—It is important to identify rapid and accurate methods for assessing hardwood seedling quality and physiological status. Evaluation of electrolyte leakage (EL) from plant tissues is promising for this purpose. It has successfully predicted the physiological status of conifer seedlings and has been used experimentally on European hardwood species. Three species of hardwoods, northern red oak (Q...

screening methods that are effective in the early stage of growth will potentially provide the largest quantity of breeding material. although various screening methods under greenhouse have been proposed, potential effective approaches must be described a good correlation with results under field conditions. this study was aimed to assess the correlations between traits obtained from four salt...

BACKGROUND The purpose of this study was to evaluate the prevalence of cold sensitivity in patients with hand- and wrist-related diagnoses. METHODS We included English-speaking adults who were more than 1 month following hand injury or onset of symptoms. Patients were asked if exposure to cold air or water provoked cold-related symptoms and to rank symptom severity (scale 0-10). Statistical a...

Rice is sensitive to cold stress, and cold tolerance in rice is a complex trait. In the present study, DNA methylation alterations induced by cold stress were examined in two contrasting rice genotypes, Li-Jiang-Xin-Tuan-Hei-Gu (LTH) and IR64, by methylation-sensitive amplified polymorphism analysis. At the seedling stage, a remarkable increase in DNA methylation under cold stress was detected ...

Patients who acquired an upper extremity nerve injury often complain about cold intolerance, reduced sensitivity and decreased task performance. This study tried to quantify these complaints and look in more detail at the thermal reaction to local cold exposure of the affected limb. We found that 36% of 107 subjects could be classified as cold intolerant. Eight of the cold intolerant subjects i...

wild almond (amygdalus scoparia) is one of the most important species that provides a variety of ecological functions in the zagros forest ecosystem. in this study, we investigated the effects of some seed treatments on the survival and growth of amygdalus scoparia after seed planting at different aspects and elevations under natural conditions. the seed pretreatments consisted in soaking them ...
