摘要
探讨环境因子与光合作用对黄芩生长发育和活性成分含量的影响。观测黄芩花果期光合生理指标、黄芩黄酮类成分日变化,记录环境参数。采用通径分析和灰色关联度分析方法进行数据分析。结果表明,光合有效辐射(PAR),土壤含水量(SWC)是影响黄芩光合作用的重要环境因子。SWC,RH,Ca是影响黄芩苷含量重要环境因子,PAR,大气压力(Po),大气温度(Ta)是影响黄芩素含量的重要环境因子。为有针对性的开展环境因子调控,实现黄芩的优质高产提供理论依据。
To discuss the effect of environmental factors and photosynthesis on the growing of plant and the content of active components in Scutellaria baicalensis,the photosynthetic physiology index and diurnal changes of flavonoid constituent of S.Baicalensis were observed and tested in flowering and fruiting stages,and in the meantime environmental parameters were recorded.The obtained data were analyzed data by using path analysis and gray correlation analysis.The results showed that PAR and SWC were important environmental factors impacting on photosynthesis of S.baicalensis.SWC,RH and Ca were important environmental factors impacting on baicalin content.PAR,Po and Ta were important environmental factors impacting on baicalein content.
