    摘要:

    确定客观、合理的耐热性评价指标,评价不同品种蔬菜的耐热性强弱,对其耐热性机制的研究及耐热性品种的选育具有重要的意义。以不同耐热性的茄子品种为材料,测定苗期耐热性相关的生理生化指标,采用层次分析法(AHP)确定各耐热性指标的权数,通过模糊数学原理对茄子的耐热性进行综合评价分析。结果表明:热害指数、恢复指数、MDA含量、SOD活性、POD活性对耐热性影响较大,其权重依次为:0.2500、0.2500、0.1092、0.1092、0.1092。综合评价结果为茄子品种友谊一号耐热性最强,F-762茄子耐热性居中,古田紫长茄耐热性最弱,与田间自然高温鉴定结果一致,表明此方法对茄子苗期耐热性进行综合评价有较好的适用性,可用于大批量品种的耐热性鉴定。

    Abstract:

    Determining objective, reasonable heat tolerance evaluation indexes, and evaluating heat tolerance of different cultivars vegetables, which are of great significance to the research on heat tolerance mechanism and the breeding of heat tolerance. Different heat tolerance eggplant cultivars were used to determine physiological and biochemical indexes in seeding stage. The heat tolerance of eggplant seeding was comprehensively evaluated by using fuzzy mathematics theory. Using the analytic hierarchy process (AHP) to determine the weights of heat tolerance indexes. The results showed that heat injury index, recovery index, MDA content, SOD activity and POD activity had the greatest effect on heat tolerance. The weights were 0.2500, 0.2500, 0.1092, 0.1092 and 0.1092. According to the result of comprehensive evaluation, the heat tolerance of YouYiYiHao was the strongest, followed by F-762, and GuTianZiChangQie was the weakest. The results were consistent with those assessed in open field of natural high temperature. It showed that this method had a better applicability of comprehensive evaluation on eggplant seeding heat tolerance, which can be used for identification of heat tolerance in mass cultivars.
