Abstract
The present study was carried out during two successive seasons of 2012 and 2013 in a private vineyard located at Sadat city, Menofia Governorate, Egypt. to investigate the influence of three grapevine rootstocks; namely, Harmony, Freedom and Salt creek at two different grafting dates using Cleft grafting method on the percentage of survival and growth parameters of Flame seedless cv. at two grafting dates.(January and February months). The survival percentage and (F.C.C.) varied significantly according to rootstock type, grafting dates and the interaction between them. Freedom rootstock recorded the highest survival percentage and (F.C.C.) in 2012 and 2013 seasons, respectively, while Harmony rootstock exhibited the lowest figures in both seasons, regardless of grafting date. Meanwhile, rootstocks grafted in mid February recorded significantly higher survival percentage in 2012 and 2013 seasons than those grafted on mid January regardless of rootstock type. The same result was detected for F.C.C. value in 2012 season only. On the other hand, Feb. grafting exhibited greater shoot length and leaf area than Jan. grafting regardless of rootstock type. The interaction between rootstock type and grafting date showed that Flame seedless cv. grafted on Freedom rootstock on mid February gained the maximum values of scion shoot length (93.84 and 100.15 cm) and leaf area (130.35 and 143.69 cm2) in 2012 and 2013 seasons, respectively. Contrastly, the same scion when grafted on Harmony rootstock on mid January recorded the minimum value of shoot length (59.12 and 56.16 cm) and leaf area (51.27 and 64.10 cm2) in 2012 and 2013 seasons, respectively. Freedom rootstock recorded the maximum figures of fresh and dryweight of the aerial portion (leaves and shoots) and root systemin the two seasons followed by Salt creek rootstock without significant difference between them. While, Harmony rootstock showed the minimum values in the two studied seasons. Grafting in Feb. 15th was better than in Jan. 15 th especially in 2012 season regardless of rootstock type.
