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.
