Abstract

Every year large amounts of grapes are stores in normal and cold rooms to offer off-season of grapes to the market which based on several reasons their quality and weight greatly decreases. Therefore, in order to decrease the post harvest losses of grapes and selection of suitable cultivars for long time storage, this study was conducted in two experiments, one in a factorial experiment based on randomized complete design (CRD) in three replications with two factors including cultivars (Sefide bidane and Qzel Ozum), and packaging type (one sulfur pad with perforated bag, ½ sulfur pad with imperforated bag, without sulfur pad with perforated bag, without sulfur pad with imperforated bag, without sulfur pad and without bag) and the other in a randomized complete design (CRD) with five packaging treatments and three replications for Rasha cultivar. Grape bunches were harvested and transferred to cold storage. To study the effects of treatments, some traits including bunch and berry shriving, bleaching, fungal rot (%), bunch appearance and taste were measured. Results showed that using one sulfur pad with perforated bag and ½ sulfur pads with imperforated bag treatments controlled fungal rots and bunch and berry shriving, and preserve bunch appearance and taste. Therefore with using this method, Qzel Ozum and Rasha, could be stored in cold rooms for five months and Sefide-bidane for three months.
