This study aimed to investigate the effects of mild salinity stress on some physiological traits and metabolic profiles rice during seedling stage. Three cultivars differing in response, ‘KDML105’ (salt-sensitive, local Thai jasmine rice), ‘IR29’ (salt-sensitive ‘Pokkali’ (salt-tolerant were subjected by flood-irrigated with 40 mM NaCl. Salinity significantly reduces growth biomass sensitive cu...

Senescence is an integral part of the normal developmental cycle of plants and can be traced in cell, tissue and organ level. This work was focused on the efficiency of post-harvest treatment with the free polyamine spermine (Spm) to extend the vase life of cut rose flowers as an anti-senescence compound. Spm treatment was applied at the rates of 0, 1, 2 and 4 mM. Some morphological, biochemica...

Trifolium spp. are native plants in Iran exhibiting good ground cover po-tential. Salinity is a major environmental stress and today, 20% of the world cultivated areas and nearly half of all irrigated lands are affected by salinity. The main aim of this research was to study morphological and physiological adaptations of these native species under different salinity levels for urban landscape u...

Nitric oxide (NO) and 5-aminolevulinic acid (ALA) are both extremely important signalling molecules employed by plants to control many aspects of physiology. In the present study, the role of NO in ALA-induced antioxidant defense in leaves of two sources of Elymus nutans Griseb. (Damxung, DX and Zhengdao, ZD) was investigated. Chilling stress enhanced electrolyte leakage, accumulation of malond...

Oxidative stress caused by glyphosate is a complex chemical and physiological phenomenon develops as result of overproduction accumulation reactive oxygen species (ROS). This study was carried out in vitro at the National Institute Agronomic Research Algeria (INRAA) Setif, to select most susceptible durum wheat (Triticum L.) under oxidative induced herbicide evaluating chlorophyll content degra...

There are many astringent date cultivars at maturity (Full coloration) around the world. These fruits could not be consumed at this stage due to the presence of soluble tannins. Growers have to wait until about 50% of these bunches reach to the rutab stage (ripening) which represents a major source of fruit loss due to abscission, birds attack and pathogens. Furthermore, late-maturing cultivars...

Graphene field-effect transistors are widely used for development of biosensors. However, certain fundamental questions about details their functioning have not been fully understood yet. One these is the presence gate/leakage currents in electrolyte-gated configuration. Here, we report our observations and causes this phenomenon on chemical vapor deposition (CVD)-grown graphene. We observed tr...
