Abstract:
Taking five-year-old Lonicera hypoglauca Miq. as test materials,the leaves of Lonicera hypoglauca Miq. were treated by the different concentrations of oligo-chitosan (600 mg/L,800 mg/L,1 000 mg/L,1 200 mg/L),then the leaves photosynthetic parameters and the chlorophyll fluorescence parameters were measured in 5-30 days,the effect of oligo-chitosan on the photosynthetic characteristics of the leaves and the quality of leaves,flowers,stems in normal conditions were studied.The results showed that 600 mg/L treatment had little effect on photosynthesis and chlorophyll fluorescence characteristics of leaves.800 mg/L,1 000 mg/L and 1 200 mg/L treatments had significant effect on photosynthesis and chlorophyll fluorescence characteristics of leaves,the net photosynthetic rate (Pn),stomatal conductance(Gs),intercellular CO2 concentration(Ci),transpiration rate(Tr),maximum photochemical efficiency of PSⅡ(Fv/Fm),photochemical quenching coefficient(qP) first decreased then increased,non-photochemical quenching coefficient(qN) first increased then decreased.1 000 mg/L treatments was more stable than 800 mg/L and 1 200 mg/L treatments.A certain concentration of oligo-chitosan could improve the photosynthetic characteristics of the leaves and enhance the medicinal ingredients of Lonicera hypoglauca Miq.
