Abstract:

China has the largest sweet potato planting area worldwide, as well as the highest yield per unit area and total yield. Drought is the most frequently encountered environmental stress during the sweet potato growing season. In this study, we investigated salicylic acid (SA)-mediated defense mechanisms under drought conditions in two sweet potato varieties, Zheshu 77 and Zheshu 13. Drought stress decreased growth traits, photosynthetic pigments and relative water contents, as well as the photosynthetic capability parameters net photosynthetic rate, stomatal conductance and transpiration rate, w

Abstract:

Terminal drought is a major threat that adversely affects crop growth and metabolism, and limits the yield. Water stress causes many morphological, physiological and biochemical changes in plants. Plant height, root length, leaf area, fresh and dry biomass are reduced under drought stress. Besides, water stress causes the reduction of relative water content, the closure of stomata and decrease in photosynthesis and chlorophyll content. Antioxidant enzymes such as glutathione reductase (GR), superoxide dismutase (SOD), peroxidase (POD), ascorbat peroxidase (ASC), glutatiton (GSH), catalase (CAT

Abstract:

Biosynthesis and accumulation of flavonolignans in plants are influenced by different environmental conditions. Biosynthesis and accumulation of silymarin in milk thistle (Silybum marianum L.) were studied under drought stress with respect to the antioxidant defense system at the physiological and gene expression level. The results revealed a reduction in leaf chlorophyll, ascorbic acid, and glutathione contents. In contrast, H2O2, proline, and antioxidative enzyme activities, such as superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), ascorbate peroxidase (APX), and glutathione redu

Abstract:

Adverse environmental factors like drought stress result in increased levels of ROS that adversely affect the growth and productivity of plants. The alleviation of oxidative damage and increased resistance to environmental stresses is correlated with an efficient antioxidant system. Antioxidant non enzymatic system as well as enzymatic system neutralize the effects of these reactive oxygen species and help plants to survive in stress conditions. The study was carried out with the aim to understand the effect of drought on antioxidant system in seedling and vegetative stages of drought tolerant

Abstract:

Exposure of banana plants, one of the most important tropical and subtropical plants, to low temperatures causes a severe drop in productivity, as they are sensitive to cold and do not have a strong defense system against chilling. Therefore, this study aimed to improve the growth and resistance to cold stress of banana plants using foliar treatments of chitosan nanoparticles (CH-NPs). CH-NPs produced by nanotechnology have been used to enhance tolerance and plant growth under different abiotic stresses, e.g., salinity and drought; however, there is little information available about their eff

The purpose of the study is to assess the physiological and antioxidant parameters of sunflower seedlings under osmopriming. Two series of experiments were carried out aimed at: 1) establishing the viability of seeds; 2) assessment of physiological parameters of seedlings. Each experiment included a group of control samples grown under conditions of sufficient moisture and four impact groups exposed to varying levels of osmotic stress. The intensity of accumulation of lipid peroxidation products and the rate of accumulation of reactive oxygen species were determined based on the reaction of ma

<strong>ABSTRACT</strong> Biotic and abiotic stresses exert a considerable influence on the growth and physiology of plants. Water stress is one of the most important abiotic stress factors. The study was carried out to elucidate the effect of drought stress on growth, physiology and antioxidant enzyme activity of <em>Cassia occidentalis </em>experiencing four water regimes with soil relative water content ranging from 65% to 12%. Plants were grown in pots and treated with three irrigation levels (100ml, 200ml and 300ml).The experiment was laid out in complete randomized design (CRD) with thre

Abstract:

Reactive Oxygenspecies (ROS) cause free radical peroxidation of macromolecules (FRPO). The formation of malonic dialdehyde (MDA) is the marker of FRPO, and the consequences of changes in prooxidant-antioxidant system (PAS) are evidenced by changes in the activity of the enzyme cytochrome oxidase. The study of the role of ROS in anti-infective protection of animals, oxidative explosion processes, mechanisms of aging and apoptosis has opened up the prospects for the search for analogues in the plant world. Quantitative determination of PO and FRPO products was carried out on grains of Zea mays L

Abstract:

Kiwifruit is a vine fruit tree that is vulnerable to water deficiency due to its shallow root system and large leaves. Although mycorrhizal inoculation and melatonin application has been proved to improve plants drought tolerance, their interaction effects are still unclear. In this study, arbuscular mycorrhizal (AM) fungi incubation and melatonin (MT) irrigation were applied to kiwifruit seedlings alone or in combination to investigate their effect on drought tolerance. The results revealed that AM had more effect on promoting root biomass, water use efficiency, and uptake of nitrogen, phosph
