A reasonable main branch opening angle can improve the canopy light environment of a tree, change direction nutrient transport, and promote formation flower buds. In this experiment, 3-year-old ‘Lu Hong 618’ was used as test material to study effects different angles (three treatments: 45°, 65°, 85°) on distribution, characteristics, fruit quality, bud quality ‘Y’-shaped peach trees. The findin...

Fruit firmness and crispness are important traits of cucumber because they directly affect its commercial value. We performed quantitative trait locus (QTL) analysis these fruit texture with the double-digest restriction-site-associated DNA sequencing (ddRAD-Seq) technique detected 31 QTLs for firmness: 11 placenta firmness, 12 skin 8 flesh firmness; 25 crispness-related scores: 10 index, appar...

Apple fruit are well known for their storage life, although a wide range of flesh softening occurs among cultivars. Loss of firmness is genetically coordinated by the action of several cell wall enzymes, including polygalacturonase (PG) which depolymerizes cell wall pectin. By the analysis of 'Fuji' (Fj) and 'Mondial Gala' (MG), two apple cultivars characterized by a distinctive ripening behavi...

To investigate the role of ethylene in peach fruit softening during ripening, stony hard peach fruit, in which ethylene production is suppressed during ripening, were treated with various concentrations of ethylene. There was no noticeable decrease in flesh firmness without ethylene treatment, while applied ethylene, in the range 0.1-100 microl l(-1), resulted in fruit softening. Furthermore, t...

Fresh-cut fruit slices prepared from partially ripened Bartlett pears had longer shelf life than those from Bosc, Anjou, and Red Anjou pears. Pear fruit ripeness, based on flesh firmness of 44 to 58 N, is optimal for fresh-cut pear slice processing. Pear slices derived from smaller size fruit (122 to 135 g) have greater cut surface discoloration and deteriorate more rapidly than slices derived ...

Apple is one of the most important fruits in temperate zones with a long post-harvest life during cold storage. A factorial experiment, in a randomized completely block design was used to investigate the preharvest application of Iron (0, 500 and 1000 mg Fe-EDDHA per tree) and nitrogen (0, 48 and 96 g ammonium nitrate per tree( on some postharvest qualitative characteristics in "Red spur" and "...

The commercial application potential of hot water treatments against 1-Methylcyclopropane (1-MCP) for maintaining quality fruit in quince (Cydonia oblonga Mill. cv. ‘Eşme’) during long-term regular air storage was investigated. fruits were treated with either at 50 ± 1 °C 3 and 5 min or two different 1-MCP (SmartFreshSM) concentrations (300 ppb 1000 ppb) 12 20 h. Then, all stored 0 temperature,...
