Abstract
This research dealed with the seed traits and its reproductive capacity of Haloxylon ammodendron acquired from 6 sources.The results showed that(1) There are significant differences of seed traits and its reproductive capacity among 6 sources.The differences among the seed quality indexes are greater than that among morphological indexes.The difference among seed weights of individual tree is the greatest,that among kernel weights is the following,and that among fruit wing legths is the smallest,for the reproductive traits,the difference of survival rate is significant greater than that of germination rate.(2) There are very significant difference(0.01 level) of genetic variations of seed traits and reproductive capacity among 6 sources,and significant difference(0.05 level) of environmental factors,seed quality is determined mainly by genes,and seed reproductive capacity is determined by genes,soil properties and environmental factors.(3) Seed traits have positive correlation to germinate rate and survival rate.All the seed traits and reproductive capacity indexes have significant paired coorelation except fruit wing length with survival rate.The genetic capacities of all the indexes have positive paired correlation except that those of wing length have negative correlation to the other indexes.(4) Among the fruit wing length,kernel weight,individual seed weight,germination rate and survival rate,individual seed weight has the highest variation and survival rate has the lowest variation,seed traits of 6 sources have higher repetition(0.8580～0.9737).Controlled by genes,the good result can be gotten through source selection.Provenance selection with germination rate index can increase genetic process by 2.40～24.86%(10 % of selection rate) compared to the provenance selection with survival rate.Through comprehensive assessment,seed traits and its reproductive capacity can be sorted as Dengkou,Inner Mongolia Qinghai Gansu Wuhou Banner,Inner Mongolia Ekina Banner,Inner Mongolia Xinjiang.
