Topic: Dehiscent


  
  Fruit - Wikipedia, the free encyclopedia
Dry fruits may be either dehiscent (opening to discharge seeds), or indehiscent (not opening to discharge seeds).
Seedlessness in table grapes results from the abortion of the embryonic plant that is produced by fertilization, a phenomenon known as stenospermocarpy which requires normal pollination and fertilization.
Some fruits have coats covered with spikes or hooked burrs, either to prevent themselves from being eaten by animals or to stick to the hairs, feathers or legs of animals, using them as dispersal agents.

 Classification of fruit types
Dehiscent Fruits - Dry fruits which at maturity open by definite natural means to shed the contained seeds.
Legume- A dry dehiscent fruit developed from 1 carpel and at maturity splitting along both the dorsal and ventral sutures.
Follicle- A dry dehiscent fruit developed from 1 carpel and at maturity splitting along only one suture.

Fruits may be dehiscent, which open to shed their seeds, or indehiscent, which remain unopened and are dispersed as a single unit.
Simple fruits (for example, peaches) are derived from a single ovary, whereas compositae or multiple fruits (for example, flberries) are formed from the ovaries of a number of flowers.
Animals often act as dispersal agents either by carrying hooked or sticky fruits (burs) attached to their bodies, or by eating succulent fruits, the seeds passing through the alimentary canal unharmed.

 Botany online: Features of Flowering Plants - Fruits and Seeds
Two types of fruits with a generally different mechanism of seed distribution exist: dehiscent and nondehiscent fruits.
Dehiscent fruits set the seeds free by opening of the fruit that remains itself with the mother plant.
Dehiscent fruit types are follicles, pulses, pods and capsules.

 A Systematic Treatment of Fruit Types
He also defined dehiscence types for capsular fruits such as loculicidal, septicidal, septifragal, and circumscissile, and provided illustrations for 15 fruit types, most of which were not described or defined; represented were caryopsis, achene, polachenium, glans, elaterium, follicula, silique (including silicule), gousse (= legume), capsule, drupe, nuculanium, melonidium, peponidium, berry and syncarpium (L-C Richard 1798).
The fleshy fruited ephedras have additional lower sterile scales, which are connate at base, and which loosely envelope the seed(s), described as a fleshy false berry in the Flora of USSR, which corresponds to arcesthida; however, in the dry ephedra cones, the seed disperal unit may be referred to as a galbulus.
Another was capsula tubulosa for those that dehisce incompletely, irregularly or are surrounded by perianth, and this included their capsula rompente, velatidium, capsula lobata, capsula dentada, capsula septifraga, siliqua (including silicula), poricidal capsule, circumscissile capsule, and ceratium.

Dry fruits - generally grey, brown, or another dull color, with a very thin and dry ovary wall, so that the food is largely confined to the seeds.

Capsule - dehiscent fruit composed of two or more carpels, generally with several or many seeds in each carpel, as in Gossypium spp.

 Olympus MIC-D: Reflected Light Gallery - Common Garden Geranium (Pelargonium x hortorum)
Wild geranium flowers are used by plant taxonomists and botany classes to illustrate flower structure including the petals, sepals, and carpals.
The simple, dry dehiscent fruit of the geranium is a prime example of a schizocarp and when ripe, breaks into single-seeded sections.
Derived from the ancient Greek word for crane, geraniums were so named because the long beak of the fruit was thought to resemble the bird's distinctive beak.
