The Anther Structure and Pollen Ontogeny in Hosta Tratt.

Abstract

Abstract: The anther’s structure and pollen ontogeny in Hosta Tratt.containning 6 species and 4 related taxas were studied by light microscopy.The results are as follows:(1) The mature anther wall consists of 1 epiderm,1 endothecium,1 middle cell,and 1 tapetum.(2) The four microsporangia arranges in linear mode and occur on the introrse side.(3) The male-gametogenesis is non-homogeneous.(4) The mature pollen is 3-cellular and the vegetative cell is filled with a large number of starch grains.(5) 2n=2x=60.(6) About 9～13 traces were often seen in the tepals in transection.Consequently,the authors agree with the view of Takhtajan (1997) and Wu et al.(2003) and elevate the Genus Hosta Tratt.to level of the Family Hostaceae.

Key words: Hosta Tratt., anther, pollen ontogeny
