(biology) release of material by splitting open of an organ or tissue; the natural bursting open at maturity of a fruit or other reproductive body to release seeds or spores or the bursting open of a surgically closed wound
Opening of an organ by its own means (such as an anther or a seed pod) to release its contents.
A rupture, as with a surgical wound opening up, often with a flow of serous fluid.

Origin: From Modern Latin dehiscentia (in Linnaeus), from dehiscentem, present participle of dehiscere.
the act of gaping
a gaping or bursting open along a definite line of attachment or suture, without tearing, as in the opening of pods, or the bursting of capsules at maturity so as to emit seeds, etc.; also, the bursting open of follicles, as in the ovaries of animals, for the expulsion of their contents
Origin: [Cf. F. dhiscence.]
Dehiscence is the splitting at maturity along a built-in line of weakness in a plant structure in order to release its contents, and is common among fruits, anthers and sporangia. Sometimes this involves the complete detachment of a part. Structures that open in this way are said to be dehiscent. Structures that do not open in this way are called indehiscent, and rely on other mechanisms such as decay or predation to release the contents. A similar process to dehiscence occurs in some flower buds, but this is rarely referred to as dehiscence unless circumscissile dehiscence is involved; anthesis is the usual term for the opening of flowers. Dehiscence may or may not involve the loss of a structure through the process of abscission. The lost structures are said to be caducous.
