Effect of Selenium on Growth, Physiological and Biochemical Indices of Garlic Plant (Allium sativum) under Cadmium Toxicity
Increasing the tolerance of plants to biotic and abioticts stresses is a important and debatable subject. Selenium can play a role in mitigating the effects of stress. For this purpose, a factorial experiment was conducted in a completely randomized design with two treatments, cadmium chloride including two levels (0 and 10 mg /kg) in soil and sodium selenate involved three levels (0, 500 and 1...
متن کاملArsenic Uptake, Toxicity, Detoxification, and Speciation in Plants: Physiological, Biochemical, and Molecular Aspects
Environmental contamination with arsenic (As) is a global environmental, agricultural and health issue due to the highly toxic and carcinogenic nature of As. Exposure of plants to As, even at very low concentration, can cause many morphological, physiological, and biochemical changes. The recent research on As in the soil-plant system indicates that As toxicity to plants varies with its speciat...
متن کاملAn Overview of Selenium Uptake, Metabolism, and Toxicity in Plants
Selenium (Se) is an essential micronutrient for humans and animals, but lead to toxicity when taken in excessive amounts. Plants are the main source of dietary Se, but essentiality of Se for plants is still controversial. However, Se at low doses protects the plants from variety of abiotic stresses such as cold, drought, desiccation, and metal stress. In animals, Se acts as an antioxidant and h...
متن کاملSemitendinosus regrowth: biochemical, ultrastructural, and physiological characterization of the regenerate tendon.
BACKGROUND Previous studies have suggested that hamstring tendons can regenerate following harvesting for anterior cruciate ligament reconstruction. HYPOTHESIS This "neo-tendon" is a true, functional tendon, not scar tissue. STUDY DESIGN Controlled laboratory study. METHODS Semitendinosus tendons were harvested from 35 New Zealand white rabbits using a standard tendon stripper. The rabbit...
متن کاملSeasonal changes in some physiological and biochemical responses of six groundcover plants
Landscape groundcover plants are a diverse group of trailing or spreading species that naturally form continuous soil coverage.Ground cover plants that were used in this study consisted of vegetative propagules of: Vinca minor L. ٬Variegatum’, Vinca minor L. ٬Green’, Oxalis brasiliensis G. Lodd, Trifolium repens L., Phyla nodiflora L. and Frankenia thymifolia Desf. The aim of this study was to ...
