The influence of late-season boron (B) application on the bud B concentration and fruit set was studied in sweet cherry (Prunus avium L.). The experiment was carried out on 5-year-old ‘Summit’ and ‘Hedelfinger’ trees on rootstock Gisela 5 in Fruit Growing centre Gačnik. Trees were sprayed with B (1% Bortrack) or water (control). Differences in B concentration were measured between cultivars, th...

The effects of regulated deficit irrigation (RDI) were studied on 9 year-old apricot-trees (Prunus armeniaca L. cv. ‘Búlida’) grafted on ‘Real Fino’ rootstock. Two irrigation treatments were established. The first, a control treatment, was irrigated to fully satisfy the crop water requirements (100% ETc) and the second, a RDI treatment, was subject to water shortage during the non-critical peri...

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’,...

Two trials were conducted under Mediterranean conditions to monitor several physiological indicators before harvest (leaf chlorophyll concentration, quantum yield of photosystem II electron transport, stem water potential, and stomatal conductance) some agronomic performance parameters at (vigor, fruit growth, size, weight, yield), ‘Vairo’ almond ‘Big Top’ nectarine cultivars grafted onto eight...

In the last years, an important renewal of plant material from different breeding programs is taking place in apricot order to improve resistance biotic stresses, extension harvest season, fruit quality, and productivity. However, graft compatibility many these cultivars with most popular Prunus rootstocks unknown, this essential agronomical trait for their better performance longevity. Hence, ...

Abstract Armillaria and Desarmillaria spp. are causal agents of a devastating root-borne disease peach. Breeding resistant rootstock requires reliable screening tool. An in vitro co-culture screen designed for almond was modified by replacing agar-gelled medium with more aerated phenolic foam combining susceptible rootstocks ( i.e. , common garden experiment) minimizes variation inoculum pressu...

The aim of this study was to trace the Fe uptake pathway in leaves of Prunus rootstock (GF 677; Prunus dulcis × Prunus persica) plants treated with foliar Fe compounds using the Perls blue method, which detects labile Fe pools. Young expanded leaves of Fe-deficient plants grown in nutrient solution were treated with Fe-compounds using a brush. Iron compounds used were the ferrous salt FeSO4, th...
