The development of water stress resistant lines of commercial tomato by breeding or genetic engineering is possible, but will take considerable time before commercial varieties are available for production. However, grafting commercial tomato lines on drought resistant rootstock may produce drought tolerant commercial tomato lines much more rapidly. Due to changing climates and the need for com...

The present study examined free-radical scavenging enzyme activity and the levels of lipid peroxide, ascorbic acid, nitric oxide and glutathione in 1616C rootstock and the Razaki cultivar of Vitis vinifera L. under treatment with different concentrations of salt. At day 7, in leaves of both 1616C rootstock and cv. Razaki treated with 12 mM NaCl there were significant increases in glutathione pe...

The performance of three different rootstock (Adara (Prunus cerasifera L.), SL 64 (Prunus mahaleb), and Colt (Prunus avium x Prunus pseudocerasus)) as nutrient suppliers has been studied for sweet cherry cultivars (Prunus avium L.). The results obtained suggested that, depending on the rootstock, the trees are submitted to different degrees of stress. According to the data obtained, it could be...

The cultivar and rootstock effect on iron chlorosis were studied. The results revealed significant differences among peach cultivars and rootstocks in mineral content. Seasonal changes were also found in the macroand micronutrient content of leaves of peach cultivars and rootstocks. The rootstock St. Julien 655/2 was found to be efficient in K, P, Zn, Fe, Cu absorption and better than seedling ...

Plant grafting is an important technique for horticultural and silvicultural production. However, many rootstock plants suffer from undesirable lateral bud outgrowth, low grafting success rates or poor rooting. Here, we used a root-predominant gene promoter (SbUGT) to drive the expression of a tryptophan-2-monooxygenase gene (iaaM) from Agrobacterium tumefaciens to increase auxin levels in toba...

Grapevine (Vitis) rootstock varieties or cultivars are used to confer resistance and tolerance to insect and disease pests, unfavorable soil conditions, and other environmental conditions to cultivars that are susceptible to these conditions but otherwise have desired properties. The need to genotype and thoroughly identify grapevine rootstock varieties in the grape industry has become increasi...

Use of dwarfing rootstocks has dramatically increased the profitability of fruit production by reducing production costs, reduced chemical use and higher density plantings. Despite the importance of rootstock-induced dwarfing, the cause of this phenomenon is not known. Using two commercially available graft combinations consisting of a sweet cherry scion, 'Bing', on a dwarfing rootstock (Gi5) o...

Reports that “own rooted” Chandler walnuts (Chandler clone) out preformed grafted trees stimulated the creation of this replicated trial to investigate the performance of Chandler clone trees, Chandler clone grafted to Chandler clone rootstock, Chandler clone grafted to three selections of paradox rootstock and Chandler clone grafted to a vigorous English rootstock. Rootstock trees were planted...
