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 ...

Drought stress is the most important factor limiting successful production of agricultural crops worldwide. The response some almond cultivars grafted on GF677 rootstock was studied to drought at a research greenhouse in Horticultural Science Research Institute Karaj, Iran, 2016-2017 growing season. plant materials included 12 (Prunus dulcis Mill.) genotypes/cultivars, including ‘Sh10’, ‘Saba’,...

Citrus are one of the most relevant fruit crops in Mediterranean basin, which is second-highest citrus-growing region world. However, these mainly grown under semi-arid conditions, characterized by long periods drought and torrential rain. In this work, we have assessed response three promising HLB-tolerant citrus rootstocks (Orange-14, UFR-1, B11R3T27) to application four water stress conditio...

Harmony grape rootstock displays resistance to several Meloidogyne spp. but that resistance is not durable in commercial vineyard settings. A 2-year experiment in a microplot setting revealed host specificities of two virulent populations of Meloidogyne arenaria and an avirulent population of Meloidogyne incognita. In a subsequent split-root experiment, the avirulent nematode population was dem...

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...

An indicator of the condition plants, depending on growing conditions, is state their leaf apparatus, which described by content chlorophyll and nutrients in leaf. The an apple-tree provides synthesis organic substances, productivity fruit trees depends features its vital activity. As a method diagnosing mineral nutrition crops, chemical analysis leaves important, indicators reflect levels plan...

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...
