parthenocarpy



parthenocarpy defined in 1951 year

parthenocarpy - parthenocarpy;
parthenocarpy - Formation of fruit without fertilization. In most plants development of a fruit from the ovary can proceed only after fertilization has occurred, but in a number of plants fruit development regularly takes place from unfertilized flowers. Such fruits, e.g. banana, pineapple, are seedless but otherwise normal in appearance. Parthenocarpy can also be induced in unfertilized flowers, e.g. in tomato, by application of certain auxins. It has been suggested that fertilization provides a stimulus for production of hormone which, in turn, induces development of fruit tissue, and that where natural parthenocarpy occurs, sufficient hormone to enable fruit development to proceed is produced by the plant independently of stimulus of fertilization.
