ferulago angulata (apiaceae), a medicinal plant of western asia, contains essential oils that areused as a food preservative. this study examined and compared the composition of leaf oil with seed oil andof the oils from two different habitats (one from nevakov and the other from shahoo). the oil yield from seedwas 5-fold that from leaves (3.2%/100g compared to 0.63%/100g). cis-ocimene was the ...

Genes involved in fatty acids biosynthesis, modification and oil body formation are expected to be conserved in structure and function in different plant species. However, significant differences in the composition of fatty acids and total oil contents in seeds have been observed in different plant species. Comparative genomics was performed on 261 genes involved in fatty acids biosynthesis, TA...

Soybean (Glycine max L.) seed is a major source of protein, oil, carbohydrates and other nutrients that are important for human and animal nutrition. Producers have considered applying nitrogen (N) fertilizer to soybean crop to maximize seed yield; however, its effect on seed composition is not well understood. The objective of this two-year (2015 and 2016) study was to evaluate the effects of ...

seed loss at harvesting time is one of the factors reducing seed yield in at farms. this study was carried out within a research farm in karaj to evaluate and select a proper pinto bean line for mechanized harvesting at two moisture contents during harvesting and their effect on seed yield and yield loss among three lines of pinto bean. the experiment was split-plot based on randomized complete...

BACKGROUND The aim of this study was to evaluate the effects of nitroxin biofertilizer and chemical fertilizer on the growth, yield, and essential oil composition of dill. The experiment was conducted under field condition in randomized complete block design with three replications and two factors. RESULTS The first factor was the concentrations of nitroxin biofertilizer (0%, 50%, and 100%) o...

Soybean oil contains 14 fatty acids and five of them, C16:0, C18:0, C18:1, C18:2, and C18:3, are considered essential fatty acids for proper human nutrition. Increasing the oil content and improving the ratio of the various fatty acids in soybeans is a goal for many breeding programs. The objective of this research was to evaluate the relationship between grain yield, oil content, and fatty aci...

Temperature and pressure effects of supercritical carbon dioxide (SCCO2) on the extraction of carotenoids and seed oil from rosehip fruits have been studied. Supercritical fluid extraction (SFE) has shown much potential skills for the isolation of organic compounds from various samples. SFE minimizes sample handling, provides fairly clean extracts, expedites sample preparation and reduces the u...
