Abstract

Previous studies reported that Salt Creek grape rootstock ‘Ramsey’ promising in grape industry that can face climatic changes which resulting soil problems that limit grape cultivation. Ramsey can tolerate salt and drought conditions without decreasing yield production. It has also high resistance to phylloxera and nematodes. From the other side cuttings of Ramsey face rooting difficulties. The aim of this study was to improve cuttings (intermediate and basal) traits of Ramsey via different cultural media (sand; sand: Peat moss, 3:1 v/v; sand: biochar, 3:0.5 v/v (Char1); sand: biochar, 3:1 v/v (Char2) and IBA concentration (0, 1000 and 2000 ppm). Cuttings growth were followed by measuring shoot length and thickness, leaves number per shoot, leaf area, root length, number of root per cutting and root thickness. In addition, cuttings nutritional status of different elements such N, P, K, Ca and Mg were determined. Results showed that two type cuttings treated with 2000 ppm IBA were better than 1000 IBA treatment. Moreover, two type cuttings grown in Char2 media were superior on that grown in Char1 and both were superior on that grown in sand. Hence it could be concluded that using the intermediate cutting with 2000 ppm IBA in biochar media for Salt Creek grape rootstock ‘Ramsey’ propagation.
