割手密(Saaccharumspontaneum L.)是现代甘蔗品种十分重要的野生型原始种亲本,主要用于品种的抗性、适应性和产量的改良。我国不仅是割手密的起源中心之一,也是割手密重要的多样性分布中心之一,富含丰富多样的割手密资源类型,即有八倍至十六倍等各种倍性割手密还有非整倍性割手密。百余年的甘蔗遗传育种历史表明,不同倍性割手密资源的利用,开辟了甘蔗杂交育种的历史,改良了甘蔗品种的抗性、适应性和产量,推动了世界甘蔗产业的快速发展。目前,国家甘蔗种质资源圃保育了较多的不同倍性割手密资源,但对它们的利

油菜是我国唯一的冬季油料作物,也是植物蛋白的重要来源。我国90%油菜分布在长江流域。尽管该区降雨较充沛,但全年降水并不均匀,季节性干旱频繁发生,给油菜的产量和品质带来很大的影响。本研究以甘蓝型油菜品种秦优7号(B.napus cv.Qinyou7)苏油10号(B.napus cv.Suyou10)为材料,通过盆栽试验研究了干旱胁迫对油菜苗期及蕾薹期生理特征和产量的影响,并通过叶面喷施氯化胆碱,探究
