Abstract The purpose of the present study is to investigate role hydrogen sulfide (H 2 S), in improving resistance common bean salt stress. Method shows that seeds were soaked water and two concentrations sodium hydrosulfide (50 100 µM) for 8 h. After 25 days from sowing, pots irrigated with NaCl (75 150 mM) until end experiment. Results revealed H S relieved stress by decreasing growth inhibit...

Trehalose, as a non-reductive disaccharide, plays vital role in plant growth and development resistance to abiotic stress. Trehalose-6-phosphate synthase (TPS) is key enzyme the synthesis mechanism of trehalose TPS1 genes play crucial response stress plants. However, it has rarely been reported that CaTPS1 responds cold salt stresses pepper. To verify function stresses, was silenced by virus-in...

The current study investigated the effects of Pseudomonas putida strain KT2440 on drought tolerance tomato plants during fruit maturation. Plants at ripening stage mature-green were not watered for 20 days to promote stress. Concentrations photosynthetic pigments determined. Bacteria-soaked (BSS) had higher levels chlorophyll and carotenoids than non-soaked (DWS) under stress conditions. Compar...

The combined effect of salicylic acid (SA) (100, 200 and 400 ppm) and water stress (waterlogging and drought) on growth, reactive oxygen species generation and activities of enzymatic and non-enzymatic antioxidants were studied in soybean (Glycine max L. Merr.) leaves.The results proved that the interaction of salicylic acid with water stress significantly increased total protein content and de...

Protocorm-like bodies (PLBs) of Brassidium Shooting Star orchid were successfully cryopreserved using droplet-vitrification method. Vitrification based cryopreservation protocol is comprised of preculture, osmoprotection, cryoprotection, cooling, rewarming, and growth recovery and each and every step contributes to the achievement of successful cryopreservation. In order to reveal the lethal an...

Pot experiments were conducted to evaluate the damaging effects of salinity on Sesbania sesban plants in the presence and absence of arbuscular mycorrhizal fungi (AMF). The selected morphological, physiological and biochemical parameters of S. sesban were measured. Salinity reduced growth and chlorophyll content drastically while as AMF inoculated plants improved growth. A decrease in the numbe...

Cyanobacteria contribute significantly to the maintenance of flooded rice field fertility. In this investigation, the protective effect of osmolytes and antioxidative enzymes was studied on the paddy field cyanobacterial biofertilizer; Anabaena variabilis exposed to Malathion pesticide. With increasing concentration of malathion the test organism showed increased free radical mediated toxicity....

drought stress is one of the phenomena that adversely affects growth and quality of plants, with turfgrass being no exception. for a study of the responses of poa pratensis l. cv. ’barimpala‘ to time periods of drought stress, turfgrass seeds were cultivated at 60cm depths in cylindrical pots of 15cm diameters and placed outdoors. plants were daily irrigated to the point until drainage occurred...

In present study, we evaluated the effects of Jasmonic acid (JA) on physio-biochemical attributes, antioxidant enzyme activity, and gene expression in soybean (Glycine max L.) plants subjected to nickel (Ni) stress. Ni stress decreases the shoot and root length and chlorophyll content by 37.23, 38.31, and 39.21%, respectively, over the control. However, application of JA was found to improve th...

Selenium (Se) contamination due to industrial activities has received increasing concerns. Phytoremediation has been suggested to be an efficient and feasible way to remove Se from Se-contaminated environment. Recently, an arsenic (As) hyperaccumulator Pteris vittata L. (Chinese Brake fern) was found to be a Se accumulator. This study was carried out to investigate Se accumulation mechanisms co...
