in this study the effects of plant growth regulators including; ga3 (0 and 50 mg/l) and ethephon (0 and 500 mg/l) were studied on the quality properties of two grape cultivars (perlette and yaghuti). at the harvest time, some physicochemical characteristics such as fruit cluster weight, fruit diameter, length, volume and l/d ratio, flesh firmness, fresh weight, ta, ph, tss and fruit color were ...

a study of two years was carried out on apples, red delicious cv. in comeh of semirom region. the objective of this research was to assess the effect of pre-harvest calcium phosphate (seniphos) spraying and summer pruning on the skin color and quality characteristics of the fruit. study was carried out using a complete randomized block design with 3 replications. trees were subjected to pre-har...

increasing product marketability and introduction of new cultivars for fresh consumption of apple is the world's most important breeding objectives. in this study, the qualitative and quantitative characteristics of the genotypes from cross between red spur and golab-e-kohanz apple cultivars were evaluated. a total of 19 traits including fruit attributes (firmness, fruit weight,...) and th...

The fruit of Schisandra chinensis Turcz. (Baill.), namely "Wuweizi" in China, is a well-known herbal medicine and health food. At present, research focused on the extraction of effective chemical component and function identification. Little known about the secondary metabolism gene pathway of chemical composition. Its fruit color usually red, however, the white fruit color variation has been f...

food quality, marketability, soluble solids, size and color of nectarine fruit is affected by the intensity and amount of direct sunlight. usually the outer areas of fruit trees get enough light and take the appropriate color. however, in the middle and lower part of trees, due to low light intensity, fruits have no good color and taste and their marketability were not desirable. to improve the...

sensitivity of tomato fruit to low temperature and chilling injury limits the storage, handling and marketability of the fruit. as a recommended postharvest treatment, effects of hot water treatment (hwt) on reducing chilling injury and quality traits, variation of tomato fruits during storage life were investigated. tomato fruits were harvested at mature green stage. they were treated by hot w...

Marker-assisted selection (MAS) in stone fruit (Prunus species) breeding is currently difficult to achieve due to the polygenic nature of the most relevant agronomic traits linked to fruit quality. Genotyping by sequencing (GBS), however, provides a large quantity of useful data suitable for fine mapping using Single Nucleotide Polymorphisms (SNPs) from a reference genome. In this study, GBS wa...

the effects of different stages of maturity (mature green, until 20 to 40% of change in color), two treatments of cool water (5 ?c for 5' and 10 ?c for 15min.), two treatments of hot water (50 ?c for 15 min. and 55 ?c for 5 min.) ), two temperatures (10 and 14 °c) of storage vs. six time periods (0, 5, 10, 15, 20 and 25 days) on shelf life and storage time of ‘langra’ mango fruit were stud...

Anthocyanin in strawberries has a positive effect on fruit coloration. In this study, the role of exogenous hematin on anthocyanin biosynthesis was investigated. Our result showed that the white stage of strawberries treated with exogenous hematin had higher anthocyanin content, compared to the control group. Among all treatments, 5 μM of hematin was the optimal condition to promote color devel...
