Types of dry fruits include achenes, capsules, follicles or nuts. Dry fruits can also be separated into dehiscent and indehiscent fruits. Dry dehiscent fruits are described as a fruit where the pod has an increase in internal tension to allow seeds to be released. These include the sweet pea, soybean, alfalfa, milkweed, mustard, cabbage and ...
Insertion point: There are three positions of insertion of the ovary at the base of a flower: I superior; II half-inferior; III inferior. The 'insertion point' is where the androecium parts (a), the petals (p), and the sepals (s) all converge and attach to the receptacle (r). (Ovary=gynoecium (g).)
The point of insertion, on the stem, of leaves or buds is a node, and the space between two successive nodes, an internode. The leaves, which emerge from the shoot, are specialised structures that carry out photosynthesis, and gas (oxygen and carbon dioxide) and water exchange.
One of the terminologies for describing the ovary refers to the point of insertion above the receptacle (where the other floral parts (perianth and androcecium) join and attach to the surface of the ovary. If the ovary is located above the point of insertion, it will be subterranean; if it is below, it will be infertile.

In botany, infructescence (fruiting head) is defined as the ensemble of fruits derived from the ovaries of an inflorescence. It usually retains the size and structure of the inflorescence. [1] In some cases, infructescences are similar in appearance to simple fruits. These are called multiple fruits.
Fruit trees are grown in a variety of shapes, sometimes for aesthetic appeal but mainly to encourage fruit production. The form or shape of fruit trees can be manipulated by pruning and training. Shaping and promoting a particular tree form is undertaken to establish the plant in a particular situation under certain environmental conditions, to ...
