Growth And Yield

Salinity stress is a limiting factor for the growth and yield quality of rapeseed. The potentiality of melatonin (MT; 0, 25, 50, and 100 µM) application as a seed priming agent in mediating K+/Na+ homeostasis and preventing the salinity stress mediated oxidative damage and photosynthetic inhibition was studied in two rapeseed cultivars. We found that 50 µM MT treatment imparted a very prominent impact on growth, metabolism of antioxidants, photosynthesis, osmolytes, secondary metabolites, yield, and fatty acids composition. Days required for appearance of first flower and 50% flowering were decreased by MT application. Exogenous MT treatment effectively decreased the oxidative damage by significantly declining the generation of superoxide and hydrogen peroxide under saline and non-saline conditions, as reflected in lowered lipid peroxidation, heightened membrane stability, and up-regulation of antioxidant enzymes (catalase, superoxide dismutase, and ascorbate peroxidase). Furthermore, MT application enhanced the chlorophyll content, photosynthetic rate, relative water content, K+/Na+ homeostasis, soluble sugars, and proline content. Moreover, MT application obviously improved the oil quality of rapeseed cultivars by reducing glucosinolates, saturated fatty acids (palmitic and arachidic acids), and enhancing unsaturated fatty acids (linolenic and oleic acids except erucic acid were reduced). Yield related-traits such as silique traits, seed yield per plant, 1000 seeds weight, seed oil content, and yield biomass traits were enhanced by MT application. The anatomical analysis of leaf and stem showed that stomatal and xylem vessels traits are associated with sodium chloride tolerance, yield, and seed fatty acid composition. These results suggest the supportive role of MT on the quality and quantity of rapeseed oil yield.

This paper aims to determine the content of bioactive substances of lipid fractions extracted from Bertholletia excelsa, Lecythis pisonis and Dipteryx lacunifera, in by the interest of better identifying the quality of these raw materials. Proximate composition of nuts was determined by official methods and total carbohydrate was calculated by difference. The oils were extracted from the nuts by cold pressing and analyzed for fatty acid composition, tocopherols, phytosterols and total carotenoids and phenolics compounds. The fatty acid composition of oil extracted from L. pisonis was more unsaturated compared with others oils. L. pisonis oil showed to be richer in total tocopherol and γ-tocopherol, moreover showed considerable total phytosterol and carotenoid amounts, thus representing an important source of vitamins A and E. The oils showed significant content of phenolic compounds, with the exception of the oil extracted from D. lacunifera. The study revealed that the oils from Brazilian nuts contain bioactive compounds in relevant quantities, L. pisonis oil standing out. This fact favors their use for food and, as raw material in chemical, pharmaceutical and cosmetic industries, adding value to products derived from these oils, increasing the viable sources of raw materials.
