Plums (Prunus spp) are among the most important stone fruit crops in the world. European (Prunus domestica) and Japanese (Prunus salicina) plums are characterized by different levels of ploidy. Because genetic variability is the prerequisite for any plant-breeding program, we aimed to establish the taxonomic status of Tunisian plums and study their genetic variability. The nuclear DNA content o...

The genus Phaeoacremonium is associated with opportunistic human infections, as well as stunted growth and die-back of various woody hosts, especially grapevines. In this study, Phaeoacremonium species were isolated from necrotic woody tissue of Prunus spp. (plum, peach, nectarine and apricot) from different stone fruit growing areas in South Africa. Morphological and cultural characteristics a...

Xanthomonas arboricola is a plant-associated bacterial species that causes diseases on several plant hosts. One of the most virulent pathovars within this species is X. arboricola pv. pruni (Xap), the causal agent of bacterial spot disease of stone fruit trees and almond. Recently, a non-virulent Xap-look-a-like strain isolated from Prunus was characterized and its genome compared to pathogenic...

Hybridization has played a central role in the evolutionary history of domesticated plants. Notably, several breeding programs relying on gene introgression from the wild compartment have been performed in fruit tree species within the genus Prunus but few studies investigated spontaneous gene flow among wild and domesticated Prunus species. Consequently, a comprehensive understanding of geneti...

the current experiment was carried out to evaluate qualitative and quantitativeof three melons (cucumis melo gp. ameri) accssions named zardjalal, ananasi and khanoti. the experiment was conducted in a randomized complete block design (rcbd) with 16 treatments and three replications at research field of jahad-e-daneshgahi, campus of agriculture and natural resources, university of tehran. five ...

The majority of the citriculture in Brazil is located in the state of São Paulo, with a total production area of 700,000 ha. Trees are grafted mostly on ‘Rangpur’ lime (RL; Citrus limonia Osbeck) rootstock. Despite its good horticultural performance, use of other rootstocks has increased with the search for disease-tolerant varieties to improve grove productivity and longevity. Furthermore, the...

Earliness is also very important in addition to yield and fruit quality for more profitable production sweet cherry cultivation. Therefore, some preparats are applied get flowering even earlier Kemalpaşa District of Izmir province, where fruits from Turkey harvested the earliest. In this study, it was aimed determine effects different treatments pre-flowering period on fruits. The study carried...

Citrus are one of the most relevant fruit crops in Mediterranean basin, which is second-highest citrus-growing region world. However, these mainly grown under semi-arid conditions, characterized by long periods drought and torrential rain. In this work, we have assessed response three promising HLB-tolerant citrus rootstocks (Orange-14, UFR-1, B11R3T27) to application four water stress conditio...

The interim results of many years work on the creation pear varieties - genetic dwarfs and dwarf rootstocks an intensive type with a high adaptive potential suitable for setting gardens in conditions Central region Russia are presented. At first stage obtained from crossing highly winter-resistant disease-resistant donors various origins monogenic determined dwarfism, group resistance to diseas...
