| 摘 要： | 2008年6～10月,对试验区种植的18个1 a生厚朴(Mqgnolia officinalis)种源的苗高、地径等形态性状进行测量及分析,研究了厚朴不同种源苗高、地径的遗传变异、生长节律及与地理、环境因子的关系.结果表明:各种源的苗高、地径差异极显著,且有显著相关性;不同种源厚朴在6～7月生长缓慢,7月后加快,9月后生长缓慢;环境因子及地理因素对厚朴种源的遗传变异有显著影响,且以地理因素为主;依据种源间苗高、地径生长性状的二维非度量多维标度排序结果,18个种源被划分为5个种源区,根据种源苗期生长优劣,初步筛选出道县、桑植、安化3个优良种源.

| Abstract: | The morphological traits,such as seedling height and basal diameter of 1-year-old seedlings of 18 provenances of Magnolia officinalis,were measured from June to October,2008,and the genetic variation,growth rhythm and their relationships with environmental factors were studied.The results showed the extremely significant differences in seedling height and basal diameter among the 18 provenances,and also a significant correlation each other.For all of the provenances,the growth of seedlings was slower from J... |
