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...

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...

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...

Research to date indicates that post-transcriptional gene silencing (PTGS) is an effective strategy for the development of stable high-level resistance to Plum pox virus in plum. Field tests in Poland, Romania, and Spain show that after 5–6 years of natural aphid vectored inoculation, trees of the PTGS clone C5 remain virus-free. The effectiveness of transgene-based PTGS for imparting potyvirus...
