This study aimed to evaluate the effects of priming on seed germination under salt stress and gene expression in seeds and seedlings of P. angulata L. After priming for 10 days, seed germination was tested in plastic trays containing 15 ml of water (0 dS m-1 - control) or 15 ml of NaCl solution (2, 4, 6, 8, 10, 12, 14 and 16 dS m-1). Fresh and dry weight of shoots and roots of seedlings were ev...

The present study investigates the effect of soil amended with sewage sludge on oxidative changes in zucchini and cucumber plants (Cucurbitaceae) and the consequent activation of their antioxidative systems and detoxification mechanisms. The plants were grown in pots containing soil amended with three concentrations of sewage sludge (1.8 g, 5.4 g and 10.8 g per pot), while controls were potted ...

In Cameroon, tomato yields remain low due to attack by pathogens and insects. Phytophtora infestans (PI) is a phytopathogenic fungus responsible for the downy mildew of tomatoes, fungal disease enormous economic losses. To contribute search means control, stimulatory effect defence system extracts some plants was evaluated. Tomato were treated with aqueous macerates Callistemon citrinus (C. cit...

ABSTRACT The study focusses on alternative substrates with the potential to replace common substrates, such as mineral wool and perlite, influence of these ecosystems resources is being debated. To this aim, wood fibre, sheep coco peat were selected for testing. Leaf lettuce ( Lactuca sativa L. ‘Lisboa’) taken model crop evaluation substrates. closed hydroponic system ebb flow growing in pots w...

To understand the adaptability of alfalfa (Medicago sativa L.) to environmental stresses, we analyzed the activity of several antioxidant enzymes, including superoxide dismutase (SOD), peroxidase (POD), ascorbate peroxidase (APX), and catalase (CAT), in alfalfa shoots and roots subjected to salt and drought stresses during germination. The germination rate of six alfalfa cultivars was comparati...

Background: How plants respond to stress conditions can play an important role in the establishment and increasing crop yield. The results of researchers’ reports indicate that extensive morphophysiological biochemical changes occur under drought conditions. This study aimed investigate effects ascorbic acid (AA) calcium carbonate (CC) on guar different soil moisture Methods: experimental treat...

To investigate whether Cd induces common plant defense pathways or unspecific necrosis, the temporal sequence of physiological reactions, including hydrogen peroxide (H(2)O(2)) production, changes in ascorbate-glutathione-related antioxidant systems, secondary metabolism (peroxidases, phenolics, and lignification), and developmental changes, was characterized in roots of hydroponically grown Sc...
