Dr. Olga Rozentsvet, Lipid Content Variation in Plantago media Leaves in Response to Light Conditions(2016)SDRP Journal of Earth Sciences & Environmental Studies 1(20)
The aim of the present work was to study the variation of lipid and fatty acids composition as well as morphometric characteristics of Plantago media leaves from the different light conditions in northeastern Russia. The leaves of the plants grown under lower light had lower leaf mass/area ratio but larger areas of lamina. They accumulated lower levels of lipid peroxide products. It was found that as the duration of sunshine increased, the content of total lipids increased (r = 0.78), but an increase in temperature resulted in a decrease of their content (r = - 0.70), especially for plants in high-sunshine habitats. Concentration of GL in leaves of shaded plants increased with increasing precipitation but decreased with increasing temperature and the duration of sunshine. Amount of saturation FA increased with increasing temperature and the duration of sunshine. Precipitation contributed to the accumulation of unsaturation FA. Thus, the content of lipids in the leaves depended on weather and microclimate conditions.
