日本京都大学农学部对9种苹果砧木(下垂型圆叶海棠、M4、M7、M9、M11、M16、M26、M27及MM106)进行过耐盐性比较试验.将一年生的砧木压条采用土壤进行盆栽,在砧木生育期,使用浓度为0、20、40及80mM(毫克分子)的Na-Cl水溶液,每天浇灌,约30～60天.砧木叶片的受害程度,M4、M27、M11大,M16、M26较小.Cl和Na在所有砧木的叶片中均有所增加.圆叶海棠、
The experiment of salt tolerance of nine kinds of apple rootstocks (drooping lobular crabapple, M4, M7, M9, M11, M16, M26, M27 and MM106) was carried out by Department of Agronomy, Kyoto University, Japan. , Rootstocks in the growth period, the use of concentrations of 0, 20, 40 and 80mM (millimolar) Na-Cl aqueous solution, watering every day, about 30 to 60 days. Rootstock damage degree, M4, M27, M11 large, M16, M26 is smaller.Cl and Na in all the rootstock leaves have increased.Leucomesel,
