摘要
通过对白皮、彩色、黑皮、红皮花生及白沙1016、花育16、花育19、花育20、花育22共9个不同类型品种(系)干物质积累动态规律研究表明,各品种(系)干物质积累过程均呈"S"型曲线特征,可以用Logistic方程进行很好的拟合。开花期至结荚初期是花生地上部干物质积累的关键时期,开花期各品种(系)花生干物质积累量平均占总积累量的45.2%,荚果期占近30%。高产花生品种有较高的生物学产量和根/冠比值,供试品种(系)成熟期根/冠比值平均达0.618。
The dynamic regularity of dry matter accumulation in nine different varieties of peanut, white -coat, colored- coat, red- coat and black -coat peanut, Baisha 1016, Huayu 16, Huayu 19, Huayu 20 and Huayu 22, were studied. The results indicated that the dry matter accumulation of all varieties showed as an ＂S＂ curve, which could be explained by the Logistic equation. The key period of aboveground dry matter accumulation was from flowering stage to early pod setting stage, in which, the average dry matter of all varieties at flowering stage was 45.2% of total accumulation while that at pod setting stage was 30%. High - yielding peanut varieties have higher biomass and root/shoot ratio. The average root/shoot ratio of the tested varieties reached 0. 618.
