| 摘 要： | 采用小区试验,在施磷和不施磷条件下,研究了不同磷效率玉米自交系干物质积累的动态变化.结果表明:在苗期干物质积累过程中呈现出物质由老叶转移至新叶的趋势.其中,磷的中效基因型表现为较强的递减趋势,而低效基因型表现为较弱的递减趋势.在不施磷处理条件下,中效基因型的干物质积累量大于低效基因型.

| Abstract: | The dynamic change of dry materil accumulation of different phosphorus efficiency maize self-bred line was analyzed under the conditions of whether applying phosphorus or not in district experiment.The experimental results demostrated that the old leaf may be transformed into new one in seedling stage.Among them,the middle efficiency genotype of phosphorus is shown as stronger decreasing trend of phosphorus.And the poor efficiency genotype is shown as weaker decreasing trend.The dry material accumulation of middle efficiency genotype of phosphorus is greater than that of poor efficiency genotype,if phosphorus is not applied. |
