Abstract

Abstract: 14-year-old loquat cultivar（Changqi Zaosheng）that grew in Ankang of Shaanxi Province were used as experiment materials to study the physiological changes at young fruit stage under different moisture conditions in North-cultivated-marginal area. Irrigating each tree with different amount（0，10，20，30，40 kg）started from the end of August，2013（budding stage），and once per month. The sample of leaves and young fruits was gathered in the end of January，2014 to measure physiological indicators. The result showed that the content of chlorophyll and soluble protein content decreased after the first rise，PAL activity and content of MDA and SS decreased，Pro content and SOD activity increased after the first fall with increasing irrigation amount；There was no significant change on relative conductivity. Research suggested that 30 kg maintained soil moisture at about 22.2% is ideal for loquat growth in North- cultivated-marginal area.

Key words: loquat, moisture condition, young fruit stage, physiological indicators, resilience
