an enzyme electrode was developed using the enzyme sulfite oxidase (ec1.8.3.1) immobilized onto pig intestine. hydrogen peroxide produced was monitored amperometrically. all experimental parameters such as ph, temperature, buffer constituent concentration, were thoroughly investigated and optimized when appropriate. the response to sulfite concentration was linear in the range 5.2´10-6 to 1.02´...

Salt stress is one of the most significant abiotic stresses that substantially negatively impact plant growth and productivity. However, a slew research thus far has investigated ameliorating properties arbuscular mycorrhizal (AM) symbiosis their potential to improve tolerance salt stress. The present study aimed evaluate compare role inocula obtained from Sabkha (S-AMF) non-Sabkha (NS-AMF) hab...

the role of zinc (zn) in enhancing defense capacity of several plants against salinity has been demonstrated but there is limited information on the impact of zn nutrition on alleviating salinity-induced oxidative damage in olive. one-year-old seedlings of two varieties of olive (olea europaea l. cvs. frontoio and conservolea) supplied with three zn levels (0, 1 and 5 mm in the form of znso4.7h...

This study simulated outdoor environmental living conditions and observed the growth rates and changes of several photosynthetic pigments (Chl a, Car, PE, and PC) in Hypnea cervicornis J. Agardh (Gigartinales, Rhodophyta) by setting up different ranges of salinity (25, 30, 35, 40, 45, and 50) and temperature (15, 20, 25, and 30°C). At conditions of culture, the results are as follows. (1) Chang...

Salinity is a major environmental stress that limits crop production worldwide. In this study, we characterized plant growth-promoting rhizobacteria (PGPR) containing 1-aminocyclopropane-1-carboxylate (ACC) deaminase and examined their effect on salinity stress tolerance in okra through the induction of ROS-scavenging enzyme activity. PGPR inoculated okra plants exhibited higher germination per...

Salinity stress is the most widespread and the most severe abiotic stress that plants face. More than 800 million hectares worldwide, representing more than 6% of world's land area, are affected by salinity. Tomato is one of the most important horticultural crops. However, due to the progressive salinization of irrigated land, areas for optimal growth of tomato are being reduced all over the wo...

in order to investigate the effect of mycorrhizal fungi and phosphorus fertilizer on concentration of leaf nutrients and photosynthetic pigments of bean (phaseolus vulgaris l.) in condition of irrigation with saline water, an experiment was conducted based on completely randomized design with three replications in greenhouse of bahonar university of kerman, iran during 2010. the studied factors...

Anthurium andreanum was one of the best indoor ornamental plants. Two cultivars (Pink Champion, Alabama) were used to investigate effects light quality on physiological and biochemical indexes. There six different treatments: Fluorescent Daylight Lamp (CK), RB (100% Blue, 60% R + 40% B, 70% 30% 80% 20% 100% Red) provided by emitting diodes (LED). The results showed that blue beneficial shoot gr...

Chloroplasts and photosynthesis are the physiologically fateful arenas of salinity stress. Morphological anatomical alterations in leaf tissue, ultrastructural changes chloroplast, compromise integrity three-layered chloroplast membrane system, defects light dark reactions during osmotic, ionic, oxidative phases salt stress conversed detail to bring salinity-mediated physiological on a single p...
