hazelnuts are usually propagated by suckers or layering. however, other methods of propagation have been tested with variable results. grafting is a method that has a few advantages such as fast multiplication rate, earlier fruiting and reducing sucker removal cost on specific rootstocks. unfortunately, grafting is difficult due to slow formation of callus in hazelnuts. here, we report the hypo...

Rootstock cuttings infected with latent Grapevine Trunk Diseases (GTD’s) pathogens are a major problem for nurseries. These fungal include several species of the genera Phaeoacremonium, Phaeomoniella, Cadophora, Dactylonectria, Ilyonectria, Diaporthe and family Botryosphaeriaceae. Infected rootstock can cause losses up to 60 % during propagation post planting, be reservoir disease in vineyard. ...

UCB-1 (Pistacia atlantica × P. integrima) is a commercial rootstock for pistachio in some pistachio plantations across the world. This rootstock is very new in Iran and recently, it has been used commercially in some plantations due to its high growth. Propagation of this rootstock by tissue culture results in many limitations such as shoot tip necrosis (STN) and a low proliferation rate. There...

ABSTRACT Using nematode-resistant and/or -tolerant rootstock is a strategy that has maintained guava cultivation feasible in the irrigated perimeters of Brazilian semi-arid region. The objective was to evaluate production, gas exchange, and fruit quality ‘Paluma’ with without nematode-tolerant under different irrigation depths production periods. experimental design randomized blocks, mixed 2 ×...

In sweet orange ‘Pêra-Rio’ and acid lime ‘Tahiti’ citrus plants (Citrus spp.) stalked on “Cleopatra” mandarin, a necrosis in the grafting point was observed, causing plant death and dry fruits. Aiming to identify the causes of changes in the rootstock, which lead to grafting incompatibility, an anatomical study comparing plants with and without symptoms, stalked on Rangpur lime, was performed. ...

Most fruit-tree breeding projects are based on selection of seedlings in regard to their performance. The selected seedlings are vegetatively propagated, usually by grafting. It is highly important for the breeder to know whether the performance of the grafted tree will resemble the performance of the original seedling. In this study the performance of avocado and mango seedlings was compared w...

abstract salinity tolerance is one of the major factor influencing crop productivity in arid and semi-arid areas. the salinity tolerance of fruit trees can be enhanced through the use of tolerant rootstocks. this experiment was conducted to investigate the effects of salinity stress and rootstock on the growth, photosynthetic rate and nutrient concentrations of almond (prunus dulcis miller.) cv...

the present study was carried out in order to test the effect of grapevine rootstocks root growth on biomass and leaf nutrition status in extreme soil conditions. own rooted cuttings of rootstocks fercal, teleki kober 5bb, georgikon 28 and four new rootstock hybrids from the breeding program of georgikon faculty, hungary (fb01, jb01, zamor 17 and szf10) were grown 3 months in pots. the 5 l pots...
