Microsporogenesis and Male Gametophyte Development of Artemisia annua L.
摘要
Abstract
Artemisia annua L. is only medicine source plant of artemisinin,a very effective antimalarial medicine. In this paper the conventional paraffin section was adopted to observation of the microsporogensis and the male gametophyte devel-opment of A. annua.The results are as follow:The anther has 4 chambers and organizes in a butterfly shape in its transec-tion. The development of anther wall belongs to the monocotyledonous type. The two middle layers of anther wall change from thickness into thinness in the earlier stage of the anther development and disintegrate in the dyads stage of the pollen mother cell (PMC). The tapetum,of which each cell always disintegrates in the original position,is the secretory type.The cytokinesis after meiotic division of PMC is simultaneous type,and the microspore arrangement in the tetrad is tetrahe-dra1.The mature pollen grains,which contain 1 vegetative cell and 1 reproductive cell,belong to a 2-cell type.关键词
