title: [Effect of environmental factors on photosynthetic physiology and flavonoid constituent of Scutellaria baicalensis].
abstract: 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.
