the aim of the study was to evaluate changes of sorbitol, glucose, fructose, sucrose, and total sugars of plum fruits in different years under different climatic conditions i.e. air temperature and precipitation. the cultivars investigated in the research were: topstar, toptaste, jojo, haganta, tophit, and top 2000. the fruits were harvested at optimal stage of maturity in the experimental orch...

Plums are climacteric fruits: their ripening is associated with a burst of ethylene production and respiration rate. Stone fruits, including plum, have a distinct pattern of growth and development, described as a double sigmoid pattern. In order to understand the developmental control of ethylene perception in plum, four ethylene perception and signal transduction components (EPSTCs) were chara...

Ethylene has long been considered the key regulator of ripening in climacteric fruit. Recent evidence showed that auxin also plays an important role during fruit ripening, but the nature of the interaction between the two hormones has remained unclear. To understand the differences in ethylene- and auxin-related behaviours that might reveal how the two hormones interact, we compared two plum (P...

The phenolic composition of skin and flesh from Malus domestica apples (Anna cultivar) and Prunus domestica plums (satsuma cultivar) commercial cultivars in Costa Rica, was studied using Ultra Performance Liquid Chromatography coupled with High Resolution Mass Spectrometry (UPLC-DAD-ESI-MS) on enriched-phenolic extracts, with particular emphasis in proanthocyanidin and flavonoids characterizati...

Among popular crops, plum (Prunus domestica L.) has received special attention due to its health-promoting properties. The seasonality of this fruit makes it impossible to consume it throughout the year, so new products in a powder form may offer an alternative to fresh consumption and may be used as high-quality natural food ingredients. A 100% plum (cultivar "Valor") juice was mixed with thre...

One factor that contributes to a successful fruit tree grafting is the establishment of symplasmic contacts in the graft interface to facilitate the transfer of compounds between scion and stock. Using novel experimental and theoretical approaches we investigated whether the localized incompatibility, experienced in some Prunus grafts, could be related to insufficient plasmodesmal coupling at a...

Plum bark necrosis-stem pitting (PBNSP) disease was first observed in 1986 affecting plum (Prunus salicina Lindl.) cv. Black Beaut trees in two orchards in Dinuba, CA (8). All of the Black Beaut plum trees had been whip-grafted with a single cultivar Wickson plum scion per tree to serve as a pollenizer, and all Wickson grafts failed. A year later, the same trees were grafted a second time with ...

the aims of this study were to investigate the energy flow and its modeling in shablon cultivar of plum production in golestan province of iran. data were collected through questionnaires and also interviews with producers. cobb-douglass model and sensitivity analysis were used to determine the effects of energy inputs on plum yield. the results revealed that the total energy inputs and energy ...

Anthocyanins are important pigments and are responsible for red coloration in plums. However, little is known about the molecular mechanisms underlying anthocyanin accumulation in plum fruits. In this study, the RNA-seq technique was used to analyze the transcriptomic changes during fruit ripening in the red-fleshed plum (Prunus salicina Lindl.) cultivar 'Furongli'. Over 161 million high-qualit...

ABSTRACT The dynamics of virus interference between two isolates of Plum pox virus (PPV) belonging to the main PPV types, D and M, were analyzed in Japanese plum (Prunus salicina) by challenge inoculations. To assess the consequences of a PPV-M infection on plum already infected with PPV-D, and vice versa (predominance of one of the strains, recombination, synergism, symptoms aggravation, and s...
