abstract one way of the increasing saline tolerance in citrus plants is grafting of sensitive commercial cultivars on to tolerant rootstocks. sweet lime (citrus limetta) is one of the most sensitive species to salinity of soil and water, and under such conditions, drastic reduction of both vegetative and yield occured. this reaserch was conducted in completely randomaized design with factorial ...

a principal obstacle facing intensive pear orchard establishment in iran is the absence of appropriate dwarfing or semi-dwarfing rootstocks, compatible with commercial cultivars, as well as showing adaptability with alkaline soils. this research aimed at an evaluation of the hawthorn seedlings (crataegus sp.) as a potential dwarfing rootstock for pear and a comparison of its dwarfing effects wi...

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 ...

Citrus production in Florida declined steadily because of Huanglongbing (i.e., HLB, citrus greening) caused by the bacteria Candidatus Liberibacter asiaticus. The objectives study were to determine whether leaf tissue nutrient concentration, tree growth, fruit yield, and juice content improved with split applications essential nutrients on selected rootstocks sandy soils. treatments arranged a ...

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...

Fluctuations of winter and summer and day and night temperatures strongly influence shoot and root growth, as well as the whole plant tolerance to extreme soil temperatures. We compared the response of a commercial pepper (Capsicum annuum L.) hybrid (Romance, Rijk Zwaan) to a range of soil temperatures when grafted to a new rootstock hybrid (S101, Syngenta), self-grafted, or ungrafted. The new ...

This study was carried out at Sedyghazi private orchard located in Abu Ghaleb road 164 kilometer from Cairo to Alex desert road, Giza, governorate Egypt during two seasons (2019 and 2020) on thirteen - year old Le-Conte pear trees budded Pyrus communis rootstock, planted 3.5 × 4 meters apart grown sandy soil under drip irrigation system (EC= 3.40 dS m−1). . The experiment arranged a spilt plot ...

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...
