铁在苹果树器官中的定量研究
Study of Iron Content in Different Organs of Apple Tree
摘要
Abstract
Plant analysis of mature apple tree indicate:fresh weight of fruits,leaves,branch & trunk and roots accounted for 42.09%,6.33%,38.81%,12.77%,respectively.The fresh weight of fruits was biggest.The fresh weight of total plant was 207.90 kg.Dry weight of fruits,leaves,branch & trunk and roots accounted for 19.51%,6.45%,57.30%,16.75%,respectively.The dry weight of branch & trunk was biggest.The dry weight of total plant was 84.31 kg.The water weight of plant arrived at 123.55 kg.Iron concentration in diameter ＜0.5 cm root was highest among other organs,arriving at 257.51 mg/kg.Iron concentration of leaves that was sensitive to iron stress arrives at 214.09 mg/kg.The iron concentration was the lowest in fruits:18.27 mg/kg.The total iron content of plant was 4 915.78 mg.Iron weight in leaves,fruits,roots and branch & trunk was 1 165.26,300.72,1 500.38 and 1 950.43 mg,account for total iron content 23.70%,6.12%,30.52% and 39.66%,respectively.关键词
