Β-Sitosterol Ameliorates The Chemical Constituents Of Sunflower (Helianthus Annuus L.) Plants, Grown Under Saline Condition
Journal Title: IOSR Journal of Pharmacy and Biological Sciences (IOSR-JPBS) - Year 2016, Vol 11, Issue 3
Abstract
The present experiment was carried out in fancied area at El-Mansoura University, Dakahlia Governorate during the growth period, from May to September (2013) to study the effect of different salinity levels (10, 20 and 30%sea water) and beta-sitosterol (10-5 , 10-7 and 10-9 molar) on some chemical aspect of sunflower plants (Helianthus annus L.). The results indicated that salinity caused a reduction in chlorophyll a, b, a+b, a/b and Carotenoids as well as total pigments, carbohydrates contents with significant increasing sea water concentration during two stages of growth, 45 and 85 days from planting. Also a marked reduction in unsaturated fatty acids content accompanied with a marked increase in saturated fatty acids as compared to untreated control plants especially myristic acid. Increasing β-sitosterol concentration significantly increased chlorophyll a, b, a+b and Carotenoids as well as total pigments content of sunflower leave which reflected on carbohydrates fractions during both stages except chlorophyll a/b which had no significant effect during 45 and 85 days from the planting. Marked increases were observed in unsaturated fatty acid contents, as compared with the control plants. It can be noticed that the plants treated with β-sitosterol concentration with(10-5 molar) attained the highest chlorophyll a, b, a+b, carotenoids and total pigments also, carbohydrates fractions as compared with the other treatments during both stages.
