我国芝麻主栽品种耐湿性鉴定分析
Evaluation of the Waterlogging Tolerance of the Main Sesame Cultivars in China
摘要
Abstract
In present study,43 main sesame cultivars from China were treated for their waterlogging tolerance. After 36 h waterlogging stress at full flowering stage,the percentage of normal plant of the cultivars ranged from zero to 42. 4% with average 17.7% ,and the average harvest yield decreased into 0 -95. 4 g with average 28. 5 g,about 0 -55.2% of the yield of CK. The correlation coefficient between the harvest yield and the percentage of normal plant or the yield reduction percentage after treatment was 0.77 and -0. 64,respectively. The study also found the waterlogging tolerance of the southern cultivars was higher than those from northern regions, and the recent released cultivars had higher percentage of normal plant than the old cultivars after treatment. In addition, the cultivars authorized by nation were better than those authorized by locations in yield after waterlogging stress. The study also indicated most of the present sesame cultivars were sensitive to waterlogging stress. Relatively, Xiongzhi No. 1 with higher percentage of normal plant,and Zhongzhi No. 13 with higher harvest yield after treatment may be useful in studying waterlogging tolerance.关键词
