The objective of this study was to evaluate the use lemon essential oil and its mixtures with chitosan, calcium chloride, natamycin on postharvest storage quality citrus. analysis physiological biochemical index changes citrus stored at 20 ± 2 °C 75 5% relative humidity for 60 days showed that could help maintain nutritional sensory In addition, increased activities superoxide dismutase (SOD), ...

the effect of salinity was assessed on the activity of some major antioxidant enzymes i.e., superoxide dismutase (sod), peroxidase (pod), catalase (cat), in the seedlings’ roots or shoots of three winter canola (brassica napus l.) cultivars, colvert (tolerant), symbol (semi tolerant) and agat (susceptible). seedlings were treated with 0 (control), 50, 100 and 150 mm nacl for 24 h in hydropoic c...

BACKGROUND Podcasting is currently a popular means of delivery of information with a large number of podcasts specifically tailored for educational purposes. It can be argued that the passive nature of this teaching methodology limits the educational benefit that can be derived from podcasts. This paper describes the development and construction of interactive material for the iPod, and a surve...

Abstract In this study, we investigated the physiological responses of maize with different amylose content at seedlings to drought stress. For waxy (WMS) and normal (NMS), decline photosynthesis under stress (DS) was due stomatal limitation. DS increased non-photochemical quenching coefficient (NPQ), whereas decreased activities peroxidase (POD) plant height (PH), compared plants irrigation. T...

Abstract The objective of this work was to validate the enzymatic activity in Annona x atemoyaseeds submitted treatments with plant growth regulators belonging group gibberellins and cytokinins for overcoming dormancy during germination process. Initially, water acquisition curve determined, where two points phase II (72 144 hours) were determined evaluate superoxide dismutase (SOD), peroxidase...

The therapeutic effect of chemodynamic therapy (CDT) is significantly restricted by the stern reaction conditions and slow rate Fenton (pH 3-4). Herein, we report an ultrasmall trimetallic (Pd, Cu, Fe) alloy nanozyme (PCF-a NEs) possessing dynamic active-site synergism, thus exhibiting a cascade glutathione peroxidase (POD) mimicking activities in circumneutral pH. PCF-a NEs exhibit phototherma...

water deficit stress is the most important environmental constraint for growth, yield and productivity of crops, including the oil seed crops. this study was aimed at studying the influence of differing irrigation régimes on growth, chlorophyll , proline and some antioxidants content along with grain yield, yield components and oil content of sesame genotypes using a 4-replicate split plot rand...

Cadmium (Cd) is considered as phytotoxic in nature, its toxicity on the plant development decrease antioxidative enzymes activities under stress environment. Castor (Ricinus Communis L.) a metal tolerant and ability to survive highly polluted soils. exhibited high level of Cd soil buildup antioxidants i.e., super oxide dismutase (SOD), peroxidase (POD) malondialdehyde (MAD) top ground parts str...

drought is an important abiotic stress limiting plant performance. generation of reactive oxygen species (ros) is enhanced under stresses. two greenhouse experiments were conducted to evaluate the effect of phytohormones on the changes of antioxidant enzymes and carotenoids in petals of pot marigold (calendula officinalis l.) under drought stress. results showed that the activities of superoxid...

Storage of Lime (Citrus aurantifolia L.) fruits, originally a tropical fruits, in low temperature confronts with several difficulties  due to the risk of chilling injury (CI). To develop an effective method aiming to  reduce CI, the effects of treatments containing 0, 0.5 and 1 Mg/lit brassinosteroids (BRs) and hot water (HW) including 20°C as control, 45 and 55°C for 30 minute on CI was studie...
