To provide theoretical basis and technical support for the planting and cultivation of Camelina sativa under stress and clarify the effects of branched chain amino acids(BCAAs) on Camelina sativa seed germination under drought and salt stress. In this study, SC-N16, a cultivate of Camelina sativa, was used as material. The drought stress and salt stress models were established using polyethylene glycol 6000(PEG) and sodium chloride(NaCl). And then leucine(Leu), isoleucine(Ile), and valine (Val) solution were selected to soak the seed of Camelina sativa. Statistical analysis of the effects of BCAAs to the germination indexes of Camelina sativa, including germination rate, germination potential, germination index, root length, bud length, fresh weight, and dry weight was conducted. The results showed that when the model of drought stress and salt stress was 0.20 g/mL of PEG and 150 mmol/L of NaCl respectively. The seed germination ability of Camelina sativa was improved through the treatment of three BCAAs. Among them, the best alleviation effect of BCAAs on seeds germination was observed with the treatment of 100 μmol/L Valine. Compared with the model of drought stress, its germination potential and germination rate increased by 164.78% and 34.76%, respectively. Compared with the model of salt stress, those two indexes increased by 36.98% and 29.77%, respectively. When the concentration range of Val was further expanded in from 0 to 250 μmol/L, the alleviation effect of Val on Camelina sativa seed germination under drought and salt stress showed a trend of first increase and then decrease as the increase of Val concentration. In particularly, the optimal concentration of Val was remained at 100 μmol/L. Compared with drought stress by PEG, the root length, bud length, dry weight, and fresh weight increased by 19.61%, 30.77%, 28.66% and 9.53%, respectively. Compared with salt stress by NaCl, the indexes increased by 21.05%, 38.63%, 27.14% and 7.83%, respectively. In conclusion,under the stress of drought and salt, when the exogenous BCAAs was Val and its concentration was 100 μmol/L, the alleviating effect on seed germination of Camelina sativa was optimal.
