Effects of Different Storage Conditions on Rooting and Shooting Performance of Grapevine (Vitis Vinifera L.) Cuttings in Hydroponic Culture System

Abstract

The shortfall in grapevine planting materials urged the researchers to enhance rapid propagation techniques with successfully storing the propagation materials such as rootstock and scion canes. The present study was conducted to assess the effects of different storage conditions (cold storage room at 1 °C plus 80-90% relative humidity and sand medium in open area) on rooting and shooting performance of cuttings of seven grapevine cultivars. For assessments, a hydroponic culture system was established in which the cuttings were rooted. Investigations on the cuttings prepared from the canes sampled at 6th, 7th and 8th months of the storage times showed that cold storage room significantly maintained the quality of canes with better callusing, rooting and shooting features. Storage at cold room can be recommended for long term storage, while dipping the canes in damp sand medium can be considered for a short time around a few months keeping of grapevine canes. Grapevine cultivars exhibited slight variation in response to both storage duration and storage conditions.
