甘薯抗旱鉴定及旱胁迫对甘薯叶片生理特性的影响
为挖掘抗旱甘薯基因资源,为甘薯抗旱育种及种植区域的拓宽提供科技支撑。本试验以全国各育种单位近年来选育的27个甘薯品种（系）为试验材料,在蒸发量远大于降雨量的新疆,设置正常灌水和干旱胁迫2个处理,采用抗旱指数法,对品种抗旱性进行鉴定评价。结果表明,根据抗旱指数及旱胁迫下鲜薯产量表现,筛选到抗旱指数高且产量高的种质材料6份（商薯9号、徐薯22、川薯20、湘薯15等）,并且抗旱性好的品种随着旱胁迫时间的持续,具有较高的脯氨酸（Pro）含量、过氧化物酶（POD）活性、较低的丙二醛（MDA）含量;在本试验中,各品种抗旱指数与叶片Pro含量呈极显著正相关（r=0.83）,与叶片POD活性呈显著正相关（r=...
