The nutrient-limiting conditions in saline–alkali soil as well the salinity and alkalinity stress are successfully alleviated by water management measures addition of organic matter. However, impacts these two strategies on microbe-driven CO2 emissions saline–alkaline soils not yet clear. Therefore, a 150-day incubation experiment was conducted this study to evaluate short-term effects regulati...

The morphological plasticity of plant roots is a key factor in their ability to tolerate wide range edaphic stresses. There are many unanswered questions relating nanotechnology and its potential uses for sustainable agriculture. main purpose this study was examine the effects salinity-induced morphogenic responses zinc oxide nanoparticles (ZnO-NPs) on root characteristics, growth, MDA content,...

A pot experiment was carried out to determine the effect of foliage spraying of silicon (Si) on growth and ornamental characteristics of calendula grown under salt stress and greenhouse conditions. A factorial experiment based on completely randomized design was conducted with 3 levels of Si (0, 50 and 100 mg/l) and 3 levels of NaCl (0, 100 and 200 mM) with 4 replications. At flowering stage, S...

The present work has been conducted to study the impact of Zn (20 and 200 μM) or Ni (1 100 on growth, metabolic activities, osmotic pressure heavy metal wheat cultivar (cv. Gimiza 11) under salt stress conditions. Harvest index was significantly decreased by 75% at -0.3 MPa -1.2 53%. Length root, stem spike, leaf area were slightly reduced up -0.9 NaCl level, after that a significant reduction ...

Pot greenhouse experiments were carried out to attempt to increase the salinity tolerance of one of the most popular legume of the world; cowpea; by using dual inoculation of an Am fungus Glomus clarum and a nitrogen-fixer Azospirillum brasilense. The effect of these beneficial microbes, as single- or dual inoculation-treatments, was assessed in sterilized loamy sand soil at five NaCl levels (0...

Acclimated and acute rates of oxygen consumption of the American oyster Crassostrea virginica (Gmelin) were measured under 9 salinity-temperature combinations during declining oxygen tensions. In acclimated and non-acclimated individuals the basal rate of oxygen uptake increased significantly with each 10 C" rise in temperature. Multiple regression equations relating exposure and experimental t...

The present investigation was aimed at determining the effects of arbuscular mycorrhiza on growth and yield of chilli plants grown under salinity condition. Seeds of chilli were sown in sand beds in size 5×1m under shade net condition at Botanical Garden, Department of Botany, Annamalai University. Forty days old seedlings (DAS) were transplanted into pots (one seedling per pot) until the fruit...
