【摘要】 本文报道了不同抗旱类型大豆品种游离脯氨酸在水分亏缺和无亏缺条件下的不同生育期累积动态变化。试验结果表明:在正常水分条件下,大豆品种的游离脯氨酸含量存在差异。游离脯氨酸的累积从结荚期至鼓粒后期随着生育的进展具有逐渐增加的趋势。水分亏缺条件下,所试大豆品种(黑农26、绥农4号、呼80—1001、安丰1号、庆选101)游离脯氨酸的累积能力均高于无水分亏缺条件下的累积能力,且均达到了显著水准。不同抗旱类型的大豆品种(黑农26,绥农4号,庆选101、呼80—1001)游离脯氨酸在不同生育时期累积能力不同。游离脯氨酸的累积能力在结荚期表现最高。更多还原

【Abstract】 This paper is the report of the behaviour of free-proline accumulation in various drought-resistance types of soybean cultivars under water-stress and non-stress condition in various growing periods. The results indicated that free-proline contents differed among soybean cultivars under non water stress condition and gradually increased along with growth and development from pod-setting to late pod-filling stage . The ability of free-proline accumulation in soybean cultivars was higher under water-stress than under non-water-stress and the difference was statistically significant . The ability of free-proline accumulation was different among various drought-resistante type of soybean cultivarsin different growing periods. The highest was in pod-setting stage.更多还原
