Abstract Background Previous literatures revealed that gamma rays have an increasing effect on salt tolerance in different plants. In vitro experiment was conducted to study the of (20 Gray) four potato cultivars (Lady Rosetta, Diamante, Gold, and Santana). Results Gamma-treated Santana plantlets were more tolerant salinity as compared other cultivars. It showed a significant increment fresh we...

Drought stress is considered as a main restriction to have the best potential crops performance in arid and semi-arid regions world. Hence, some mechanistic strategies are required manage drought detrimental influences. Silicon an essential mineral nutrient, plays important role physiology, metabolism, function of exposed stress. This study was carried out evaluate influences various irrigation...

The plant elicitors use as an agricultural input is limited and few studies show their influence on physiological responses. However, its can induce broad-spectrum long-lasting resistance in plants by inducing defense systems, primary secondary metabolism. the aim of this study was to evaluate gas exchange (gs, A, E, Ci, WUE, iWUE iCE) enzymatic antioxidant system (POD, PPO PAL) Z. mays under a...

Abstract Background Persimmon fruits are cherished for their unique flavor and high nutrient content. In the present study, effects of Aloe vera -based edible coatings (EC) added with 1% ascorbic acid, citric acid 5% calcium chloride in modified atmosphere packaging (MAP) impact on shelf-life quality fresh-cut persimmon fruit, were investigated. The experimental design consisted four treatments...

As it was previously reported, black spot development in the skin of Hass avocado has been related to a decreased antioxidant defense system. The aim this study investigate effect different postharvest storage conditions on controlling targeting their system (non-enzymatic and enzymatic) skin. Four treatments (T1: regular air (RA) at 5 °C for 40 d; T2: controlled atmosphere (CA) 4 kPa O2 6 CO2 ...

Tomato Lycopersicon esculentum Mill. is one of the most cultivated and widely consumed vegetables in world. However, it very susceptible to infection initiated by Fusariumoxysporum fruit rot, which shortens post-harvest life thus reduces market value. This disease can be regulated appropriately application synthetic fungicides. chemical fungicides constitute a serious health risk, have harmful ...

In this study, some quality changes in the optimally thermosonicated (59°C-455 J g-1) cloudy strawberry nectar during storage were evaluated and modelled. The of pH (3.40-3.78), residual polyphenol oxidase-(PPO) activity (24%-11%), total phenolic-(TP) content (688.7-543.2 mg L-1), monomeric anthocyanin-(TMA) (142.5-84.4 anthocyanin, colorless phenolic compounds analyzed three months at 4°C. sig...

Many forages experience significant proteolytic losses when preserved by ensiling. Such losses in alfalfa (Medicago sativa L.) are especially high, with degradation of 44 to 87% of the forage protein to nonprotein N (NPN). In contrast, red clover (Trifolium pratense L.) has up to 90% less proteolysis during ensiling. Here we demonstrate that the combination of polyphenol oxidase (PPO) and o-dip...

Aril browning threatens production, consumption, and exports of pomegranates, because affected fruit cannot be externally distinguished from healthy fruit. This study compared the mineral, biochemical composition, and related enzyme activities in affected brown arils with healthy ones in ‘Malase Saveh’ pomegranates. The results indicated that concentrations of Cu in the aril and K, Mg, and Mn i...

Background & Aim: Glycyrrhiza L. (Fabaceae) consists of perennial herbs grow in sandy soils with hard lightness. Three species of the genus grow in Iran, among them G. glabra L. has the widest distribution. It is well known in English as Licorice and the root extract includes flavonoids and glycyrrhizin are used widely in medicine, food industry, tobacco products and other ind...
