Abstract:

Camelina is one of the plants that it seed yield is highly dependent on planting date. This experiment was conducted using randomized complete blocks design with three replications in research farm of Fasa Branch, Islamic Azad University, Fasa, Iran in 2018 and 2019 cropping seasons. Planting dates at six levels; November 1, 11, 21 (autumn sowing) and February 20, March 1 and 11 (winter sowing). The results showed that the autumn planting on November 1 (with 1550 GDD) had the highest seed yield (2373 kg.ha-1) and oil yield (621.kg ha-1). Harvest index of autumn planting was 4.34% higher than winter planting. Thousand seed weight was not affected by planting date. The highest water productivity of 0.18 kg oil ha-1.m-3 was obtained in February 1 planting date. Analyisis of  camellia seed oil revealed that linoleic acids (C18: 2) and oleic (C18: 1) had the highest proportion (30.2%) of fatty acids. the proportion of erucic (C22: 1), eicosenoic (C20: 1) and stearic (C18:0) acids which were affedted by  low environmental temperatures in autumn planting dates increased compared to winter planting dates. According to results of this experiment, autumn planting of camellia had higher seed yield with higher oil quality. With delaying planting date, especially in winter, seed developmental stage coinicded with terminal heat that reduced seed yield and seed oil content. However, early winter planing had the highest water productivity.

Development of omega‐3‐rich Camelina sativa seed oil emulsions

Camelina sativa seed is an underutilized oil source rich in omega-3 fatty acids; however, camelina oil is not fully explored for food applications. Its high omega-3 content makes it susceptible to oxidation, which may limit food applications. Therefore, the main objective of this study was to investigate the potential of camelina seed oil to form physically and oxidatively stable emulsions as a...

Pollination of two oil-producing plant species: Camelina (Camelina sativa L. Crantz) and pennycress (Thlaspi arvense L.) double-cropping in Germany

Camelina and pennycress are two annual oil-producing plant species that have recently gained attention as biofuel feedstock crops. Prior to commercial production, information on their breeding and pollination system is essential to ensure sustainable management. We conducted pollination experiments and observed flower visitors in an experimental double-cropping system in southern Germany. We fo...

Over-expression of AtPAP2 in Camelina sativa leads to faster plant growth and higher seed yield

BACKGROUND Lipids extracted from seeds of Camelina sativa have been successfully used as a reliable source of aviation biofuels. This biofuel is environmentally friendly because the drought resistance, frost tolerance and low fertilizer requirement of Camelina sativa allow it to grow on marginal lands. Improving the species growth and seed yield by genetic engineering is therefore a target for ...
