陇东旱塬区小麦茎秆含水量与产量和水分利用效率的关系
Relationship Between Yield and Water Content of Wheat Stem and Water Use Efficiency in Loess Plateau of East Gansu
摘要
Abstract
The differences of grain yield,water use efficiency(WUE)and water content of stem in various genotypes of dryland winter wheat were studied with twelve winter wheat genotypes in Loess Plateau of East Gansu under dryland at heading stage and mid-filling stage . The results showed that significant difference among genotypes were found in grain yield,WUE and water content of stem . The water content in stem decreased with grain filling proceeding . The correlation between water content of stem with grain yield and WUE was significant at heading stage but was not significant at mid-filling stage . Therefore,the water content of stem can be used by breeding programs as a potential selection criterion for grain yield and WUE in wheat.关键词
