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...

Plant growth and development are adversely affected by salinity – a major environmental stress that limits agricultural production. This chapter provides an overview of the physiological mechanisms by which growth and development of crop plants are affected by salinity. The initial phase of growth reduction is due to an osmotic effect, is similar to the initial response to water stress and show...

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...

the development of seminal and lateral root system plays a major role in plant access to water and nutrients under abiotic stress, especially salinity. in order to understand the relation between root growth responsesand shoot physiological indices oftwo bread wheat cultivars contrasting in salt tolerance (kavir and shiraz), a greenhouse experiment was conducted with two salinity levels (0 and ...

Continuous desertification of arable lands mandates use of low quality/ saline water for irrigation, especially in regions experiencing water shortage. Using low quality/ saline water for irrigation imposes more stress on plants that are already under stress in these regions. Thus, a logical solution will be to find a salt/ drought-tolerant plant species that will survive/sustain under such str...

Ornithine is a non-proteinogenic amino acid, which plays an essential role in the metabolism of plants. Regard to the chirality of the molecule, physiological response of the plant cells to its two enantiomers have not been widely investigated yet. In the present study, suspension-cultured tobacco cells were treated with 1 mM of D- and Lenantiomers of ornithine in normal conditions as well as u...

lentil is considered as salinity sensitive species and is adversely affected in response to the salt stress in terms of growth and yield. this pot experiment was conducted to determine the effect of exogenous salicylic acid (sa) application on physiology, growth, yield and yield components of lentil grown under salt stress in greenhouse conditions, in a factorial arrangement based on randomized...
