本試驗目的調查在葡萄柚發育最後四個月,葉內無機養分濃度。由於葉齡逐漸增加情形下,葉內鎂及鉀濃度降低,鈣及鐵濃度增加,氮,磷,錳,鋅及銅濃度有稍減趨勢。The mineral nutrients in the late fruit developed stage of grapefruit leaves over 4 monthes are reported here.\ud Concentration of magnesiun and potassium tended to decrease with the age of leaves, whereas the concentration of calcium and iron increased until mid winter. Nitrogen, phosphorus manganese, copper and zinc concentration decreased slightly during the fruit developed stage
