【摘要】 以“丰香”品种为试材,MS为基本培养基,研究草莓玻璃化的克服措施,结果表明,在6-BA试验浓度范围内(1-3 mg.L-1),玻璃化率随6-BA浓度的增加而增加;40 g.L-1蔗糖,降低MS基本培养基中铵离子浓度,加入活性炭,采用透气膜封口在一定程度上均能使玻璃苗恢复正常.更多还原

【Abstract】 Cultured in vitro on MS medium supplemented with 6-BA,the strawberry variety "Tochiotome" showed increasing vitrification rate with increasing 6-BA concentration(1~3 mg/L).The addition of sucrose to the medium at 40 g/L helped to decrease the number of vitreous plantlets.The measures of decreasing NH+4 concentration in the medium,or adding active carbon to it,or sealing the bottle with a permeable film helped the vitreous plantlets change back to normal ones.更多还原
