以科棉1号棉花品种为材料，于2006、2007年在江苏南京（长江流域下游棉区）设置播期（4月25日、5月25日）和生长调节剂（6-BA、ABA）试验，研究低温条件下，外施6-BA、ABA对棉铃及棉纤维发育的影响及其生理机制.结果表明：常温和低温条件下，6-BA处理均能使相应部位棉铃铃质量增加、纤维品质提高；ABA处理在常温条件下会导致品质下降，而在低温逆境条件下可使纤维品质下降幅度减小；6-BA显...
用BA5、20、50mg/1的0.1%吐温-80溶液田间喷施大麦植株上部的功能叶，以喷水和喷0.1%吐温-80作为双对照，研究其对大麦花药培养的影响，结果表明：(1)喷施0.1%吐温-80可提高花粉愈伤组织诱导率，喷施BA 5mg/1的0.1%吐温-80可进一步提高愈伤组织诱导率。(2)喷水和喷吐温-80的，其愈伤组织只分化白化苗，分化率分别为22.2%和60%；喷BA 5mg/1的没有明显降低白...
