接种深度对‘威芋3号'茎尖快繁成苗的影响

Effect of Inoculation Depth on Meristem-tip Rapid Propagation into Seedlings of 'Weiyu No.3'

以‘威芋3号'脱毒苗的茎尖为试材,研究不同接种深度对成苗时间、瓶苗素质、移栽成活率的影响,并对成苗综合素质量化积分。结果表明:6mm接种深度时,成苗时间最短,为14.67d,瓶苗茎粗、根系数、干重、移栽成活率、量化积分均达峰值分别为1.20mm、14.93条、1.73g、97.67%、80.49分。因此,6mm是‘威芋3号'茎尖快繁成苗的最佳接种深度。

Taking virus-free plantlets of'Weiyu No,3'as test material,and scissoring meristem-tip,then the seedling time,bottle seedlings'quality,survival rate of transplanting and quantitative integral on comprehensive quality of seedlings were researched.The results showed that inoculation depth was closely related to seedlings,with the 6 mm, seedling time was the shortest for 14.67 d;At the same time,stem diameter,root coefficient,dry weight,transplanting survival rate and quantitative integrals reached peak value for 1.20 mm,14.93 roots,1.73 g,97.67%,80.49 points respectively.Therefore,6 mm was the best inoculated depth on meristem-tip rapid propagation into seedlings of'Weiyu No.3'.
