早春麦田划锄对麦田土壤水分状况及小麦生长发育的影响
Effects of Intertillage Technology on Soil Water Status in Wheat Field and Wheat( Triticum aestivum Linn.) Growth and Development at Early Spring
摘要
Abstract
[Objective]This study aimed to investigate the effects of heavy-ion beam irradiation on the seed germination potential, survival rates, antioxidant enzyme activities and lipid peroxidation of sweet sorghum.[Method]The dry seeds were irradiated by 12C6* heavy ion beam with absorbed dose;0, 40, 80, 120, 160 and 200 Gy, respectively. Then, the seed germination potential, survival rates, antioxidant enzyme activities and lipid per oxidation of sweet sorghum were measured.[Result]Heavy-ion beam irradiation exhibited different influence on germination potential and survival rates. Germination rate showed a downward trend, but the corresponding survival curve of seedlings was saddle-shaped. The activities of SOD, POD, CAT and ASA-POD changed in different trends as well. The MDA content was increased with the increasing dose of irradiation, suggesting that high dose of heavy-ion beam irradiation enhanced the damage to membrane of sweet sorghum seedlings.[Conclusion]After being irradiated, germination potential and survival rates of sweet sorghum were decreased, and antioxidant enzymes activity greatly changed. This study laid the basis for further work on breeding and improvement of sweet sorghum irradiated by 12C6+ heavy ion beam.关键词
