Study on Sensitive Period of Floral Bud Morphological Differentiation in Sweet Cherry

doi:10.7668/hbnxb.2011.S1.058

Abstract

Abstract: The study taken sweet cherry hongdeng(Prunus avium.L.var.Hongdeng)as the materials,researched sensitive period of sweet cherries bud form in high temperature.The reasults showed that,the sensitive period of Sweet cherry floral bud differentiation in summer was Sepal primordia and Petal primordia.In high temperature treatments,double pistil in the following year was higher than other proceduces,just for Sepal primordia and Petal primordia,double pistil rate could reach 26.6%.Besides,each double pistil rate by high temperature treatment was higher than the control rate.

Key words: Sweet cherry, Floral bud differentiation, Double pistil, High temperature
