摘  要：
研究了水涝胁迫对银杏叶片中内源激素和细胞溶质含量的影响。研究结果表明,水涝胁迫使银杏叶片中GA1+3I、AA和ZRs含量明显降低,在受涝后的第35天时,银杏叶片中的GA1+3I、AA和ZRs含量分别降为7.13、3.27、9.67 nmol/g。正常情况下,银杏叶片中ABA含量在4.74~8.57 nmol/g,始终保持在较低水平,受涝后的第51、01、5、20、25天,银杏叶片中ABA含量分别为15.35、18.41、20.56、22.632、4.91 nmol/g,明显比对照高,且随胁迫时间的延长,增加的幅度呈上升趋势。水涝胁迫使银杏叶片中可溶性总糖、还原糖、蔗糖和脯氨酸含量增加,而使银杏叶片中淀粉和蛋白质含量降低。正常情况下,银杏叶片脯氨酸含量在22.21~30.08 mg/g,始终保持在较低水平,受涝后,银杏叶片中脯氨酸含量急剧上升。

摘  要：
Effect of flooding stress on hormones and cell solute in Ginkgo leaf was studied.The results showed the content of GA_(1+3),IAA and ZRs in leaf was obviously decreased under the flooding stress and their contents were separately 7.13,3.27,9.67 nmol/g at the(35~(th)) day after the flooding stress.With normal water supplied,the content of ABA in leaf was 4.74～8.57 nmol/g and the lower level was kept from beginning to end which content was separately 15.35, 18.41,20.56,22.63,and 24.91 nmol/g at the fifth,tenth,fifteenth,twentieth and twenty-fifth day after of the flooding stress.Under the flooding stress,its content was obviously increased and adding range appeared the tendency of going up with further stress was.The contents of total soluble sugar in water,reducing sugar,sucrose and proline wene increased in Ginkgo leaf.However the contents of starch and protein obviously decreased under the flooding stress.With normal water supplied,the content of proline in leaf was 22.21～30.08 mg/g,with lower level from beginning to end,but the content of proline in leaf was rapidly increased under the flooding stress.
