- 摘要:
- 在抗寒锻炼期间，以梓楸、滇楸、灰楸3种楸树为材料，利用酶联免疫吸附方法（ELISA）测定其叶片内源激素IAA（吲哚乙酸）、ABA（脱落酸）、GA3（赤霉素）、ZR（玉米核苷）的含量。结果表明：抗寒锻炼期间，3种楸树叶片ABA含量基本上均呈上升趋势，其它3种激素含量变化趋势不一致。说明在抗寒锻炼期间，3种楸树的抗寒能力逐渐增加。
- Abstract:
- The present test was undertaken with three catalpa bungei leaves to find out the change of the three endogenous hormones such as ABA，GA3，IAA，ZR by Enzyme Linked Immunosorbent Assays (ELISA ).The result indicates that during cold hardening，the overall view，the ABA contents in the four Catalpa bungei were basically upward trends，the trends of the other three endogenous hormones were inconsistent.Cold resistance of three catalpa bungei increased during cold hardening.
