Overwinter Storage of Walker Poplar Cuttings

Abstract

Rooting of cuttings was 82% after overwinter storage at -2OC, 73% after + 2OC storage, and only 60% after being heeled-in outdoors. Budbreak after planting was earliest for the heeled-in cuttings and latest for those refrigerated at -2OC, but length of the subsequent top growth was similar for all storage treatments. ResumeDes boutures de peupliers de Walker, apres avoir hivernb les unes en entrep6t a des temperatures de -2°C ou de +2OC et les autres en jauge a I'exterieur, ont eu les taux d'enracinement respectifs suivants: 82%, 73% et 60%. Le debourrage apres planification fut le plus precis chez les boutieres en jauge et le plus tardif chez les boutieres entreposees a -2°C. L'elongation subsequente de la pousse terminale a ete cependant similaire quelque soit le mode d'hivernage.

Role of Cold Storage in Rooting of Stem Cuttings: A Review

“…On May 23, the cuttings were planted in a nursery. The cuttings stored at -2°C showed the best rooting (82%), and 73% for those stored at 2°C, but heeled-in resulted in the lowest rooting (60%) [19]. In the continuation of the studies were conducted on cold storage of hardwood cuttings of chestnut, it was reported that 4 months of storage at 4°C from December to April was favourable to form root in the cuttings treated with 4000 mg.L -IBA before storage.…”
