摘要:
以2年生杜仲(Eucommia ulmoides)苗为试验材料,分别对其作A(正常生长)、B(水淹+喷清水)、C(水淹+喷水杨酸)、D(水淹+喷三唑酮)4种处理,研究水淹胁迫对杜仲苗的影响以及水杨酸、三唑酮对水淹杜仲苗的缓解作用。结果表明:淹水胁迫使杜仲出现叶斑、叶片脱落等症状,清水处理组25 d后2株死亡;而水杨酸和三唑酮处理组在一定程度上提高其抗性,但三唑酮处理的植株有明显的矮化现象;水杨酸和三唑酮处理的植株能缓解水淹胁迫下叶绿素和气孔导度的下降,因而提高了2年生杜仲苗净光合速率;水杨酸和三唑酮处理的Fv/Fm值高于清水处理组的值,有利于植株传递光合电子和所需的能量,在一定程度上保护了光合机构。
Abstract:
2-year Eucommia ulmoides seedlings from nursery in Tianmu, Zhejiang province were treated by normal growth (A), water logging + water spraying (B), water logging + salicylic acid spraying (C), water logging + triazolone spraying (D) in 2012. The result demonstrated that seedlings under water logging had symptoms of leaf spot leaf loss, 2 seedlings (B) even died 25 days later. Seedling of C and D had better growth, but that of D had evident dwarfing effect. The experiment showed that seedlings with salicylic acid and triazolone treatment had higher net photosynthetic rate and FV/Fm.
