在不同温度条件下不同耐热性水稻品种的功能叶和籽粒特性的差异分析

Differences Analysis on Functional Leaves and Grain Characteristics of 6 Rice Varieties with Different Heat Resistance under Different Temperature Conditions

以6个不同耐热性水稻品种为材料,比较了不同温度条件下各品种生物学特性差异。结果表明,高温胁迫后,所有品种功能叶退绿长度及籽粒转黄进程均加快,功能叶面积降低;耐热性强的水稻品种其功能叶退绿长度、籽粒转黄进程慢于耐热性较差的水稻品种,功能叶面积则大于耐热性差的品种。

The biological characteristics of 6 rice varieties were compared under different temperature conditions . The results showed that six varieties’ fading rate of functional leaves and grain yellowing rate became fast, functional leaves became decreased after high temperature stress. Compared to heat-sensitive varieties, heat-tolerant varieties have slower fading rate of functional leaves and grain yellowing rate, but higher functional leaves area.
