Abstract:

Abstract: Taking anti-waterlogging genotype Henan 1 and No waterlogging genotype Ji Zhi-1 as the experimental materials, the effects of varied waterlogging time during full flowering stage on the physiological indices and yield characters of different genotype sesame were studied. The results showed that: under the conditions of waterlogged in full flowering period, the specific leaf weight, the content of chlorophyll and the root activity of sesame declined gradually as the time waterlogged extended . When the waterlogged time lasted for 72h, the specific leaf weight, the content of chlorophyll and the root activity of sesame declined sharply and the differences reached the extremely significant level (P <0.01) compared with the control. The yield characters of all the waterlogging treatments dropped significantly compared with the control.
