| 摘 要： | 以筛选的自毒物质忍耐型(01 号)和自毒物质敏感型(02 号)杉木无性系为试验材料, 采用胁迫试验分析邻羟基苯甲酸对2 个不同化感型杉木无性系内源激素含量的化感效应。研究结果表明, 邻羟基苯甲酸对不同化感型杉木无性系ABA 含量表现为促进效应, 其中对01 号杉木无性系的促进效应大于02 号; 邻羟基苯甲酸对不同化感型杉木无性系IAA、GA3 含量表现为抑制效应, 胁迫后期邻羟基苯甲酸对02 号无性系GA3 含量的抑制效应较01 号强, 2 个无性系间IAA 含量的抑制效应差异不明显; 邻羟基苯甲酸对不同化感型杉木无性系ZR 含量的化感效应表现为胁迫第20 d 达到抑制效应高峰期, 随后抑制作用下降, 邻羟基苯甲酸对02 号无性系ZR 含量的抑制效应强于01 号无性系。 |

| Abstract: | Autotoxins-tolerant clone (No. 01) and autotoxins-sensitive clone (No. 02) of Chinese fir were used to determine allelopathic effects of salicylic acid on endogenous hormone content of different Chinese fir clones. The results showed that salicylic acid promoted ABA concentration, and it was much more in clone No. 01 than in clone No. 02. Though salicylic acid lowered IAA and GA3 content in both clones, the effect was greater for GA3 in clone No. 02 than in clone No. 01 at the later stage of the experiment. However, inhibitory effects of salicylic acid stress on IAA were not significantly different for both clones. Inhibitory effect of salicylic acid stress on ZR increased with stress time and peaked at 20 day into the experiment for both clones, and it then dropped, with a stronger effect on clone No. 02 than clone No. 01. |
