Forest harvesting of increasing intensities is expected to have intensifying impacts on the genetic diversity and population structure of postharvest naturally regenerated stands by affecting the magnitude of evolutionary processes, such as genetic drift, gene flow, mating system, and selection. We have tested this hypothesis for the first time by employing widely distributed boreal white spruc...

application of ethephon is an effective way in increase of grape fruits quality. in this study the effect of preharvest application of ethephon solution at four levels (0, 150, 250 and 300 mg/l)and application time at two levels (10-20% and 50-70% of berry coloring), were evaluated on quality indices of ghizil uzum grape cultivar at harvest time. evaluated indices were soluble solids content, t...

Preharvest sprouting (PHS) is a key global issue in production and end-use quality of cereals, particularly regions where the rainfall season overlaps harvest. To investigate transcriptomic changes genes affected by PHS-induction ABA-treatment, RNA-seq analysis was performed two wheat cultivars that differ PHS tolerance. A total 123 unigenes related to hormone metabolism signaling for abscisic ...

Cold storage is a commonly adopted technology to maintain quality and extend shelf life; however, depending on the cultivar, ethylene production can be enhanced by short-term cold treatments. In this study, index of absorbance difference (I AD ) values, which reflect skin chlorophyll concentrations cold-influenced ripening patterns, ‘Gala’ apples were investigated. Fruit that untreated or treat...

There are various postharvest treatments currently available in the market. Among these, heat-based very effective. Several hot water treatment (HWT) protocols at temperature regimes and time durations have been developed for different mango cultivars varieties. However, many concerns raised regarding quality of fruits subjected to HWT, particularly on physical biochemical properties. The purpo...

A comparison of the invasion of flowers, aerial pegs, and kernels by wild-type and mutant strains of Aspergillusflavas or A. parasiticus along with aflatoxin analyses of kernels from different drought treatments have supported the hypothesis that preharvest contamination with aflatoxin originates mainly from the soil. Evidence in support of soil invasion as opposed to aerial invasion was the fo...

Calcium preharvest application influences fruit quality. The impact of foliar sprays using several commercial fertilizers with Ca content on the quality and nutritional status kiwi cv. ‘Hayward’ was investigated for a 2-year period. Fruit flesh firmness increased under all compared to control. Total soluble solids acidity were not altered significantly by any studied products. Treatment differe...
