Salt and PEG Induced Osmotic Stress Tolerance at Germination and Seedling Stage in Camelina sativa: A Potential Biofuel Crop

Patade Vikas Yadav , Deepti Khatri and Mohammed Nasim

Abstract:
Background: Camalina sativa L. (Crantz), a non-edible oilseed crop has been introduced in India as a potential feedstock for biofuel production. In order to avoid resource sharing with food crops, Indian National Biofuel Policy states that biofuel crops are to be cultivated only on marginal degraded lands. Therefore, the present investigation was designed to study salt and osmotic stress tolerance in Camelina. Materials and Methods: In the present investigation, salt (NaCl 50, 100, 150, 200, 250 or 300 mM) or polyethylene glycol 6000 (PEG 6000; 5, 10, 15 or 20% w/v) induced osmotic stress tolerance at germination and on seedlings of C. sativa cv. Calena was studied. Results: Seed germination or opening of cotyledonary leaves was not affected by treatment with up to 150 mM NaCl. When treated with 20% PEG, seed germination was not inhibited, however, percent and rate of opening of cotyledonary leaves was reduced. Treatment of seedlings with 150 mM NaCl for 11 days resulted in no differences in growth and relative water content compared to the untreated control seedlings. Treatment with PEG affected growth and relative water content compared to the control. Relative water content was reduced and membrane damage significantly increased in PEG treated seedlings over the control or NaCl treated seedlings. Conclusion: Thus, the results suggest that Camelina cv. Calena is tolerant to salt (NaCl, 150 mM) and may be suitable for cultivation under salt affected areas for biofuel production.
