以平均萎蔫株率、平均死亡株率为鉴定指标对15个国内近几年选育的白芝麻品种进行了淹水鉴定,结果表明:在同一小区同一天内,下午萎蔫株数高于上午萎蔫株数,萎蔫植株应以下午调查为好;撤水后3d内萎蔫株率有不同程度的波动,但总体水平相差不大,撤水后第1天的萎蔫株率可以作为调查的指标;光照和温度是影响植株萎蔫发生的主要天气因素;冀芝1号在整个鉴定过程中没有出现萎蔫死亡现象,为抗性优良品种,并且其早期耐淹的能力能遗传给后代。豫芝4号(新)、陕芝3号在整个鉴定中出现萎蔫或死亡植株较少,为耐渍品种,其余品种抗性一般或差。
The results showed that the number of wilt plants in the same plot was higher than the number of wilt plants in the morning on the same plot in the same plot in the same plot, The wilting plants should be investigated in the afternoon as well; within 3 days after water withdrawal, the rate of wilting plants fluctuated in varying degrees, but the overall level did not differ much. The rate of wilting plants on the first day after water withdrawal could be taken as the index for investigation. Which affected the main weather factors of plant wilting; Ji Zhi 1 did not appear wilting death phenomenon throughout the appraisal, which was an excellent resistant variety, and its early resistance to flooding could be passed on to future generations. Yuzhi No. 4 (new), Shaanxi No. 3 in the identification of wilted or dead plants appear less resistance varieties, the other varieties of general or poor resistance.
