Comparison of Photosynthetic Characteristics Among Three Paeonia lactiflora Cultivars
摘要
Abstract
The LI-6400 Portable Photosynthesis System is used to determine diurnal photosynthetic changes,light-response curves and CO2-response curves of different species in three Paeonia lactiflora varieties,The result indicates that diurnal changes of net photosynthetic rates (Pn) in leaves of the three cultivars presented a typical bimodal curve and had ‘midday depression’ phenomenon;According to the light and CO2 response curve can be obtained Huangjinlun than the other two species of photosynthetic ability is stronger,Yangfei bathing has a better response. CO2 concentration on the effect of Pn value is higher than that of PAR,increase Pn value is mainly affected by CO2 supply constraints,therefore,CO2 enrichment can improve the net photosynthetic rate of Paeonia lactiflora.关键词
