摘要
通过测定37℃热驯和44℃高温胁迫下绿豆(Phaseolus radiatus L.)下胚轴生长量及脯氨酸、可溶性糖和抗坏血酸含量的变化,探讨高温胁迫对绿豆生理的影响。结果表明,高温胁迫使绿豆下胚轴生长量和抗坏血酸含量下降,并导致脯氨酸和可溶性糖含量上升。37℃热驯则能适当提高绿豆耐热性。本文还讨论了上述生理指标变化对绿豆生长发育的影响。
To explore the physiological effect of high temperature stress on green gram（Phaseolus radiatus L.）,the growth and content of proline,soluble sugar and ascorbic acid of green gram hypocotyls was examined under heat acclimation at 37 ℃and stress at 44 ℃.The results showed high temperature stress resulted in decrease in hypocotyl growth and ascorbic acid content while increasing in content of proline and soluble sugar content.Heat acclimation at 37 ℃ enhanced the thermostability of green gram.The effect of the changes of these physiological indices on green gram growth was also discussed.
