Drought stress and its intensity, the factor of strategies selection for drought tolerance in Haloxylon aphyllum
Osmotic parameters of Haloxylon aphyllum were studied after inducing dryness. Water relations parameters with improving resistance to dryness of this species through inducing severe dryness and clarification of physiologic mechanisms of this plant in response to a low water and dryness were among the objectives of this study. For this purpose, the method of pressure chamber was employed. By this method, the...

Chemical profiles as chemotaxonomic tools for Loranthaceae in Nigeria
The Loranthaceae species are widespread throughout most regions of the world, and are used for various medicinal and ethnopharmacological purposes. However, the species vary in their pharmacological activity, sometimes in correlation with the species from same ecological region or host plant, due to variation in the chemical profiles. This has led to great emphasis on caution in identification and collection for use....

Effects of crude extracts on some selected physiological parameters of French beans (Phaseolus vulgaris) infected with rust (Uromyces appendiculatus)
Rust (Uromyces appendiculatus) is a major foliar disease that reduces yield and pod quality in beans. The field trial of French beans was established at Jomo Kenyatta University of Agriculture and Technology (JKUAT). Single plant extracts and combinations of Boscia angustifolia, Zanthoxylum chalybeum and Melea volkensii were used to evaluate their effect on U. appendiculatus in the field. During the growing period,...

Fatty acid composition of the seed oil of Chrysophyllum albidum (G.Don)
The fatty acid composition of seed oil of Chrysophyllum albidum was determined by gas chromatography-mass spectroscopy (GC-MS). The seed oil contained much important fatty acids with linoleic (26.21%) and palmitic (14.41%) acids being the most abundant unsaturated and saturated fatty acids, respectively. The total unsaturation for the oil was 67.61%. These results confirm that the oil of C. albidum is of industrial...

Chemical characterization and antimicrobial activity of essential oils and Croton’s varieties modulator in the Brazilian’s Northeast semiarid
This study aimed to analyze the chemical composition and evaluate the antibacterial activity of essential oils and modulator of Croton heliotropiifolius Kunth and Croton blanchetianus Baill. The oils were obtained with distilled water and their components identified with GC/MS. Eucalyptol (16.9%), β-caryophyllene (15.9%) and germacrene-D (14.5%) for C. heliotropiifolius and cedrol (28.4%), eucalyptol (17, 4%) and...
