Abstract

Abstract: This study through analysis the effects of salt stress on growth,physiological and biochemical characteristics and quality of celery to provide theoretical basis of the selection of celery cultivars under salt stress.In this experiment,two celeries (Jingqin No.1 and Xiaqin)were treated by different NaCl solutions(0,30,60,90,120 mmol/L),and through pot experiment to study the effects of NaCl stress on the growth,physiological and biochemical characteristics and quality of celery.The results showed that the growth of celery was inhabited by NaCl stress.With the NaCl concentration increasing,height,fresh weight,dry weight gradually decreased,the activities of SOD,CAT and the content of MDA,chlorophyll in leaf gradually increased,but the activity of POD and content of soluble sugar increased firstly and then decreased.The Vc and fiber content gradually decreased with the salt concentration increasing.Under the NaCl stress,the growth,physiological and biochemical characteristics of Jingqin No.1 had smaller effect than Xiaqin,Jingqin No.1 had stronger NaCl stress tolerances ability.

Key words: Celery, NaCl stress, Growth, Physiological and biochemical characteristics, Quality
