| Abstract: | Various shapes of cones and seeds of Pinus banksiana were investigated.Result shows that: the differences among the length,width,number of seeds in cones,seed weight are not significant;the differences among dry and fresh weight of cones are significant.1 000-grain weight for seeds of Pinus banksiana is 3.506 g.The germination tests of seeds which are collected in different years were conducted.Result shows that there is no significant difference in germination rate,and there are 20 plump seeds in average c... |
