5. Conclusion
In this study, we focused on growth and seed yield when Camelina was grown in water deficit condition and symbiosis with Micrococcus yunnanensis . From our finding, it can be concluded that Camelina yield is significantly affected by water-deficit stress in the reproductive stage. The enhancement of seed weight coincided with the increase of protein and carbohydrate content when Camelina was disposed of water deficit while the decrease of the seed and silique number was associated with water deficit compared with control. It confirmed the previous finding that the proportion of oil and protein alter adversely in the developing seed due to disparate partition of nutrients in particular carbon and nitrogen in the various environmental condition. In the fatty acid profile, the most proportion was related to PUFA in particular linolenic acid (18:3) by 50%. Saturated fatty acid and polyunsaturated fatty acid content were relatively parallel when Camelina was grown in water deficit stress. Similar to oil, monounsaturated fatty acid content reduced in stressed plants. In Camelina seed, phosphorus content and N: S ratio positively correlated to protein content and increase of antioxidant capacity in the response to water deficit stress. Besides, micronutrients (Fe, Mn, and Zn) significantly increased under water-limited conditions. Based on the science of the PGPB exhibited various changes in the growth and the physical and biochemical trait Camelina in both of the well-watered and water-limited.
