Abstract
4-year-old Nectarine(Prunus persick var.Nectarina Maxim) was used as test material in this experiment.The effects of foliar application KH2PO4(0.3%) on the photosynthetic characteristics and quality of nectarines in greenhouse were studied.The results showed that: after spraying KH2PO4(0.3%) on the leaves,light saturation point(LSP) of nectarine increased,light-saturated photosynthetic rate and the apparent quantum yield(AQY) increased,but light compensation point(LCP) decreased.CO2 compensation point(CCP) decreased,while the CO2 saturation point(CSP),CO2 saturated photosynthetic rate and carboxylation efficiency(CE) increased;the curves of net photosynthesis of treatment and control were double-peak.Daily average photosynthetic rate was obviously improved after spraying KH2PO4 on the leaves.Sprayed KH2PO4 on the leaves could also increase soluble sugar content and ratio of sugar to acid,but it had little effect on titratable acidity and vitamin C content.
