Photosynthetic O(2)-production and photorespiratory O(2)-uptake were measured, using stable isotope techniques, in isolated intact leaf cells of the C(3) plant Xanthium strumarium L., and isolated intact chloroplasts of Spinacia oleracea L (var. Yates 102). Considerable light dependent O(2)-uptake was observed in both systems, a proportion of which could be suppressed by CO(2) (63% suppression ...

BACKGROUND The widespread utilization of antimicrobial compounds has caused emergence of resistant microorganisms in the world. Hence, the research to probe the products with antimicrobial features has led to finding natural habitats and discovering new pharmaceutical products. METHODS In this study, an attempt was made to explore the niche of novel habitat to isolate pyllospheric bacteria fr...

Yabancı otlar domateste (Solanum lycopersicum L.) önemli verim ve kalite kayıplarına sebep olup, hasat işlemlerini de zorlaştırmaktadır. Organik sebze üretiminde yabancı otlarla mücadele yöntemlerinden biride malçlamadır. Bundan dolayı bu çalışmayı 2020 2021 yıllarında Iğdır’da farklı kalınlıktaki malç materyallerinin domates verimi üzerindeki etkileri belirlemek amacıyla yürütülmüştür. Çalışma...

Flowering is induced in Xanthium strumarium by a single dark period exceeding about 8.3 hours in length (the critical night). To study the mechanism which measures this dark period, plants were placed in growth chambers for about 2 days under constant light and temperature, given a phasing dark period terminated by an intervening light period (1 min to several hrs in duration), and finally a te...
