Native trout species, such as the redband trout (Oncorhynchus mykiss), occupy thermally harsh stream habitats in hot, arid rangeland basins of the western United States. Declines in the distribution and abundance of these species has generated interest in understanding how these cold water species survive in these systems, as well as in identifying opportunities to restore these species to thei...

Most tree species in the temperate climatic zone (including Douglas fir) disperse seeds autumn. Some of them must be exposed to cold (0–10 °C) and moist conditions (cold stratification) overcome dormancy trigger germination. In Northern Hemisphere, winter warm spells occur more frequently last longer than recent decades from eastern Canada Europe. Our main research objective was investigate inf...

Abstract Juniperus oxycedrus L. and Pistacia lentiscus are two taxa with a rigid or enough structure caused by solid pericarp resulting in strong inhibition of the germination. The objective this work was to test effectiveness certain pre-germinative treatments on germination rate seeds aim restoring perturbed ecosystems. In context 180 from each 2 examined species were tested laboratory (the n...

Propagation of hawthorns (Crataegusspp.) is difficult, and vegetative methods are not responsive in a sufficient manner. So, seed propagation prevalently used to propagate hawthorns. However, hard endocarp embryo dormancy restrict the germination To overcome these restrictions, many treatments have been tested researches. Some them were magnificent others ineffective. It has resolved that warm ...

aim and background: capparisspinosa l. is considered as one of the most significant plant species in the capparaceae. this plant is one of the most important medicinal plants and has a great ability to stabilize sand dune. seeds of this plant have germination problems. the aim of this research is to determine germination percentage of capparisspinosa according to different duration of chilling ...

IN TRADITIONAL CHINESE MEDICINE (TCM), PATIENTS WITH RHEUMATOID ARTHRITIS (RA) CAN BE CLASSIFIED INTO TWO MAIN PATTERNS: cold-pattern and heat-pattern. This paper identified the network-based gene expression biomarkers for both cold- and heat-patterns of RA. Gene expression profilings of CD4+ T cells from cold-pattern RA patients, heat-pattern RA patients, and healthy volunteers were obtained u...

This research was carried out to determine the effects of germination temperature and 12 dormancy breaking applications on seeds gum tragacanth (Astragalus gummifer Labill.) bush. The in Field Crops Department laboratory, I?d?r University Faculty Agriculture, 2019. Gum were germinated for 28 days dark at constant temperatures 10, 15, 20, 25 °C variable 20/10 °C, 20/15 25/10 25/15 °C. As a resul...

-Thermal stratification occurred in pools of three rivers in northern California when inflow of cold water was sufficiently great or currents were sufficiently weak to prevent thorough mixing of water of contrasting temperatures. Surface water temperatures in such pools were commonly 3-9°C higher than those at the bottom. Cold water entered pools from tributaries, intergravel flow through river...

The timing of seed germination significantly affects the fitness and life cycle plants. Torilis scabra is a perennial medicinal herb occurring in mixed forests but increasing use modification forestlands recent decades has led to degeneration its natural habitat. Nonetheless, requirements for T. remain unclear. present study focused on identifying conditions necessary break dormancy describing ...
