Abstract Background As a biennial plant, Secale cereale L is usually harvested in the autumn northern part of China where temperature difference between day and night great disparity Through pot experiment, seedlings were cut to 2, 6 10 cm stubble height, simulated freeze-thaw (FT) stress (10/− 5 °C) was carried out after days regrowth. The physiological effects FT with different height reveale...

Osmotic and oxidative stress responses to iso-osmotic (-0.4 Mpa) NaCl, PEG-6000 and mannitol stress were studied in 15-day old plants of three potato cultivars viz. ‘Kufri Kufri Bahar’ ‘Jyoti’ and ‘Chandramukhi’. After 2-weeks of treatment, plants were analyzed for biochemical and physiological determinants of stress. Relative water content (RWC) and membrane damage rate (MDR) were significantl...

OBJECTIVE Hypothyroidism is cited as an uncommon cause of ventilator-dependent respiratory failure. The objective of this study was to determine the incidence of hypothyroidism in patients with respiratory failure, receiving prolonged mechanical ventilation (PMV) with failure to wean, referred to a regional weaning center (RWC) for weaning. SETTING RWC. DESIGN Retrospective. METHODS Medic...

The broad-band ultrasonic spectroscopy technique allows the determination of changes in the relative water content (RWC) of leaves with contrasting structural features. Specifically, the standardized frequency associated with the maximum transmittance (f/f(o)) is strongly related to the RWC. This relationship is characterized by the existence of two phases separated by an inflexion point (assoc...

Hydrogen gas (H2) and carbon monoxide (CO) are involved in plant growth and developmental processes and may induce plant tolerance to several stresses. However, the independent roles and interaction effect of H2 and CO in adventitious root development under drought conditions have still not received the needed research attention. We hypothesize that there exists crosstalk between H2 and CO duri...

With increasing frequency and intensity of dry spells in the cocoa production zones West Africa, strategies for mitigating impact water stress on seedling survival are urgently required. We investigated effects applied potassium biomass accumulation, physiological processes varieties subjected to pot experiments a gauzehouse facility. Four levels (0, 1, 2, or 3 g/plant as muriate potash) were u...

A pot experiment was conducted to determine the response of two recent forage sorghum cultivars (JS-2002 and Chakwal Sorghum) and an old one (JS-263) to three levels of soil moisture (30%, 50% and 70% field capacity). Several traits were assessed addressing plant morphology, functional growth, leaf water status, biomass yield and water use efficiency (WUE). Soil moisture variation greatly affec...

Research Project of Optical Information Technology at ETL under RWC program is given in detail. In this program, firstly, so called CAD (computer-aided design) system for optical devices will be established for the purpose of acceleration on the development of semiconductor optical devices. Devices developed under the CAD system will be implemented into new types of optical information systems ...
