为探究外源赤霉素(GA)和褪黑素(MT)对盐、碱和干旱胁迫下白三叶(Trifolium repens)种子萌发、幼苗生长及抗氧化酶的影响,本试验以白三叶‘瑞文德’为试验材料,设置不同浓度(5,10,20,50 mg·L^(-1))GA和(1,2,5,12 mg·L^(-1))MT的处理,测定了3种胁迫下种子萌发、幼苗生长及生理指标。GA和MT可有效缓解盐、碱和干旱胁迫对白三叶种子萌发及幼苗生长的抑制作用,且随着外源物质浓度的升高,各指标呈先升后降的趋势。其中,20 mg·L^(-1)GA显著促进了盐胁迫下白三叶的种子萌发;5 mg·L^(-1)MT显著增加了干旱胁迫下白三叶的胚根长和鲜重;20 mg·L^(-1)GA显著提高了碱胁迫下白三叶的SOD、POD和CAT活性。通过隶属函数分析得出20 mg·L^(-1)GA浸种缓解盐和碱胁迫效果最佳,5 mg·L^(-1)MT浸种缓解干旱胁迫效果最佳。因此,在盐、碱和干旱胁迫条件下,使用20 mg·L^(-1)GA或5 mg·L^(-1)MT浸种能够显著促进白三叶种子萌发和幼苗生长。

针对哈里斯鹰优化算法(HHO)易陷入局部最优和收敛速度慢的问题,提出一种基于精英引导的改进哈里斯鹰优化算法(EHHO)。首先,引入精英反向学习,以精英中心为对称中心进行反向学习来优化种群结构,增强算法跳出局部最优的能力;其次,引入精英演化策略,以精英个体为主体进行基于高斯随机突变的演化来提升种群质量,加快算法收敛速度;最后,引入自适应机制,动态调整精英演化策略中2种演化方式的选择概率,以提升算法稳定性。为验证改进算法的有效性,选取15个基准函数进行仿真实验。实验结果表明,改进算法在寻优性能和鲁棒性上均有明显提升,在优化算法中具有一定竞争力。
