Abstract
This study leads with the primed seeds of rice (var. Swarna) with distilled water (D.W.) and various concentrations of Mg(NO3)2 (0-8 mM)/Kinetin (0-5 ppm) alone or in combination with screen out the regeneration medium induced tolerance level of NaCl. To fulfill the objective, the primed and non-primed rice seeds were inoculated in MS medium supplemented with 30 gL-1 maltose + 1 gL-1 casein hydrolysate and 2 mgL-1 of 2,4-D for callus induction and cultured up to 45 days in two sets: one set for regeneration purpose in NaCl-induced regeneration medium and another set was used to study the physiological potentiality of the callus. The 45-day-old calli were transferred into regeneration medium MSR (MS medium for regeneration) (BAP: NAA: Kinetin = 4:1:1) containing NaCl with a concentration range of 0 to 300 mM. The number of regenerating calli and shoot regeneration percentage, number of plantlets obtained from one callus, recovery of plantlets from each concentration of NaCl and proline estimation from the leaf of the regenerated plantlets were determined from one set obtained after 45 days. The calli obtained from another set after 45 days, the frequencies of total and embryogenic calli induction percentage, fresh and dry weights, proline content, nitrate reductase and superoxide dismutase activities were measured. The calli obtained from 2.5 ppm kinetin + 4 mM Mg(NO3)2 primed seeds were showed best result as compared to the other treatments for the above-mentioned parameters in different concentrations of NaCl-induced medium and survive up to 200 mM concentrations of NaCl.

期刊介绍:
How can the scientific knowledge we possess now influence that future? That is, the FUTURE of Earth and life − of humankind. Can we make choices in the present to change our future? How can 21st century biological research ask proper scientific questions and find solid answers? Addressing these questions is the main goal of Biologia Futura (formerly Acta Biologica Hungarica).
In keeping with the name, the new mission is to focus on areas of biology where major advances are to be expected, areas of biology with strong inter-disciplinary connection and to provide new avenues for future research in biology. Biologia Futura aims to publish articles from all fields of biology.
