Scizocarp A schizocarp is a dry

fruit that develops from multiple carpels. When mature it splits up into mericarps. It have a stony pericarp, and usually only a single seed in each carpel matures, its often seeded.

Scizocarp Kinds:

1) Carcerulus

2) Regma

3) Cremocarp

4) Lomentum

1- Carcerulus Type of capsule (fruit) that grow from many

carpels and breaks up on maturity into one-seeded segments or nutlets, as in the Labiatae and Malvaceae.

2- Regma A kind of dry fruit, consisting of three or more

carpels, each which at length breaks open at the inner angle (as in Coca , develops of 3 corbels and geranium of 5)

3- Cremocarp Formed from two fused one-seeded carpels. The

carpels remain separate and form indehiscent mericarps that are attached to a central supporting strand (carpophore) for some time before dispersal. It is characteristic of the Umbelliferae (Apiaceae; carrot family).

4- Lomentum A dry dehiscent fruit, developed fron a single or

tow fused carples that contains one or more seeds. It resembles a legume but one ripening false spta divide the pod into one-seeded units or valves that fracture at maturity. The fruit has grooved rings from the outside splits when ripen but does not open and spread seeds.

If the fruit develop from a single carpel its called (lomentum pod as in Mimosa pudica). And if from two carpels with false barrier its called siliques as in radish.

Succulent “fleshy fruits” Is a soft fruits, where all or part ot the fruiting

cover is soft or succulent tissue such as oranges, tomatoes and grapes. The cover freshness help the distribution and dispersal of seeds and fruits

The Peri carp of this kind of fruit consists of three parts :

External (Epi carp), medial (Meso carp) and internal (Endo carp).

1. Epi carp:

Usually consists of one row of tissue cells, sometimes covered with a thick Kiotin layer.

2) Meso carp fleshy middle layer contains the vascular

Bundle

3) Endo carp The inside layer of fruit, which directly

surrounds the seed. It may be membranous as in citrus, or thick and hard as in the stone fruits as in peaches plumbs).

1- drupe. 2- Berry. 3- Ppme

1- Drupe These fruits develop from a single carpel, and

mostly from flowers with superior ovaries. The fruits cover consist of three layers:

1. Outer then layer

2. Med layer : grease, fleshy or fabric.

3. Inner layer: Typical drupes include peaches, plums, and

cherries The coconut is also a drupe Black butte blackberry, a bramble fruit of

aggregated drupelets

In coconut and walnut, the fruit grow from a fused carpel ovary. The fibrous mesocarp in coconut make it float on water. Inside the wooden part is the endosperm.

2- Berry a berry is a fleshy fruit produced from a single

ovary, superior as in grapes, orange and tomatoes. Or inferior ovary as in cucumber, bananas and pomegranate.

Its different that the inner layer is not hard it’s a soft tissue contains the seeds.

Its hare to recognize the med and inner cover as in grapes and tomatoes. But in date palms the tissue is soft and surrounds the seed. Bananas is a berry fruit with no seeds.

The lemon (Citrus lemon) is a hesperidium, a berry with a leathery rind. The exocarp (peel) contains volatile oil glands (essential oils) in pits. The fleshy interior (endocarp) is composed of separate sections (carpels) filled with fluid-filled sacs (vesicles) that are actually specialized hair cells.

The tomato (Lycopersicon esculentum) is technically a botanical fruit referred to as a berry. Most of the interior tissue of a true berry is soft and fleshy.

The calyx is cut away on right fruit to show the numerous stamens. The fruit is technically a leathery-skinned berry containing many seeds, each surrounded by a juicy, fleshy aril.

The watermelon is a good example of a pepo (gourd) , a berry with a hard, thick rind. The fruit out of a inferior ovary , fused carples and receptacle.

3- Pome

The seed-bearing ovary (core) is surrounded by a thick, fleshy hypanthium that is not part of the pericarp. It derived from the fusion of the bases of the perianth segments (petals and sepals). In the pome, the thickened, fleshy hypanthium is fused with the ovary wall .

It is not correct from the scientific point of view to call (outter, med and inner covers ) of this type of fruit, as the pome fruit is called also false fruit

Aggregate fruits

Aggregate fruit grow of multiple sepreated carples flower on a fleshy receptacle.

There are different types : 1- aggregate of achenes 2- Aggregate of follicles 3- Aggregate of drupelets 4- Aggregate of berries 5- Aggreagae of Samar

1- aggregate of achenes

As in rose, inside the receptacle cavity

2- Aggregate of follicles

As in sterculia and calotropis procers. The fruit consists of two or more pods

3- Aggregate of drupelets

As in rubus, where evey carple gives a drupelet, each aggregate cluster of fleshy drupelets developed from a single flower.

4- Aggregate of berries

As in Annonaceae

5- Aggregate of samar

As in Acer

Composite or multiple fruits

A composite fruit develops from a whole inflorescence. At ripening all the flowers in the inflorescence get fused to form multiple fruit. The peduncle and fused flowers also become fleshy. They have following types:

1) Sorosis

2) Syconium

1. SorosisIt develops from spike, catkin or a spadix. At

maturity the ovaries, perianth leaves and peduncle becomes fleshy and get fused to form a composite fruit e.g. mulberry, jack fruit, pineapple

As in Ananas compsus

2. SyconusIt develops from hypanthodium having a pear shaped receptacle which become fleshy and bears numerous achenes in inner surface e.g. fig, banyan etc.
