【摘要】 低温增加了IAA含量,但降低了花器官含量与生长点含量的比值,细胞分裂素含量变化表现与IAA相似,赤霉素含量变化复杂,ABA含量增加;单性结实品种其ABA、细胞分裂素含量在低温下具有较高的花器官和生长点比值且大于1,赤霉素和生长素含量该比值也高于其他品种。更多还原

【Abstract】 Low temperature increased IAA content, but decreased the ratio of flower to apical point ZR was similar to IAA. The change of GAs was complicate, ABA content increased;Parthenocarpical cultivar had a higher ratio of flower to apical point which more than one at ABA and ZR, the ratio was the highest among cultivars at GAs and IAA.更多还原
