Abstract:
Taking seeds of Allium mongolicum with different storage years as test materials,the different concentrations of rare earth cerium,lanthanum chloride,yttrium chloride and chloride on storage 2 years and 5 years of A.mongolicun Regel seeds in seed handling,vigor index,activity of antioxidant enzymes,superoxide anion (O?2),malondialdehyde (MDA) and vitamin C content were measured,different treatment on A.mongolicun Regel seeds germination and physiological and biochemical characteristics,the influence of improving the utilization rate of seed were cleared, in order to provide theoretical basis for germplasm resources preservation.The results showed that different concentrations of agents had different germination effects on A.mongolicun Regel seeds,and low concentration treatment could promote seed germination,among which 400 mg? L-1 cerium chloride treatment had the best germination effect on A.mongolicun Regel seeds.Under the storage temperature of 20 ℃,the antioxidant enzyme activity of A.mongolicun Regel seeds was the highest;under the storage temperature of 50 ℃,the production rate of O?2 and MDA content under the treatment with cerium chloride were significantly decreased compared with the control group.The content of vitamin C at 35 ℃ and 50 ℃ ceriumion was higher than the control.
