spore germination
2.According to the characteristics of spore germination and protonemal development P.sinense is confirmed in P.sinense and in accordance with Nishida classification of spore germination types of moss plants to belong to Ptychomitrium-type.
3.The suitable temperature for spore germination was 15 - 28℃ , the optimum temperature was 25-28℃ . Temperature over 30℃ inhibited spore germination. The suitable temperature of feritilization and growth of young sporophyte was 25-28℃, the optimum temperature being 28℃ .
4.The extract of Acacia catechu did not inhibit the growth of mycelium, but restrained the spore germination by 100%.
5.The results show that 20% of tricyclazole and IBP and 30% of isoprothiolane have better effects for controlling Magnapothe grise in rice field. Three pesticides strongly control spore germination (only 0. 33%~1. 0% of spore germination rate).
6.The green, filamentous growth that arises from spore germination in liverworts and mosses and eventually gives rise to a mature gametophyte.
7.The effects of 70% Mancoze b, Thtophanate-methyl. thiram,70% Throphanate-Methyl,45% Lime sufur,55% Yi shuangmengxing WP and 50% Tuzet WP on spore germination were the highest,and th e spore germinating rates were zero at four concentrations. 1∶1∶100 Bordeaux mi xture was both effective on mycelial growth and spore germination.
8.1. Describing the characters and developmental features of spore germination and protonema development of moss applied in this research by microscopy.
9.In plant kingdom, having a protonema stage after spore germination is a specific character of moss and a marked difference compared with other plant group.
10.BTW 4 1 was difficult to use inorganic nitrogen for growth, however its spore germination rate was high in solution containing peptone and yeast juice.
