"Agriculture" is an international Open-access, peer-reviewed journal, published semi-annually by Ferhat ABBAS University, Setif1. It is a multidisciplinary journal concerned with all aspects of agricultural world and rural society; a place of scientific information and debate, it is open to any author from several scientific disciplines in relation. It aims to bring together researchers, institutions, practitioners and actors from the rural community. The aim of the journal "Agriculture" is to collect scientific knowledge in the whole field defined in its title. Agriculture refers to all the know-how and activities of conservation and transformation of the natural environment for the cultivation of plants and animals as well as agricultural development policies. The journal welcomes contributions on all aspects of agriculture, in its broadest sense, and publishes articles analyzing the relationship between agronomy and related disciplines: Biology, Hydrology, Ecology, Biotechnology, Climatology, Rural Economics and Soil science. It publishes original research, literature reviews, thematic updates, scientific literature, short papers, comparative articles, and conference proceedings. The main objective of the journal is to communicate scientific progress, disseminate new scientific research, present work such as that leading to quantification and modeling, without neglecting classical studies.







Application of chlorophyll fluorescence for the diagnostic of salt stress of two olive cultivars (Chemlali and Chetoui)

Résumé: The salinity constitutes a major obstacle on the development of olive tree. So the utilization of resistant variety to the salinity is the best solution. Changes caused by salinity on physiological parameters have been measured in two olive (Oleae europaea) cultivars (‘Chemlali’ and ‘Chetoui’) growing in a greenhouse. One year old plants were planted in pot experiment and were irrigated with tap water and saline water (6g/l). The aim of the present study was to assess the salinity tolerance of two olive cultivars (Chemlali and Chetoui) based on the effects of salinity on fluorescence parameters and on the ability of the two cultivars to ovoid transport to leaves of the toxic ions sodium and chloride. We noticed that were a significant decrease on (∆F/F’m) for Chetoui cultivar compared to a non significant decrease for Chemlali. There was a decrease in F0, Fm and Fv/Fm during three weeks after the onset of the salt treatment. The variety Chemlali is characterized by an important accumulation of sodium in roots and an important inhibition of translocation of this element to the aerial part, contrary to variety Chetoui which showed similar sodium concentrations in the root and leaves. Chetoui is considered as moderate sensitive while Chemlali is considered as moderate tolerant.
