9个晚籼稻品种在红壤中的耐酸性鉴定及有关保护酶活性的变化

为了研究水稻耐酸特性,选择9个已在江西省推广的晚籼稻品种,分别在填入了水稻土和酸性红壤的水池中种植,测定了过氧化氢酶(CAT)、超氧化物歧化酶(SOD)、过氧化物酶(POD)等保护酶活性及丙二醛(MDA)含量等生理指标,考察了株高、产量等农艺性状。结果表明,不同品种生理指标存在差异。酸胁迫下CAT活性和MDA含量降低,SOD活性升高,POD活性无明显变化规律。MDA含量的变化与3种保护酶活性各自间均无明显关联,但可能受到它们的共同影响。酸胁迫下各品种农艺性状呈现不同程度的变异,POD活性、MDA含量与单株产量变异幅度显著相关,可以用于评价水稻耐酸特性。综合看来,天丰优6418、深优957和跃新...

Summary:为了研究水稻耐酸特性,选择9个已在江西省推广的晚籼稻品种,分别在填入了水稻土和酸性红壤的水池中种植,测定了过氧化氢酶(CAT)、超氧化物歧化酶(SOD)、过氧化物酶(POD)等保护酶活性及丙二醛(MDA)含量等生理指标,考察了株高、产量等农艺性状。结果表明,不同品种生理指标存在差异。酸胁迫下CAT活性和MDA含量降低,SOD活性升高,POD活性无明显变化规律。MDA含量的变化与3种保护酶活性各自间均无明显关联,但可能受到它们的共同影响。酸胁迫下各品种农艺性状呈现不同程度的变异,POD活性、MDA含量与单株产量变异幅度显著相关,可以用于评价水稻耐酸特性。综合看来,天丰优6418、深优957和跃新2号为具有较强耐酸特性水稻品种。

In order to research the acid tolerance of rice,nine late indica rice varieties having been commercialized in Jiangxi Province were screened out and planted in two pools filled with paddy soil and red soil respectively. Activities of protective enzymes including catalase( CAT),superoxide dismutase( SOD) and peroxidase( POD),and malindialdehyde( MDA) content were measured. The agronomic traits,such as plant height and yield,were investigated. The re
