this study was undertaken to identify morphological changes in young seedlings of 5 iranian almond species (prunus dulcis, p. eburnea, p. eleagnifolia, p. haussknechti, and p. scoparia) under polyethylene glycol-induced drought stress. drought stress caused a significant reduction in plant growth parameters such as fresh and dry weights of plant organs, leaf number, total leaf area, and leaf re...

tomato ringspot virus (torsv) is a member of the genus nepovirus, family secoviridae, causing substantial economically declining in perennial crops, including stone fruits, worldwide. during the years 2008 and 2009 a total number of 414 symptomatic and asymptomatic leaf samples were randomly collected from different stone fruit trees including peach, apricot, plum and sour cherry from fars and ...

The total area used for fruit cultivation in Tunisia is approximately 470,000 ha, producing mainly citrus, grapevine, stone and pome fruits. Stone fruits are cultivated on some 380,000 ha. Among the stone fruits traditionally grown in Tunisia, almond is the most important and widespread crop (310,000 ha). Peach ranks second with about 22,000 ha, while apricot and plum rank third and fourth, bei...

Over the last 20 years stone fruit rootstock development has begun shifting from seedling to clonal types, many of interspecific origin. Publicly funded breeding programs have produced most of these rootstocks due to the time, cost, and risk associated with their development; however, private industry is emerging as a significant contributor of many of the newer rootstocks. Particularly notewor...

The high-throughput sequencing of pear "Dangshan Su" × "Yali" (whose fruits lignin and stone cell content are high and quality is poor) and pear "Dangshan Su" × "Wonhwang" (whose fruits with low content of lignin and stone cell and the quality are better ) found that the expressions of these two miRNAs (pyr-1809 and pyr-novel-miR-144-3p) were significantly different; their corresponding target ...

Postharvest quality in stone fruits is ultimately defined in terms of consumer satisfaction, and includes appearance, texture and flavor, and nutritional value and safety. These result from all decisions and practices beginning with site and cultivar selection, and extending through cultural practices and all stages of postharvest handling. The development of high quality fruit is influenced by...

Prunus necrotic ringspot virus (PNRSV) causes yield loss in most cultivated stone fruits, including sweet cherry. Using a small RNA deep-sequencing approach combined with end-genome sequence cloning, we identified the complete genomes of all three PNRSV strands from PNRSV-infected sweet cherry trees and compared them with those of two previously reported isolates.

this study investigated the export status of stone fruits in iran during 1997 to 2010.export trends and revealed comparative advantage of indices, namely, revealedcomparative advantage (rca), revealed symmetric comparative advantage (rsca),and relative export advantage (rxa) as well as trade mapping (tm) were investigatedfor cherries, plums, peaches, and apricots. target markets for these produ...
