Abstract
Micropropagated plants of Actinidia chinensis Pl. with a height of about 5 cm, 2 expanded leaves, and 2-3 roots were successfully hardened by using a polyethylene tunnel in a glasshouse. The hardening was possible from September to January. The best results were obtained in November and December, with a recovery of 70.8% and 81.5%, respectively. The rooting of woody cuttings was achieved by treating them with a solution of IBA (1000 ppm for 24 h) and planting them under the same conditions to compare their growth with the micropropagated ones. Fresh and dry weights of roots and shoots were evaluated after 11 months of growth under nursery conditions. Micropropagated plants were between 11 to 14 times larger than those produced by the rooted cuttings.
