Abstract:In this study,the effects of germanium on the growth,photosynthesis and oxidation resistance to salt stress of garlic cultivar ‘Jinsuan No.2’ seedlings were detected.The garlic seedlings were treated by 150 mmol· L-1 NaC1 and sprayed by 0.60 g· L-1 germanium solution.The results showed that after sprayed by 0.60 g· L-1 germanium solution,the height and root length of garlic seedlings under salt stress increased by 39.6% and 34.8%,the chlorophyll and net photosynthetic rate in garlic leaves under salt stress were increased 1.46 and 1.57 times.The oxidation resistance of garlic roots to salt stress was improved after the addition of 0.60 g · L-1 germanium.The contents of MDA and H2O2 were significantly decreased by 21.9 % and 19.6%.The activity of SOD,POD,CAT and APX were increased to 1.42,1.27,1.49 and 1.43 times of that under salt treatment.These results indicated that the 0.60 g· L 1 germanium enhanced the garlic growth,photosynthesis and oxidation resistance under salt stress.
