基于“3414”模型对淹水胁迫下硝普钠、亚精胺和表油菜素内酯对两种丁香光合速率影响的研究
|
摘要
通过研究淹水胁迫下紫丁香Syringa oblata和小叶丁香Syringa m icrophylla的硝普钠、亚精胺和表油菜素内酯"3414"施用方案对光合速率的影响,建立不同的回归效应模型,探寻最适宜的喷施方案。结果表明两种丁香所有喷施处理的净光合速率,均比无喷施处理的对照要高。经回归分析,在此试验条件下,紫丁香淹水第6d,SN P、spd、EB R最佳施用量分别为0.13m m ol·L~(-1)、0.2m m ol·L~(-1)、0.75m g·L~(-1)。小叶丁香淹水第6d,SN P、spd、EB R最佳施用量分别为0.17m m ol·L~(-1)、0.36m m ol·L~(-1)、0.68m g·L~(-1)。
Study the "3414" model on sodium nitroprusside spermiden and epibrassinolide of Syringa oblata and Syringa microphylla under flooding stress on photosynthetic rate in order to find the most suitable spraying project and establish the different regression model. The result showed that all the spraying treatments increased the net photosynthetic rate of two Syringa under flooding stress to the control group. Through regression analysis, under the experimental condition, Syringa oblata flooded 6 days,SNP,spd,EBR best surueyed is 0.21mmol·L~(-1), 0.26mmol·L~(-1)and 0.27mg·L~(-1). Syringa microphylla flooded 6 days,SNP,spd,EBR best surueyed is 0.17mmol·L~(-1), 0.36mmol·L~(-1)and 0.68mg·L~(-1).
