Floral organogenesis and development of Litchi chinensis Sonn.cv.Guiwei
摘要
Abstract
Floral organogenesis and development of Litchi chinensis Sonn. Cv. Guiwei were studied under an SV11 stereomicroscope and JSM-6360LV scanning electron microscope. The results showed that the inflorescence primor dium was initiated firstly,followed by the formation of several unequal flower primordia. Later,the four sepal primor dia were formed asynchronously with the initiation of one of the para-positions preceding the other one. Then,six to ten stamen primordia were initiated in whorls simultaneously. Finally,carpel primordia initiated:two or three(rarely four)carpel primordia appeared simultaneously and closed up gradually to form the ovary. In the female flowers,stig ma and style were obviously differentiated and the stamens were degenerative. In the male flowers,the stamens grew normally but the ovary was degenerative. In hermaphrodite flowers, stamens and pistil fully developed. The pollen grains were spherical with three germinal furrows and sculptures are striate.关键词
