摘要
选用 3个不同熟期组大豆品种在花期以 1 5℃、1 5/ 1 0℃和 1 7/ 1 2℃低温处理 ,结果表明 ,超早熟品种Aldana花期对 1 7/ 1 2℃低温有较好的耐性 ;中晚熟品种吉林 2 9号花期对低温耐性最差。大豆在花期遇低温时一粒荚数增多 ,三粒荚数和单株荚数减少 ,导致单株粒数下降 ;
Three soybean varieties belonged to different maturity group were treated with low temperature (15℃, 15/10℃ and 17/12℃) at blooming stage. The results showed that early maturity variety Aldana could stand at the low temperature (17/12℃), while later maturity variety Jinlin 29 endurance to low temperature was worse at blooming stage. The increase of one seed pod and decrease of three seed pod and the numbers of pod per plant led to reduction of the numbers of grain per plant. The constant low temperature at blooming hinded podding and seedfilling of soybean seriously.
