无性孢子

产生单一种类无性孢子的过程或现象。

The development of a single kind of asexual spores .

内生孢子一种小的无性孢子，如那些由某些细菌所形成的孢子

A small asexual spore , as that formed by some bacteria . Clostridium sporogenes

根据菌落形态和菌丝体细胞结构的变化，色素分泌及无性孢子产生，结合EST、POD同工酶谱带变化，可初步进行种性变异的检测。

And the species variance could primarily be investigated according to the change of colony morphology and mycelium cell structure , the pigment secretion and the conidium formation accompanied with the zymogram band change of EST and POD isozyme .

芽生孢子是许多真菌通过出芽方式产生的无性孢子，在液体发酵中主要以这种形式大量繁殖。

Blastospores are asexual reproductive spores that originate by budding , as in yeasts and many filamentous fungi . In liquid culture , many fungi reproduce in this form .

该菌分布广、寄主范围大，不产生无性孢子，常以菌核形态习居土壤，是玉米、水稻、大豆、马铃薯、黄瓜等植物纹枯病的致病菌。

Rhizoctonia solani is characterized by extensive distribution , wide host range and no asexual spore . It normally resided in soils by form of sclerotia and was pathogenic fungi for many plants , such as rice , corn , soybeans , potatoes and cucumbers .
