In order to indicate the selenium absorption,accumulation and distribution of different Brassica napus cultivars in Qinghai province,this paper used a split-plot experiment and tested the content of selenium and the dry matter accumulation of different organs at harvest period in Brassica napus.The results showed that different Brassica napus cultivars had different abilities of selenium accumulation,the order was Qingza 2＞ Qingza 5＞ Qingyou 14.The selenium content in roots,stems,leaves,seeds,pods reached the highest at pod development-maturity stage (the 120th day).The selenium accumulation in roots,stems,pods,per plant was the highest at pod development-maturity stage (the 120th day).The selenium absorbed by Brassica napus were mainly distributed to reproductive organs (including seeds and pods),and selenium contributed in pods was higher than other organs.Then,Qingza 2 had the strangest ability of absorbing selenium,the pod development stagematurity stage (the 120th day) was the crucial period of absorbing selenium in Brassica napus,the selenium absorpted were mainly assigned in the reproductive organs.
