iran, with a yearly production of 147,000 tons of plums, is one of the most important plum producers in theworld. this study was conducted to compare the phenological and pomological characteristics of 18 plum cultivars. an experiment was conducted using a randomized complete block design with three replications at the khorasan razavi agricultural and natural resource and agricultural research ...

In this paper the nature of root-to-shoot signals in plants growing in drying soil is considered in the context of their commercial exploitation in tomato (Lycopersicon esculentum L.) and other crops. Recent findings are presented on the effects of partial root drying (PRD) in the production of a glasshouse tomato crop. These findings show how an understanding of both root-to-shoot signalling m...

Storage at 3 and 18 °C of 'Arbequina' olives (Olea europaea L.) cultivated in hedgerows and harvested manually or mechanically (wine grape harvester) was tested. Fruit characteristics and oil quality were monitored. Mechanical harvesting caused internal fruit damage that induced its rapid softening and decay, but also facilitated obtaining higher amounts of oil, which suffered a rapid deteriora...

The amount of indole-3-acetic acid (IAA) was measured in peach fruits by gas chromatography-mass spectrometry-selective ion monitoring using an isotope dilution assay with [(13)C(6)]IAA as an internal standard throughout the growing season. Ethylene evolution of the fruit was also measured. IAA levels were 25 nanograms per gram fresh weight, 18 days after anthesis. Both IAA levels and rates of ...

1-Methylcyclopropene (1-MCP), an inhibitor of ethylene perception, has been commercialized as SmartFresh technology for postharvest use on fruits and vegetables around the world. 1-MCP is used widely on apple fruit in North America; its successful commercial uptake has occurred because the technology helps to maintain quality of the fruit, not only during storage, but also through the entire ma...

Seasonal changes in photosynthesis of apple trees (Malus domestica Borkh.) were monitored to examine the effect of source-sink interactions on photosynthesis and photorespiration. Elevated photosynthetic rates were observed during two periods of the growing season and correlated with the fruiting process. The first period of increased photosynthetic rates was during the bloom period, when spur ...

Sustainable and environmentally-conscious fruit growing is a main concern in European agriculture. Using modern breeding technologies, several disease-resistant apple varieties have been developed in recent years. These varieties can be grown with low pesticide use, which means not only sustainable fruit growing, but lower production costs. Before these varieties are used in orchards, it is ess...

this study was conducted under ahvaz, iran environmental condition during 2012 and 2013 growing seasons in order to investigate the influence of foliar application of potassium on some physiological and biochemical characteristics of three olive cultivars including ‘mission’, ‘koroneiki’ and ‘dezfuli’. potassium sulfate in different concentrations of 0, 1, and 2 g l-1 was sprayed twice on selec...

to study the effects of planting date and planting density on quantitative traits of medicinal plant, schneider squash (cucurbita pepo l.), an experiment was conducted at research field of ferdowsi university of mashhad, in year 2012. a split plot arrangement based on randomized complete block design with three replications was used. treatments consisted of three planting date levels (1 may, 11...
