Salinity poses a major threat for agriculture worldwide. Rice is one of the major crops where most of the high-yielding cultivars are highly sensitive to salinity. Several studies on the genetic variability across rice cultivars suggest that the activity and composition of root plasma membrane transporters could underlie the observed cultivar-specific salinity tolerance in rice. In the current ...

This study aimed to investigate the effects of mild salinity stress on some physiological traits and metabolic profiles rice during seedling stage. Three cultivars differing in response, ‘KDML105’ (salt-sensitive, local Thai jasmine rice), ‘IR29’ (salt-sensitive ‘Pokkali’ (salt-tolerant were subjected by flood-irrigated with 40 mM NaCl. Salinity significantly reduces growth biomass sensitive cu...

The effects of exogenous ascorbic acid (AsA) and reduced glutathione (GSH) on antioxidant enzyme activities [superoxide dismutase (SOD), ascorbate peroxidase (APX), and glutathione reductase (GR)] and the contents of malondialdehyde (MDA) and H2O2, as well as of endogenous AsA and GSH, in the chloroplasts of two rice cultivars, the salt-tolerant cultivar Pokkali and the salt-sensitive cultivar ...

An experiment was conducted to study the effect of growth regulators on callus induction in rice embryo culture. In this experiment, caullogenesis was initiated from the matured seeds of seven indica rice varieties viz., TRY 1, TRY 2, Pokkali, CSR 10, W.Ponni, BPT 5204 and IR 29. The medium used for this callus induction was Murashige and Skoog (1962) commonly referred as MS medium with six dif...

Background: Pokkali is a versatile rice- fish system of cultivation, producing naturally organic rice along the waterlogged coastal regions Kerala. The weed flora fields different from other ecosystems. Diverse appears in low saline phase, when cultivated, but they dry up and decompose high phase. With time, significant deviations have been reported various climatic parameters as result, spectr...
