摘要:
为探究贮藏时间对皮、裸燕麦种子萌发特性和细胞组织结构的影响,本试验以皮燕麦‘陇燕3号’种子和裸燕麦‘白燕2号’种子为材料,研究两种不同燕麦种质种子经贮藏2、4、6和8年后,种子发芽指数、活力指数、芽长、根长和电导率的变化情况,并采用石蜡切片法和透射电镜法制片,观察比较贮藏时间对皮、裸燕麦种子解剖结构及种胚细胞和线粒体超微结构的变化规律及差异。结果表明:在贮藏过程中,2个燕麦种质种子发芽指数、活力指数均有所下降,电导率升高,与‘白燕2号’相比,‘陇燕3号’种子活力变化更稳定。随着老化程度加深,燕麦种子解剖结构发生变化,糊粉层细胞水解,老化燕麦种子种胚细胞与线粒体超微结构受到严重损伤,表现为:种胚细胞内脂肪体出现降解现象;线粒体的结构发生损坏、出现空泡化并解体;细胞核结构不清,核仁消失,核边缘皱缩,染色质浓缩。
