不同花生品种高产生理参数研究

以远杂9102和国内生产上种植面积较大的两个小果型品种白沙1016、鲁花12号及两个大果型品种海花1号、豫花15号为材料,考查叶绿素含量、叶面积指数、叶片可溶性糖含量、经济系数等重要生理参数。结果表明,远杂9102功能叶叶绿素含量在小果品种中最高,叶片叶绿素含量在生长后期减少的速度慢于同类型其它品种;叶面积指数位于最适叶面积范围之内;叶片可溶性糖含量在成熟期还保持增长趋势;是参试品种中经济系数最高的品种。由此说明,远杂9102具有高产的生理基础。

Physiological parameters of high yielding peanut cultivars

One of the important purposes of peanut breeding is to increase the yield.Understanding of physiological parameters of high yielding peanut cultivar had been great focus of all researchers.This experiment selected Yuanza 9102 and small fruit varieties,such as,Baisha 1016,Luhua 12 and large fruit varieties,such as Haihua 1,Yuhua 15 as the materials.The research used the chlorophyll content,leaf area index,content of leaf soluble sugar and economic coefficient as the parameters.The result showed that the chlorophyll content of functional leaves was the highest in the small fruit varieties.The decrease of chlorophyll content was slower than that of other varieties.Leaf area index was in the optimum range.Content of leaf soluble sugar of Yuanza 9102 still increased on maturity stage and the economic coefficient was the highest among all varieties.Yuanza 9102 had physiological characteristics of high yield.
