摘要
Abstract
In order to screen out rice varieties with alkali resistant,which are adapted for cultivation in Heilongjiang province.Taking 46 japonica rice varieties as test marterials,the screening test was carried out with mixed liquid of Na2CO3+NaHCO3 of 1∶3 mass ratio during budding stage.The relative alkali damage rate was calculated by bud length,root length,budding ratio,root weight and bud weight,the cluster analysis was carried.The results showed that Longdao17 and Longdao22 were more resistant to alkali stress during budding stage and Wuyoudao1 with the worst resistance among 11 rice varieties with better alkali resistant.关键词
