| 摘 要： | 研究了极细链格孢蛋白激发子对湘杂棉3号主要生理特性和产量的影响,探讨抗虫杂交棉高产措施的生理机制,为高产栽培提供理论依据。分析极细链格孢蛋白激发子对棉花生理特性的影响。结果表明,在湖南气候条件与栽培技术体系下,细极链格孢菌蛋白激发子(PEAT)能显著提高棉花叶片光合速率,果枝叶叶绿素含量,同时提高了叶片可溶性蛋白质、可溶性糖含量,增强棉花生理机能;从生理生化活性来分析,极细链格孢菌蛋白激发子诱导后SOD、POD及MDA含量均有不同程度的变化,SOD、POD活性增强,而MDA活性降低,能起到延缓植株衰老的作用;从产量分析来看,极细链格孢菌蛋白激发子诱导后,显著提高单铃重、棉花产量,浸种+幼苗期喷施+现蕾期喷施+初花期喷施处理产量为1 781.44 kg/hm2,浸种+幼苗期喷施+现蕾期喷施处理产量为1 767.61 kg/hm2,比清水对照分别高出43.7%、42.5%,达到极显著水平。说明极细链格孢蛋白激发子能增强抗虫杂交棉生理机能、延缓棉株衰老、提高产量。
