Studies on the Dynamic Variation of Mineral Element Content in Leaf during Flower Bud Differentiation Stage of Apricot

LI Li-hong et al(Department of Bioengineering,Zhengzhou College of Animal Husbandry Engineering,Zhengzhou,Henan 450011)  
The study was to reveal the mechanism of pistil dysplasia of apricot.The content dynamic changes of Fe,Mn,Zn,Mg,N and K in leaves of 6 apricot varieties in the flower bud differentiation stage were determined to study some physiological and biochemical changes during the flower bud differentiation stage of apricot tree.In the leaves of apricot during the flower bud differentiation stage,there was significant difference in Fe,Mn, Mg and K contents among different varieties,the difference in Zn content was obvious among different dates and no significant difference in N content either among different varieties or among dates.There was extremely significant difference in Zn content among different flower bud differentiation stages in apricot and significant difference in Fe,Mg,Mn and K contents among varieties with different abortion rates.These kinds of mineral elements were one of factors affecting growth quality of apricot flower bud.The study supplied theoretical basis to reveal the abortion mechanism of the apricot pistil.
