摘要: 白车轴草(Trifolium repens)在与其病原菌白车轴草单孢锈菌(Uromyces trifolii-repentis)的长期相互作用中分化形成了抗病型(Resistance)无性系和易感型(Susceptibility)无性系。该研究工作旨在了解:1)在种间竞争不断增强的环境梯度中,抗病型无性系和易感型无性系的生长表现有何区别?2)在同样的实验条件下,分别对抗病型无性系和易感型无性系进行接种感染后,两者的生长表现又有何区别?在一严重感病的白车轴草自然种群中,分别标定17个抗病型无性系和14个易感

Abstract: In the long-term interactions with its pathogenic rust fungus Uromyces trifolii-repentis, Trifolium repens has evolved two genotypes of clones: resistant and susceptible clones. Two questions were addressed in this study. Firstly, whether the susceptible
