Abstract:
The dynamic variation and geographical variation of single plant leaf biomass and secondary metabolites′ contents in leaf of different Hippophae rhamnoides provenances were studied.The 10 Hippophae rhamnoides provenances were comprehensively evaluated by subordinate function method，in order to select comprehensive excellent leaf-used provenances.The results showed that there were significant geographic variations in leaf biomass and secondary metabolite contents in leaf of 10 Hippophae rhamnoides provenances.Total flavonoids content in leaf of 10 Hippophae rhamnoides provenances reached the peak in July，and triterpenoid content reached the peak in September and polysaccharide content reached the highest in June.It provided a basis for determining the optimum utilization time of different secondary metabolites in leaves.Based on single plant leaf biomass，secondary metabolite contents in leaf and single plant secondary metabolites yield during the period of highest contents of secondary metabolites，selection of special utilized leaf-used provenances were selected by subordinate function method.The top 3 ones of the provenances with high yield and high total flavonoids contents were Guyang，Laobaigou，Longfenggou；the top 3 ones of the provenances with high yield and high triterpenoid content were Laobaigou，Guyang，Boketu；the top 3 ones of the provenances with high yield and high polysaccharide content were Laobaigou，Guyang，Longfenggou.Based on single plant leaf biomass，secondary metabolite contents in leaf during the period of each index，comprehensive excellent leaf-used provenances were selected by subordinate function method.The top 3 provenances were Laobaigou，Guyang，and Etuoke.In summary，no matter special utilized type or comprehensive excellent type，Guyang and Laobaigou ranked the top two，which showed single plant leaf biomass of them large，secondary metabolites contents high and secondary metabolites yield high，so they were suitable as fine leaf-used pronvences.
