摘要
对国产丽豆属间断分布的 2个种丽豆 Calophaca sinica 和新疆丽豆 C.soongorica 进行了形态、地理分布及其生态学特性的研究 ,其中包括叶表皮微观结构、花粉和果皮形态、种皮特征以及分布现状、生态学适应性等 ,结合古地理、气候、植被等的变迁 ,探讨了丽豆属的起源、形态分化及其环境解释以及现代分布式样的成因 。
The two disjuncted species of Calophaca Fish. ex DC. from China (C. sinica and C.soongorica)were studied, mainly on their morphology, geographical distribution and ecological characteristics, including their leaf epidermal features, pollen and carpodermis morphology and testa features, as well as their distribution pattern and ecological adaptation etc. By combining the changes of ancient geography, climate and vegetation, the origin, morphological differentiation as well as its environmental explanation, and the causes of formation of its modern distribution patterns of the genus Calophaca were discussed. Some measures and suggestions concerning the utilization and protection of resources of Calophaca were also provided.
