Key words: Oil quality, fatty acid composition, phenolic compounds, pigment content, mountain, Kesra.

Abstract

Kesra is a mountainous region characterized by an important olive biodiversity with high oil quality but little is known about this olive germplasm. The aim of this work is to analyze the oil quality of the most predominant varieties ‘Chétoui’, ‘El hor’ ‘Sradki’ and ‘Ouesleti’ cultivated in this region.

Key words: Freshwater fish species, length-weigh relationship, condition, Taï National Park, West Africa.

Abstract

This study describes the length-weight relationships (LWR) and condition factors of twenty-four fish species from eleven families found in rivers of Taï National Park. A total of 1545 specimens were caught by using various mesh size of gill nets between January 2012 and September 2013.

Key words: Compost, continuous cropping, improved fallows, natural fallow, soil fertility.

Abstract

Improved fallows have been promoted in Uganda as alternative soil fertility management options to enhance sustainable land management. The major contribution of improved is through biological nitrogen fixation and high quality soil organic matter.

Key words: Polygonaceae, Rumex, fruit morphology, Iran.

Abstract

The genus Rumex with about 23 species is one of the most important species of the family Polygonaceae in Iran. In order to reveal the relationship of Rumex species we used fruit morphological characters including valve and achene features. Valves size and shape are variable among species.

Key words: Dacryodes edulis, psyllids, pest management, Cameroon.

Abstract

Dacryodes edulis (G. Don) H. J. Lam (Burseraceae) is an oleiferous plant originated from Central Africa. This plant is cultivated for her fruits rich in proteins and lipids. The tree suffered serious damages caused by insect pests. In Cameroon, four psyllids species feed on D. edulis: Pseudophacopteron tamessei, P. pusillum, P. eastopi and P. serrifer.
