摘 要:为了筛选出红颜草莓组培苗的炼苗最佳基质,以红颜草莓组培苗为实验材料,通过测量其成活率、株高、新叶数与鲜重等各项指标,研究草莓组培苗在不同基质中对组培苗炼苗效果的影响。结果表明,采用基质体积配比为草炭∶蛭石∶珍珠岩=1∶1∶1,草莓组培苗移栽成活率达100%,且草莓株高、新叶数与鲜重等各项指标均为最佳,幼苗生长发育健壮。

Abstract: The purpose of the experiment is to select the best substrate for the growth of strawberry cultivar ′Benihoppe′ tissue culture seedlings. In this paper, strawberry cultivar ′Benihoppe′ tissue culture seedlings were used as experimental materials to study the effects of different substrates on the growth adaptability of strawberry tissue culture seedlings by measuring their survival rate, plant height, number of new leaves and fresh weight. The results showed that the survival rate of Strawberry Tissue culture seedlings was 100%, the height of strawberry plant, that the number of new leaves and fresh weight were the best, and that the growth of strawberry seedlings was robust.

草莓是薔薇科(Rosaceae)草莓属(Fragaria)的多年生草本植物[1]。现代大果型的栽培草莓基本以凤梨草莓(Fragaria×ananassa Duch)为主[2],其中红颜草莓属于优秀凤梨草莓品种之一。早期草莓种苗的繁育主要是利用匍匐茎进行无性繁殖,但该方法繁殖系数较低、育苗品质较差,且繁殖过程中易传播危害草莓的病虫害,限制了草莓产业的发展[3]。近年来组织培养技术引入草莓的繁殖,有效保证了草莓品种的纯度,减弱病虫的危害。草莓组培苗的炼化是繁育过程中重要的一环,其炼苗成活率关系到组织培养技术在工厂化育苗的推广与应用,因此筛选草莓组培苗的生长基质具有重要意义。

本研究以红颜草莓组培苗为实验材料,设置不同比例的栽培基质,通过比较不同栽培基质中草莓组培苗的成活率、株高、新叶数与植株鲜重等数据,旨在对红颜草莓炼苗过程中生长的差异进行研究与探讨,为建立起完善高效的草莓组培苗炼苗体系奠定基础。……
