Herbaceous Plant Cover Establishment In A Barren Materials Quarry, Nikolaos Arambatzis, Kitikidou Kyriaki

Turkish Journal of Botany

The ability to establish cover using grass and legume species without any soil preparation was studied in a barren materials quarry. The biodiversity indexes (Simpson) during the growing season as well as the vegetation cover and composition were measured. The results showed that the established species had a satisfactory cover (up to 87.5%). This means that we can achieve significant soil rehabilitation after mining using herbaceous plant cover and reduce the cost of rehabilitation by cutting the expenses of soil preparation.

The Effects Of Ultraviolet Radiation On Some Antioxidant Compounds And Enzymes In Capsicum Annuum L., Kobra Mahdavian, M. Ghorbanli, Khosrow Manochehri Kalantari

Turkish Journal of Botany

Plants have evolved mechanisms to avoid and repair UV radiation damage; it is not surprising that photomorphogenic responses to UV-B and UV-C are often assumed to be adaptations to harmful radiation. Free radicals generated by UV are likely to be involved in the induction of antioxidant defence system. In this study plants were grown for 5 weeks in controlled conditions. Plants were grown in vermiculite medium before applying the UV treatments, and irrigated daily by Hoagland solution for 5 weeks. After 5 weeks, plants were exposed to UV-A (320-390 nm), UV-B (312 nm), and UV-C (254 nm) irradiation with a …

Biogeography Of South-West Asian Bryophytes – With Special Emphasis On The Tropical Element, Harald Kürschner Jan 2008

Biogeography Of South-West Asian Bryophytes – With Special Emphasis On The Tropical Element, Harald Kürschner

Turkish Journal of Botany

The recent bryophyte flora of South-West Asia is heterogeneous and consists of 6 floral elements [(Sub)cosmopolitan taxa, northern taxa, xerotherm-Pangaean taxa, circum-Tethyan taxa, tropical taxa, and endemics of various origins] that are derived from the different Pangaean ancestral floral stocks. Analysis of the flora and vegetation indicates that there is a very strong tropical - and especially palaeotropical and Afromontane - influence in the bryophyte flora of the area. Altogether, more than 95 taxa, or nearly 10% of South-West Asia´s total known bryoflora, are of xero-tropical origin. They concentrate mainly in the escarpment mountains of the Arabian Peninsula and Socotra …
