氯吡脲和多效唑配施对山药叶片一些生理特性的影响
Effects of forchlorfenuron and paclobutrazol combination on the physiological characteristics of yam leaves
摘要
Abstract
[Objective]This study aimed to understand the physiological characteristics of yam (Dioscorea opposita Thunb.) leaves after spraying the leaves with paclobutrazol and forchlorfenuron in order to provide theoretical basis for explaining the mechanism of forchlorfenuron and paclobutrazol combination on improving the yam tuber yield. [Method] Using the yam variety "Guihuai 2" as testing material, paclobutrazol combined with forchlorfenuron was applied to the yam during the in-tuber expansion period to determine the chlorophyll content, soluble protein, soluble sugar, MDA, proline content, and changes in POD activity in yam leaves and to conduct the regression equation and difference test analysis. [Result]Forchlorfenuron and paclobutrazol combination could improve the chlorophyll content and soluble protein content, reduce the soluble sugar content, strengthen the POD activity, increase the proline accumulation, and reduce the MDA content in yam leaves; out of the two fertilizers, the influences of forchlorfenuron were greater. The optimal application concentration for forchlorfenuron and paclobutrazol was 30 and 400 mg/kg, respectively. [ Conclusion ] Appropriate concentrations of forchlorfenuron and paclobutrazol could promote the chlorophyll synthesis and improve the protein accumulation and resistance ability in yam leaves.关键词
