不同材料冬季贮藏魔芋原原种比较研究

Comparison of Three Storage Methods for Konjac Breeder's Seed during Winter

[目的]寻找冬季魔芋原原种安全贮藏的最佳材料。[方法]以当年收挖的魔芋原原种为试验对象,采用干沙、膨胀珍珠岩、牛皮纸包裹温箱贮藏3种不同的材料贮藏对比试验,通过对失水率、种芋新鲜程度、主芽萌动程度、病害发生率进行统计来考察不同材料贮藏对魔芋原原种冬季贮藏的影响。[结果]干沙贮藏的原原种外观新鲜、主芽健壮、颜色粉红、无病害、失水率12.7%,是魔芋原原种冬季安全贮藏的最适合材料。牛皮纸温箱贮藏法由于温度、湿度控制比较好,所以在失水率、种芋新鲜程度、主芽萌动程度、病害发生率诸方面表现较平均,如果有温箱等条件,也是可以采用的贮藏方法。[结论]研究表明,魔芋原原种冬季最佳贮藏材料是干沙,可以广泛推广应用。

[ Objective ] Konjac seed has always been the restriction factor of the development of konjac industry, and the storage method dur- ing winter will directly influence the quantity and quality of konjac seed the next year. [ Method] In this study, we use the konjac breeder＇ s seed we harvest in the present year as experimental subject to find out the best storage method of konjac breeder＇ s seed during winter by com- pare three different storage method. [ Result] After the comparison of water loss rate, seed fresh grad, the main bud sprout degree and disease incidence of all the three methods, the result indicated that the dry sand storage method is the best storage method of konjac breeder＇ s seed during winter and oven kraft paper storage method is also an acceptable storage method. [ Conclusion] It was concluded that dry sand storage method is the best storage method of konjiac breeder＇ s seed during winter which can be widely applied.
