| 摘 要： | 以储良龙眼为试材,通过分析低温诱导、氧化胁迫、自然低温+药剂处理龙眼成化过程中氧化损伤各指标变化,研究龙眼成花和氧化胁迫之间的相关性。结果表明,氧化胁迫有利于龙眼成花。对顶芽和叶片活性氧、抗坏血酸和丙二醛(MDA)含量的检测结果也表明,氧化胁迫诱导龙眼成花的同时,也导致了龙眼树各组织活性氧的累积,且抗坏血酸抑制龙眼成花,MDA促进龙眼成花。因此认为活性氧与龙眼成花呈正相关。

| Abstract: | Low temperature induced, oxidative stress, natural low temperature combined with medicament spraying were used to study the correlation between longan-flowering and oxidative stress. Results indicated that oxidative stress induced longan flower, and led to the accumulation of reactive oxygen in parts of longan tree organizations, while ascorbic acid inhibited longan flower, MDA promoted longan flower. It confirmed there was a positive correlation between longan flower and active oxygen. |
