellow, which make spotting pawpaw groves possible from a long distance. Petioles short and stout with a prominent adaxial groove. Stipules wanting.
* Flowers: April, with the leaves. Perfect, solitary, axi
llary, rich red purple, two inches across, borne on stout, hairy peduncles. Ill smelling. The triloba refers to the shape of the flower, which is not unlike a tricorner hat.
* Calyx: Sepals three, valvate in bud, ovate, acuminate, pale green, downy.
* Corolla: Petals six, in two rows, imbricate in the bud. Inner row acute, erect, nectariferous. Outer row broadly ovate, reflexed at maturity. Petals at first are green, then brown, and finally become dull purple and conspicuously veiny.
* Stamens: Indefinite, densely packed on the globular receptacle. Filaments short; anthers extrorse, two-celled, opening longitudinally.
* Pistils: Several, on the summit of the receptacle, projecting from the mass of stamens. Ovary one-celled; stigma sessile; ovules many.
* Fruit: September, October

Cultivation: Pollinated by scavenging fruit flies, carrion flies and beetles, the flowers emit a weak to no scent which attracts few, if any, pollinators, thus limiting fruit production.

Larger growers sometimes locate rotting fruit or roadkill meat near the trees at bloom time to increase the number of pollinators. Asimina triloba is the only larval host of the Zebra Swallowtail Butterfly.

Asimina triloba is often called prairie banana because of its banana-like creamy texture and flavor.

The pawpaw is native to shady, rich bottom lands, where it often forms a dense undergrowth in the forest. Where it dominates a tract it appears as a thicket of small slender trees, whose great leaves are borne so close together at the ends of the branches, and which cover each other so symmetrically, that the effect is to give a peculiar imbricated appearance to the tree.

Although it is a delicious and nutritious fruit, it has never been cultivated on the scale of apples and peaches, primarily because only frozen fruit will store or ship well. It is also difficult to transplant because of fragile hairy root tentacles that tend to break off unless a cluster of moist soil is retained on the root mass. Cultivars are propagated by chip budding or whip grafting.
Uses:
In recent years the pawpaw has attracted renewed interest, particularly among organic growers, as a native fruit which has few to no pests, and which therefore requires no pesticide use for cultivation. The shipping and storage problem has largely been addressed by freezing. Among backyard gardeners it also is gaining in popularity because of the appeal of fresh fruit and because it is relatively low maintenance once planted. The pulp is used primarily in baked dessert recipes and for juicing fresh pawpaw drink or drink mixtures (pawpaw, pineapple, banana, lime, lemon and orange tea mix). In many recipes calling for bananas, pawpaw can be used with volumetric equivalency.

The commercial growing and harvesting of pawpaws is strong in southeast Ohio. The Ohio Pawpaw Growers’ Association annually sponsors the Ohio Pawpaw Festival at Lake Snowden near Albany, Ohio.

Because of difficult pollination, some may believe the flowers are self-incompatible. Cross pollination of at least two different varieties of the plant is recommended. The flowers produce an odor similar to that of rotting meat to attract blowflies or carrion beetles for cross pollination. Lack of pollination is the most common cause of poor fruiting, and growers resort to hand pollination, spraying fish emulsion, or to hanging chicken necks or other meat to attract pollinators.

This colonial tree has a strong tendency to form colonial thickets if left unchecked. It is ideal for creating a swift-growing habitat particularly in areas where frequent flooding can threaten erosion. The root systems are capable of holding streambanks steady, and grow well even in cold hollows with little exposure to winter sunlight.Click to learn more:...(1) ……(2).


Constituents & Uses:
The leaves, twigs, and bark of the tree also contain natural insecticides known as acetogenins, which can be used to make an organic pesticide[citation needed]. Pawpaw fruit may be eaten by foxes, possums, squirrels and raccoons. However, pawpaw leaves and twigs are seldom bothered by rabbits or deer. Bears particularly enjoy the fruit.

The delicious and nutritious fruit look like short, fat bananas. They have a fragrant aroma, a custardy texture, and a tropical taste. The best ones are rich, creamy and sweet, reminding some people of banana cream pie. Compared to apples, peaches and grapes, Pawpaw is higher in food energy, and has more than double the amount of vitamin C, and is much higher in minerals. It is higher in protein, fiber, and carbohydrate. It has a much higher content of amino acids in a good balance. It has mainly unsaturated fatty acids, and is a good source of linoleic and linolenic acids. They are high in antioxidants. Pawpaws are related to the tropical Annonacae, such as the Cherimoya .

History
The earliest documentation of pawpaws is in the 1541 report of the de Soto expedition, who found Native Americans cultivating it east of the Mississippi River. The Lewis and Clark Expedition depended and sometimes subsisted on pawpaws during their travels. Chilled pawpaw fruit was a favorite dessert of George Washington, and Thomas Jefferson was certainly familiar with it as he planted it at Monticello. The Ohio Pawpaw Growers’ Association lobbied for the pawpaw to be the Ohio state native fruit in 2006; this was made official in 2009.

Medicinal Properities:
Growers hope that potential medical use will eventually lead to increased market demand from the pharmaceutical industry.

The seeds also have insecticidal properties. Some Native American tribes dry and powder them and apply the powder to children’s heads to control lice; specialized shampoos now use compounds from pawpaw for the same purpose.

Currently, pawpaw extract is being reviewed as an alternative cancer treatment alongside conventional and approved treatments. This is not meant to replace conventional treatments, but is being examined for acetogenins and ATP production. Because acetogenin contents vary widely from tree to tree, only standardized extracts are acceptable.
