Abstract: Jingdong chestnut,as high quality chestnut fruit,is the major nut fruit in Beijing region .However,there islittle information about mineral nutrition of the chestnut .We sampled leaves from both nutrition and fruit branches and analyzedthe concentrations of N,P ,K ,Ca ,Mg ,B,Zn,Fe ,Mn,Cu .The objectives included understanding the characters ofthese nutrient concentration and their seasonal changes,and supplying with fundamental data for further managing plantnutrition,enhancing yield and improving fruit quality .The results showed that the concentrations of P ,K ,Cu andMg weresimilar in the leaves from nutrition and fruit branches and changed little during plant growth .However,concentrations ofother mineral elements changed with plant development and leaves .In general,these nutrient concentrations increased withplant growth .Particularly,the concentrations of both Zn and Mn were of linear enhancement during plant growth .Theleaves of nutrition branch in fruiting period had higher contents of N,Zn and Fe,but lower B,than that of fruit branch .However,in whole growth season,the leaves in nutrition branch always contained lower Ca but higher Cu than that in thefruit branch .
