摘要
马占相思 (Acaciamangium)QLD19835家系树苗在人工气候室经低温处理后 ,未发生死亡 ,体内相关的生理指标产生明显变化 .随着温度不断下降至 - 6℃产生冻害导致植株的电导率大幅度升高 ,脯氨酸、可溶性糖和蛋白质的含量也显著升高 .表明马占相思QLD19835树苗对低温胁迫有一定适应能力 .脯氨酸、可溶性糖。
After the plants of Acacia mangium QLD19835 clone were treated with low temperature in phytotron, the relative physiological indication changed obviously. When the temperature was gradually reduced to -6℃, the electrical conductivity of the leaf blades raised by several folds. The contents of proline, soluble sugars, and soluble proteins increased greatly. The experimental results indicated that the plants of Acacia mangium QLD19835 clone could produced a preventing reaction to low temperature stress. The increase of the contents of proline, soluble sugars, soluble proteins might have an important role in cold tolerance property of the plants.
