Preliminary Study on Nitrogen Metabolism in Sweet Cherry during Flower Bud Differentiation Period

doi:10.7668/hbnxb.2009.S1.047

Abstract

Abstract: With Rainier sweet cherry as materials,the dynamic changes of nitrogen nutrition contents and related enzymeactivity of nitrogen metabolism in different fruit branches of sweet cherry during flower bud differentiation periodwere determinated,and the relations between nitrogen metabolism and flower bud differentiation process were analyzed.The main results showed that the trend of nitrogen metabolism in different fruit branches of sweet cherry during flower buddifferentiation period were similar,of which the nitrogen metabolism of leaves in cluster fruit spurwas vigorous and corollaprimordium differentiation period was the strongest period for nitrogen metabolism during flower bud differentiation process.

Key words: Sweetcherry, Flowerbuddifferentiation, Nitrogenmetabolism
