病原菌与自然植物种群Ⅱ病原菌与植物种群生物学

PATHOGENIC FUNGI AND NATURAL PLANT POPULATIONSⅡ.Pathogenic fungi and plant population biology

病原菌在自然植物种群中普遍存在，其对寄主植物的生长发育，对寄主植物种群的大小、结构、动态、遗传和进化等都有重要影响。本文着重论述：１）病原菌对寄主植物个体的影响；２）病原菌对寄主植物种群生物学的影响；３）菌病发生的空间格局；４）病原菌感染的种群模型。

Pathogenic fungi are common in natural plant populations,which exert impacts of the size,structure,dynamics,genetics and evolution of host plant populations.This paper is to review:1)the effects of pathogenic fungi on individual host plants;2)the effects of pathogenic fungi on the population biology of host plant;3)the spatial patterns of disease incidence;4)the population models of fungal infections.
