摘要
采用盆栽试验的方法,研究了不同熟相冬小麦品种的根系生长特性。试验结果表明:熟相与小麦生长后期根系活力和根干重的乘积有密切关系,但后期根系活力是影响熟相的主要因素。熟相较好的小麦品种在开花后期根系活力和根干重乘积较大;而熟相差的品种,生长后期根系活力和根干重乘积小。旗叶叶绿素含量与品种熟相基本无关。
The characteristics of root system growth of winter wheat varieties with different maturing phases were studied by pot experiment.The results indicated that the maturing phase was closely related to the product of root vitality and root dry weight at the later growth stage of wheat,and the root vitality at the later growth stage was the main factor influential to the maturing phase.The product of root vitality and root dry weight at the later flowering stage of wheat variety with better maturing phase was s...
