Iron deficiency induces several responses to iron shortage in plants. Metabolic changes occur to sustain the increased iron uptake capacity of Fe-deficient plants. We evaluated the metabolic changes of three Prunus rootstocks submitted to iron chlorosis and their different responses for tolerance using measurements of metabolites and enzymatic activities. The more tolerant rootstocks Adesoto (P...

The continuous release of new nectarine [Prunus persica (L.) Batsch] cultivars by breeders from around the world, together with consistent improvements in orchard management strategies growers, commercial interest production fruit fresh consumption, and introduction Spanish scion breeding programs have positioned Spain as preeminent worldwide exporter currently largest European producer [Minist...

Abstract Objectives Peach (Prunus persica L.) is an ancient fruit tree that originated from China. It the climacteric belonging to genus Prunus in family Rosaceae. Ethylene, which produced during ripening, accelerates softening, and therefore peaches cannot be stored for a long time. Materials Methods To study mechanism of late transcriptome analysis late-ripening mutant ‘Jinghong’ peach was pe...

The response of the peach scion cultivars, Jerseyqueen, Redhaven, Compact Redhaven, and Rio Oso Gem and rootstocks 'Lovely and 'Nemaguard' to inoculation with Meloidogyne incognita was compared in vitro and in microplots. One or more parameters monitored in vitro correlated with at least one parameter monitored in microplots, 4 years after tree planting (1989). A range of responses was observed...

We studied relationships between diurnal patterns of stem water potential (PsiSTEM) and stem extension growth of the same scion cultivar growing on three rootstocks with differing size-controlling potentials. The peach trees (Prunus persica (L.) Batsch) used in this field experiment consisted of an early-maturing freestone cultivar, 'Flavorcrest,' grafted onto three different rootstocks: Nemagu...

Peaches (Prunus persica cv. Yanhong) were fumigated with carbon monoxide (CO) at 0, 0.5, 5, 10, and 20 μmol/L for 2 hours. The result showed that low concentration CO (0.5-10 μmol/L) might delay the decrease of firmness and titrable acid content, restrain the increase of decay incidence, and postpone the variation of soluble solids content, but treating peaches with high concentration CO (20 μm...
