Abstract
本试验对甜高粱M-81E品种离休再生体系进行优化,以种子发芽后的芽基部为外植体,对种子灭菌、愈伤组织诱导和芽根分化的条件进行了初步优化。结果表明:种子用75%的乙醇灭菌2min,然后用0.1%的升汞灭菌15min的灭菌效果较好;MS+4.0mg/L 2,4-D+0.1mg/L KT+1.38g/L脯氨酸+500mg/L水解酪蛋白+30g/L蔗糖+1%琼脂的培养基适合愈伤组织的诱导;MS+0.5mg/L 6-BA+1.0mg/L IAA+500mg/L水解酪蛋白+30g/L蔗糖+1%琼脂的培养基适合芽分化;1/2MS+3mg/L IBA+500mg/L水解酪蛋白+15g/L蔗糖+1%琼脂的培养基适合生根。
