Cococarpus lancifolius Engl. grows wild in Djibouti, Somalia and East Africa, and South Asia. The species was introduced into Kuwait, where it is exposed to several stresses: oil pollution, salinity, high temperature and harsh climatic conditions. These conditions are prevalent in its semi-arid environment. In this study, the impact of salinity (2, 6 and 10%), temperature (20, 30 and 40 °C), polyethylene glycol (10, 30 and 60%) and drought has been investigated on C. lancifolius. Proline (Pro) accumulation (5.5 ± 0.03 µg/g dry weight; p=0.05-0.005), protein (16.47 ± 0.052 mg/g; p=0.001), free amino acids (10.92 ± 0.082 mg/g; p=0.006) and lipids (116.05 ± 2.17 µg/g; p=0.05) were measured in plants irrigated with 60% polyethylene glycol (PEG) for 6 days.... |
