Performance of some Table Grape Cultivars Grafting on Different Rootstocks in El-Nubaria Region

Abstract

This study had made in El-Nubaria region at the desert street Alex, Cairo 75 km during 2012 and 2013 seasons. Three different scions from Europe grape vine on three different rootstocks are used in this study, their age is six years old in private orchard, sandy clay loom soil on spaced at 2×3 m and irrigated by drip. The results showed that, Flame seedless scion grafted on different rootstocks gave the earliest time for bud burst time, flowing time, time of cluster flower setting, berry coloring time and time of berry ripening comparing with Superior and Thompson scions and ungrafted cultivars. Moreover, data showed that Superior seedless and Thompson seedless cultivars scions on Freedom, Polcin1103 and salt Greek rootstocks gave the better number for internodes/cane per vine comparing to Flame seedless cultivars grafted on Freedom, Polcin1103 and salt Greek rootstocks in both seasons. Flame seedless and Superior seedless cultivars grafted on Freedom, Polcin 1103 and salt Greek rootstocks gave the better berry adherence strength per vine, yield and yield components in contract to Thompson seedless cultivars grafted on Freedom, Polcin 1103 and salt Greek rootstocks in two seasons. Leaf mineral contents in scions understudy did not clearly affected with type of rootstocks comparing with ungrafted scions, Polcin1103 rootstock increased all leaf mineral contents understudy followed by Freedom, salt Greek stock and finally ungrafted scion. Also, leaf of Superior seedless contained the highest values of elements followed by Thompson seedless and Flame seedless regardless the type of rootstocks.

Modifications of ‘Gold Finger’ Grape Berry Quality as Affected by the Different Rootstocks

“…SO4, 101-14M, and especially 3309C enhanced cluster weights and yields, which were estimated in light of average cluster weights, compared to the control vines (Table ). Similarly, regardless of the type of scion cultivars, 1103P, ‘Freedom’, ‘Salt Greek’, and some other rootstocks led to higher yields than own-rooted vines. − Additionally, grafting significantly increased grape and eggplant yields regardless of the different changes in other fruit traits in two successive years. , Therefore, it might be a common phenomenon for most resistant rootstocks to increase fruit yield.…”

“…Content of sugars and acids determines, to a great extent, the organoleptic quality and flavor of table grapes. Rootstocks often modified berry sugar and acid content, but great variations have also been observed among different combinations of rootstocks and scion cultivars . The ratio of TSS to TA is commonly used to evaluate fruit taste.…”

“…Rootstocks often modified berry sugar and acid content, but great variations have also been observed among different combinations of rootstocks and scion cultivars. 24 The ratio of TSS to TA is commonly used to evaluate fruit taste. 101-14M maintained the levels of TSS, TA, and TSS/TA and hence maintained berry flavor.…”

Yield components of the new seedless table grape ‘BRS Ísis’ as affected by the rootstock under semi-arid tropical conditions

“…Greater vigor was observed in the second semester 2017 in grapevines of 10 months of age, and this was the only production cycle in which there was an effect of the rootstock on vigor, obtaining more vigorous grapevines grafted onto the rootstock Paulsen 1103 compared to 'IAC 572', 'IAC 313', and 'Freedom'. Grapevines grafted onto 'Paulsen 1103' were also more vigorous, according to Koundouras et al (2008) and Aly et al (2015), but these results are not in agreement with those obtained in 'Crimson Seedless' and 'Superior Seedless', where greater vigor was found in grapevines grafted onto 'IAC 572' (Feldberg et al, 2007). Differences were not observed among rootstocks in the mean values of the four production cycles evaluated in this study (Table 2), which may be attributed to the fact that under optimal conditions of supply of water and nutrients, and considering that BRS Ísis grapevines have naturally high vigor, the rootstocks responded in a similar manner.…”
