Prunus avium cv. 'Fuchen' is a cultivated species with a high-profile economic benefit. Four media were used as a basal media equipped with four exogenous hormones to establish an intact regeneration system. Sodium thiosulfate (Na2S2O3) and active carbon (AC) improved the browning phenomenon. The results indicated that 1.0 g/L of AC and 30 g/L of Na2S2O3 were the best combination to inhibit the browning on the optimal basal medium - olive medium (OM) (followed by woody plant medium). The OM containing 1.5 mg/L of zeatin, 2.0 mg/L of α-naphtalenaecetic acid (NAA) and 0.5 mg/L of kinetin was beneficial for the germination and growth of the axillary...

o investigate the role of selenomethionine (SeMet) in regulating the drought tolerance of strawberry plants, we explored the effects of SeMet on the antioxidative enzymes, water physiology and fruit quality of the strawberry plants under drought stress (DS). In this study, we used the strawberry variety 'Sweet Charlie' as the material and investigated the effects of SeMet on the drought tolerance of the strawberry plants through foliar spraying and pot experiments. The results showed that the DS obviously enhanced the activities of the antioxidant enzymes (ascorbate peroxidase, superoxide dismutase, peroxidase and catalase) and increased the malondialdehyde...

In recent decades, adverse effects of unexpected contaminants on the quality of crops have threatened both the food security and human health. Vegetable production in heavy metal contaminated soils is a serious concern regarding the quality of food. Glutamic acid has been extensively studied as a stress-responsive antioxidant molecule and its function is involved in triggering plant growth during abiotic stress. Therefore, in the present study, the alleviating role of exogenously applied glutamic acid was examined in soil grown cucumbers (Cucumis sativus L.) under four levels of cadmium (0, 5, 10, and 20 mg Cd/kg) and two levels of glutamic acid (0,...
The protective effect of cold acclimation on the low temperature stress of the lotus (Nelumbo nucifera)Original Paper

This study compared the protective effect of cold acclimation on the cold tolerance in the lotus (Nelumbo nucifera). The cold acclimation increased the sprouting rate and leaf expansion rate of the lotus by about 36% at 0 °C, and the cold acclimation could enhance the levels of the stress related osmolytes including higher proline, soluble protein, and soluble sugar contents. The electrolyte leakage and lipid peroxidation level of the control samples increased significantly, but these indices did not change significantly in the cold acclimation group during low temperature stress. Furthermore, the cold acclimated rhizomes had higher antioxidant...

Flower vase life is one important aspect in determining the flower quality in the cut flower chrysanthemum. The use of ascorbic or salicylic acid as preservative solutions was expected to have an impact on the prolonged duration of the cut flower freshness. The research was designed in two parallel experiments. The first dealt with salicylic acid, while the second focused on ascorbic acid. Both experiments were arranged in a factorial completely blocked randomised design. Two chrysanthemum varieties, i.e., 'Reagent Sunny' and 'Yellow Fiji' were the first factor and concentrations of the salicylic or ascorbic acids, i.e., 0, 100, 200 and 300 ppm became...
Effect of activated charcoal and ascorbic acid on in vitro morphogenesis and o-dihydroxyphenols content in Paphiopedilum insigneShort Communication

Phenolic compounds limit micropropagation of many orchids in vitro. The aim of the study was to estimate the effect of activated charcoal (AC);1, 2 or 4 g/L) or ascorbic acid (AA; 10, 20 or 30 mg/L) added to the half strength MS medium on the growth and o-dihydroxyphenols content in Paphiopedilum insigne in vitro. A positive effect of AC on the shoot and root formation has been found. The highest multiplication rate (5.6 shoots/explant) and rooting frequency were obtained on medium containing 2 g/L of AC. However, AC reduced the leaf number as compared to the control. The lowest content of o-dihydroxyphenols was marked in Paphiopedilum insigne leaves...

A field experiment was undertaken in a vineyard in southern Romania to evaluate the insect species abundance in this temperate climate area, over a period of 24 consecutive weeks, starting from April 2nd to September 27th, 2019. A total number of 19 303 insects were collected. After their morphological analysis, 89 species of insects were identified (nine orders and 28 families), of which 52 came from beneficial fauna (six orders and 14 families, 1 316 individuals) and 37 came from pest fauna (six orders and 26 families, 17 987 individuals). The beneficial species richness of the Coleoptera and Hymenoptera orders were the best...
