摘　　要：以2a生本溪山樱实生苗为试材,研究了局部NaCl处理对本溪山樱生理生化指标的影响。结果表明:采用0.4%NaCl对本溪山樱实生苗根系进行局部处理,其根系活力降低,叶绿素含量降低,光合作用受到抑制;MDA含量、POD、CAT、SOD活性、Na+、Cl-元素含量升高,K、Mg、Fe、Zn、Mn离子的吸收被抑制,进而对本溪山樱植株的生长发育产生了影响。Physiological-biochemical characteristics of 2-year-old Cerasus sachalinensis seedling were studied in open-field after local root NaCl treatment.The results showed that with the treating of local root 0.4% NaCl in C.sachalinesis,the root activity decreased,the contents of chlorophyll and photosynthesis were inhibited,the activities of POD,CAT,SOD and MDA content increased,the absorption ability of Na and K increased,and the absorption ability of K,Mg,Fe,Zn and Mn was inhibited,which affected the growth and development of C.sachalinesis.
