The effects of three Arbuscular Mycorrhizal Fungi (AMF) species (Glomus versiforme, Claroideoglomus etunicatum and Rhizophagus intraradices) were studied on the growth parameters and nutrient uptake of three apple rootstocks (M.9, M.7 and MM.106). The soil medium contained a high level of calcium carbonate (38.65%). The results showed that AMF inoculation could increase almost all growth parame...

Iron is an essential micronutrient for plants, and plants have evolved adaptive mechanisms to improve iron acquisition from soils. Grafting on iron deficiency-tolerant rootstock is an effective strategy to prevent iron deficiency-chlorosis in fruit-tree crops. To determine the mechanisms underlying iron uptake in iron deficiency, two iron deficiency-tolerant citrus rootstocks, Zhique (ZQ) and X...

This study was carried out to evaluation of the effects on pruning weight (kg plant-1), cumulative per plant and hectare ha-1) 3 quince rootstocks [Quince BA29 (BA29), Quince A (QA), C (MC)] pear clonal (Fox11, OHxF333, Farold 40) seedling grafted with 4 standard cultivars (‘Abate Fetel’, ‘Deveci’, ‘Santa Maria’, ‘Williams’) between 2019-2021 years. Rootstocks, cultivars, research years their i...

In order to study plant responses drought stress, it is important have markers for such responses. This issue has been a challenge decades and numerous traits used this purpose. the current study, influence of stress on proline biosynthesis, leaf water potential, also gene expression levels 10 genes probably involved in response regulation pathways were investigated. Also, all experiments perfo...

This study aimed to evaluate the effect of rootstocks on fruit sugars, organic acids, and carotenoids. The contents of sugars and organic acids in fruits were determined by HPLC. Total acidity (TA), total soluble solids (TSS), and pH value of the juice were also evaluated. Total carotenoids and chlorophylls contents were measured using a spectrophotometer. The content of ethylene in fruits was ...

Ink disease caused by the root-rot pathogen P. cinnamomi (Pc) threatens European sweet chestnut (Castanea sativa Mill.) orchards, and growers increasingly graft susceptible C. traditional varieties on Pc-resistant hybrid commercial rootstocks. The influence of scion, rootstock, grafting per se vegetative budburst, growth, susceptibility to Pc defence-related hormone profile Castanea spp. are un...

Two pathogenic isolates of the genus Dactylonectria associated with black foot disease grape rootstocks (2-3 years old) were identified in Duhok province, Iraq. The incidence recorded 67% on plants that lead to weaken or plant failure when severity exceeded 51%. This is characterized by dark brown necrotic lesions at bottom rootstocks, sparse foliage and growth reduction. molecular identificati...
