小黑麦是小麦和黑麦之间人工合成的新型作物,不仅产量潜力高、营养品质好、粮饲兼用、而且对不良环境有很好的适应性,近年主要在国内外高寒地区扩展种植。小黑麦抗逆性的研究目前主要集中在抗寒、抗病、耐盐碱、耐酸、耐瘠薄等方面,对其抗旱性的研究报道很少。 本研究选用26份小黑麦材料,在甘肃河西高海拔地区(海拔2400~2500m)旱地和灌溉条件下(水、旱地各两点),采取和小麦对比的办法,进行了小黑麦重要农艺指标对环境敏感性和抗旱生态适应性方面的研究,结果表明:

玉米抗病基因工程被认为是防治玉米病毒病的有效途径。克服玉米幼胚培养对基因型的依赖,提高玉米愈伤组织再生能力是玉米基因工程的基础。本研究从优化玉米幼胚培养遗传转化受体系统和抗病毒基因PAP的转化两个方面进行研究。以15种基因型的玉米为试验材料,通过对玉米幼胚进行变温处理显著提高了愈伤组织诱导率和整齐度,提高了愈伤组织质量;通过在分化前对愈伤组织进行干燥处理48h、震荡洗涤48h+干燥处理48h可以普
