doi:10.3321/j.issn:1000-7091.2004.01.021

Abstract

Abstract: Fenghua 1,the new variety of peanut for high yield field,was used in this study.50% peg or 50%leaf in plant are removed artificially in polding phase,natural plant is control.Although leaf decreaseun hecompensated a little by the inreusing photosynthesis rate of single leaf and LAI high increasing rate,hlorophylldecomposes quickly and its content decreases,which accelerate the senescence of plant.

Key words: Peanut, Sourcsink ratio, Physiologicalaracter, Drymatter accumulation, Peanut yield
