Effects of Different Foliar Fertilizers on Flowering,Fruiting and Flavonol Glycosides Content in Epimedium pubescens
Objective:To study the effects of different foliar fertilizer sprays on flowering and fruiting and flavonol glycosides content in Epimedium pubescens.Methods:Two-year-old seedlings of E.pubescens were used as test materials.Five treatments were applied:0.1%potassium dihydrogen phosphate(T1),0.06%boric acid(T2),0.1%potassium dihydrogen phosphate+0.03%boric acid(T3),5%amino acid water-soluble fertilizer(T4)and water(CK).These were sprayed before budding,at the bud stage,and in full bloom.The effects of each treatment on photosynthesis,flowering,and fruiting,and the content of flavonol glycosides in leaves were analyzed.Results:Compared with CK,T1 treatment significantly increased the number of flowering branches,seed yield,and total flavonol glycosides;T2 treatment increased the number and length of flowering branches,seed yield,thousand-seed weight,and the content of epimedin A and epimedin B in leaves;T3 treatment increased the number of flowering branches and seed yield,but was not conducive to the accumulation of flavonol glycosides;T4 treatment increased the number of flowering branches,seed yield and total flavonol glycoside.Conclusion:Rational application of foliar fertilizer can promote flowering and fruiting and increase the content of flavonol glycosides.Among the treatments,boric acid is most effective in promoting fruiting,while potassium dihydrogen phosphate and amino acid water-soluble fertilizers have a positive effect on growth and flavonol glycosides accumulation.The results of this study can provide a reference for the seed production of E.pubescenum and the formulation of fertilization programs for the targeted cultivation of medicinal materials.
