First , the morphology , physiology of seed , biological traits , geographic distribution , ecological and community characteristics , karyotypes , nitrogenase activity of root nodules and chemical constituents of e . mollis were reviewed , respectively 本文对翅果油树的形态特征、种子生理生化、生态学特征、染色体数目、群落生态、生物学特性、固氮生物学以及矿物质和化学成分等方面研究进行了综述。
The nearest neighbors of each individual and the distances between each individual - neighbor pair in elaeagnus mollis communities were obtained by using the nearest neighbor ' s analysis . based on the primary results above , the spatial pattern and interspecific segregation in the communities were studied by x2 test with a subtable method of a n n nearest - neighbor contingency table 应用最近邻体法判定每个个体的最近邻体植株,得到每个基株-最近邻体种对的距离,进而采用n n最近邻体列联表的截表法,研究了翅果油数群落的种间分离。
The average number of alleles per locus ( a ) , percentage polymorphic loci ( p ) , observed heterozygosity ( ho ) and wright ' s fixation index ( f ) is 2 . 2 , 77 . 9 , 0 . 433 , - 0 . 138 , respectively . the species also had higher variation than that of the other woody angiosperms widespread . moreover , e . mollis has higher population genetic variation than that of 26 long - lived woody endemics with narrow geographic distributions Biosys - 2软件计算得知,在翅果油树种群中,每个位点等位基因的平均数a = 2 . 2 ,多态位点百分率p = 77 . 9 ,遗传多样性he = 0 . 375 ,遗传多样性水平明显高于蜂媒植物,而且也比其它的广布木本被子植物的遗传多样性水平为高。
