淹水对大豆生长和产量的影响
Effects of Flooding on Growth and Yield of Soybean
摘要
Abstract
Effects of flooding stress on growth and yield of soybean( Glycine max var. Nannong99-6) was studied by pot experiment. The results showed that flooding stress( water level up to cotyledon node of soybean) inhibited the growth of soybean. The main roots and lateral roots of soybean gradually decayed with prolonging of flooding time. Adventitious roots produced from the flooded part of stem, which helped soybean to adapt to flooding environmental conditions. Biomass, leaf area, photosynthetic rate (Pn) ,and other photosynthetic parameters increased within 10 days after treatment,but decreased with the lasting of flooding stress time. Chlorophyll content decreased to the end of the experiment. While malonyldialdehyde( MDA)and hydrogen peroxide ( H2O2 ) contents increased with prolonging of flooding time,and were significantly higher than those of control. As a result, pod number per plant and yield decreased. In sum,photosynthetic parameters,MDA and H2O2contents,etc. ,had no significant differences as compared with control within 10 days after treatment. It could be concluded that 10 d might be the critical time of flooding for this soybean cultivar.关键词
