生育后期湿涝胁迫对不同花生品种干物质积累及产量性状的影响
Effects of Waterlogging Stress on Dry Matter Accumulation and Yield Traits of Different Varieties of Peanut at Late Growth Stages
摘要
Abstract
In order to solve the problem of waterlogging of peanut and accelerate the promotion pace of new varieties with high quality,high yield and high resistance in the south of Henan,simulated artificial flooding was used to screen the suitable varieties with waterlogging tolerance.The results showed that waterlogging stress could reduce 35%-63% of the yield,and affect all aspects of the growth and development,such as the leaf SPAD values,dry matter accumulation,root activity,the pod number and effective pod number per plant decreased,and the root morphology was damaged.Different varieties had different waterlogging resistance.Yuanza 9307 and Yuanza 9102 had strong resistance to waterlogging stress.The relative value of yield,leaf SPAD value,effective number of pod,total root length,root activity under stress and normal conditions were 0.65,0.89,0.69,0.62,0.86 and 0.60,0.80,0.53,0.86,0.64 for Yuanza 9307 and Yuanza 9102 respectively.The waterlogging resistance of Baisha 1016 was poor,the relative value of yield,leaf SPAD value,effective number of pod,total root length,root activity under stress and normal conditions were 0.37,0.65,0.28,0.33,0.73 respectively.The result of comprehensive evaluation by membership function method showed that Yuanza 9307 and Yuanza 9102 had the good resistance to waterlogging stress,which were suitable for planting in the south of Henan province.关键词
