THE MICROSPOROGENESIS AND THE F0RMATION OF MALE GAMET0PHYTE OF TWO SPECIES IN PARIS L.

Abstract

Abstract: The process of the microsporogenesis and the formation of male gametophyte of two species in Paris L. (P.axialis, P. polyphylla var. yun- nanesis) is similar. The cytokinesis is succssive type. The pollen are shed at 2 --celled stage . The anther wall comprises 5 laryers. Tapetum belong the secretory type. The frequency of anormolous pollen grains in P. axialis is higher than in P. polyphylla var. yunnanensis, it probably related with the number of B- chromosomes and abnormal division of meiosis in meiocytes.

Key words: microsporogenesis, formation, gametophyte
