State of the lipid and fatty acid composition in chloroplasts of Nicotiana tabacum under the influence of an increased CO2 partial pressure of 700 p.p.m.

چکیده
We analysed chloroplast lipids of Nicotiana tabacum var. John William's Broadleaf, cultivated under an increased PCO(2) of 700 p.p.m. Glycolipids and phospholipids remain constant under these conditions, whereas the carotenoid content undergoes a quantitative change. The saturation degree of fatty acids increases due to an increase in palmitic acid and decreases in hexadecatrienoic acid and linolenic acid.

Salinity is a complex phenomenon that involves not just an osmotic effect, but also toxic ion effects and nutritional imbalance. In order to evaluate the effects of severity and duration of sodium chloride stress on some biochemical and photosynthesis parameters of tobacco a factorial experiment was conducted using a randomized completely block design with three replication with using a hydropo...
متن کاملEffect of cryopreservation on lipid composition and antioxidant enzyme activity of seabass (Lates calcarifer) sperm
Cryopreservation of seabass (Lates calcarifer) semen is an approach to increase the quantity and quality of seabass fry in aquaculture. However, cold shock can induce sperm injury leading to structural damage of the plasma membrane and loss of motility. Thus, the effect of cryopreservation on fatty acid composition and antioxidant enzyme activities of seabass sperm was determined. In cryopreser...

The effect of salting by different salt composition on fatty acid profile studied in hot smoked Black and Caspian Sea sprat, Clupeonella cultriventris. After initial prepare activities, samples were exposed to brining process within two salt concentrations including of 100 % NaCl (treatment 1 or T1) and 75 % NaCl- 25 % KCl (treatment 2 or T2) under 15% brine solution for 3 hrs. The smoking proc...
