以小金海棠、山定子为试材，研究了不同温度处理对二个苹果基因型铁离子吸收动力学特性的影响。结果表明：小金海棠、山定子幼苗对铁离子的吸收均符合Ｍｉｃｈａｅｌｉｓ－Ｍｅｎｔｅｎ离子吸收动力学规律，除基因型外，离子吸收动力学参数还受到介质温度的影响；介质温度、介质供铁水平均影响幼苗的铁吸收速率及铁吸收总量。在相同条件下，小金海棠比山定子有较大的铁吸收速率和铁吸收总量。与山定子相比，小金海棠对铁离子的亲和力较高，吸收能力较强，属于铁高效苹果基因型。
The effects of different temperature treatments on the kinetic characteristics of iron absorption of two apple genotypes were studied using the small golden crabapple and the rhizome. The results showed that the absorption of ferric ions of M. officinale and A.sinensis seedlings all accorded with the Michaelis-Menten ion absorption kinetics. Besides the genotypes, the kinetic parameters of ion absorption were also affected by the temperature of the media; the temperature of the media and the level of iron supplied by the media Iron absorption rate of seedlings and total iron absorption. Under the same conditions, the small gold Begonia than the mountain stator iron absorption rate and the total iron absorption. Compared with the mountain statues, the small gold Begonia ferric ion affinity higher absorptive capacity, belonging to the iron-efficient apple genotype.
