- 摘要:
- 由于地理、进化和人工选择的原因，水稻中的硒素含量因品种类型而异，且差异很大。为更好地开发黑龙江省富硒水稻资源，通过田间试验对黑龙江水稻品种进行富硒品种筛选。结果表明：同一积温带不同品种间水稻硒含量差异较大，其中第二积温带品种间差异最大，含量最高的水稻品种含硒量为83.73 mg?kg-1，是含硒量最低品种11.78 mg?kg-1的7倍。相同条件下，不同水稻品种平均硒含量差异都极显著，表明进行富硒品种筛选的必要性。
- Abstract:
- Because of geographical reasons,evolution and artificial selection,the selenium content in rice varied with genotypes,great difference.In order to develop the rice resources with selenium,taking rice varieties of Se enriched in Heilongjiang province,field experiment was conducted.The results showed that with the same accumulated temperature among different varieties of rice selenium content difference was greatly,varietal difference was maximum in second accumulated temperature ,of which the highest selenium content for 83.73 mg?kg-1 of rice variety was 7 times of the lowest selenium content variety(11.78 mg?kg-1).Under the same conditions,the difference of selenium content among different rice varieties were extremely significant,that was necessary to select varieties of selenium.
