Lipids of air-dried leaves of the hemi-halophyte plant Limonium gmelinii (Willd.) Kuntze (Plumbaginaceae) growing on the dry bed of the Aral Sea were studied. The leaves contained neutral lipids (NL, 0.84% of the mass), glycolipids (GL, 1.78), and phospholipids (PhL, 0.74). The compositions of the lipophilic constituents of the NL and hydrocarbons were determined. Fatty acids of NL were dominated by 18:2n6 (53.45%); of GL and PhL, 16:0 (40.14 and 53.98%, respectively). The lipophilic constituents exhibited weak antifungal and high growth-stimulating and stress-protective activity under salt stress conditions. [ABSTRACT FROM AUTHOR]

The constituent and fatty-acid compositions of neutral lipids (NL), glyco-, and phospholipids and the squalene contents in seeds and the aerial part of Amaranthus retroflexus were studied for the first time. Elaidic acid was observed in all lipid groups. The squalene content was 4.3% of the NL mass in seeds and 3.15% in the aerial part. Preliminary wetting of wheat and cucumber seeds in unsaponified substances, fatty acids, and their methyl esters obtained from A. retroflexus seeds at concentrations 0.001 and 0.0001% was found to reduce the inhibiting action of salt stress. Neutral lipids did not exhibit a protective effect. [ABSTRACT FROM AUTHOR]

Seed characteristics and the lipid and fatty-acid compositions were determined for the new cotton varieties ASh-25, Omad, 9771-I, Termez-43, and Bukhara-6. [ABSTRACT FROM AUTHOR]
