本文阐述了NAA诱导乙烯产生和乙烯利促进插穗生根效果的研究结果。在NAA浓度为10～500ppm范围内处理毛白杨嫩枝插穗,明显促进乙烯释放。在10～100ppmNAA处理中,乙烯释放量随浓度加大而增加,到500ppmNAA则略有下降。NAA处理结束后到乙烯释放之间,有一停滞期,约2～4h。试验证明,将插穗切成小块,增加伤口数量,不能明显引起乙烯释放量增加。乙烯可促进硬枝茎插穗上的潜伏根原基萌发,加速不定根的产生。

本文选择毛白杨和加拿大杨这两个插穗生根难易程度不同的树种为研究对象。试验再次证明,适度的萘乙酸(NAA)处理可提高插穗生根率。它的最明显的作用是促进茎插穗沾药部分愈伤组织的产生。高浓度的NAA处理促使插穗中物质过多调运到正在生长的愈伤组织中。这不仅影响到嫩茎的生长,而且不利于细胞再分化为根原基,甚至产生生理毒害作用。NAA处理的效果因扦插时期而异。NAA处理可较迅速地引起乙烯的释放,可提高细胞质膜透性,提高呼吸强度。经NAA处理过的插穗,经过冷藏可提高插穗含水率和过氧化物酶活性。高浓度NAA处理更大地提高质膜的透性,使膜受到伤害,并使细胞失水。

冲动性购买涉及大多数消费者,是营销领域重点关注的问题。随着物质资源的不断丰富和各类新型文化潮流的影响,消费者对同一类型商品进行重复性冲动购买的情形日趋普遍,而相关文献对同类产品冲动性购买行为的研究则较少涉及。本研究采用眼动行为实验,从消费者不同趋近动机的积极情绪出发,基于自我控制资源有限性视角,探讨不同趋近动机积极情绪对消费者进行同类产品冲动性购买的影响。研究结果显示,不同趋近动机的积极情绪对消费者的注意范围存在影响。相对于低趋近积极情绪,高趋近积极情绪会增强消费者对同类产品冲动性购买意愿。同时,时间压力及金钱概念在不同趋近动机积极情绪与冲动性购买意愿间起调节作用。对于高趋近积极情绪的消费者,较大的时间压力与低丰富程度的金钱刺激会促进其进行冲动性购买行为。本文旨在为商家进行系列产品销售、增加商品销量提供指导与建议。
