Switchgrass Population and Cold–Moist Stratification Mediate Germination

Crop Science, 2015
ABSTRACTSwitchgrass (Panicum virgatum L.) breeding and selection have enhanced the agronomic qualities of this species as a crop for forage and bioenergy applications. Previous work has characterized variation in phenotypic traits (e.g., survival, biomass yield, and cell wall carbohydrates) among wild and cultivated populations.

Fluent analysis of a ROSA cold leg stratification test

Nuclear Engineering and Design, 2010
One of the OECD ROSA project tests, investigating temperature stratification in the cold legs and the downcomer during ECCS water injection under single-phase natural circulation conditions was analysed with the FLUENT code. The guidance given in the “Best Practice Guidelines for the Use of CFD in Nuclear Reactor Safety Applications” of the OECD GAMA ...

Cold Stratification Requirements for Germination ofAlliaria petiolata

Invasive Plant Science and Management, 2008
Abstract Garlic mustard is among the most important invasive weeds of North American eastern deciduous forests. Investigations of the mechanisms that enable its success as an invader require a simple method to propagate this weed in the laboratory and the greenhouse; we develop such a method in this study.

Cold Soaking—A Short-Cut Substitute for Stratification?

Journal of Forestry, 1950
Abstract Exploratory tests indicate that cold-water soaking of seeds of some Lake States conifers for one to two weeks may be as effective in overcoming internal dormancy as cold stratification for one to three months.

EFFECTS OF COLD STRATIFICATION AND HORMONES ON SEED GERMINATION OF SARRACENIA ALATA

Texas Journal of Science, 2019
Abstract Seed germination requirements for S. alata were investigated using cold stratification and phytohormones. Treatments included no stratification (control), two week, three week, four week, five week, and six week cold stratification. Hormone treatments included no stratification with cytokinin, no stratification with gibberellins, no ...

Effects of Stratification on Surface Frontogenesis: Warm and Cold Fronts

Journal of the Atmospheric Sciences, 1984
Abstract The role of the ambient stratification in semigeostrophic surface frontogenesis is examined. Model fronts forming in regions of large static stability 1) are weaker, 2) are tilted more toward the horizontal, and 3) propagate more slowly toward the warm air than fronts forming in regions of small static stability. These results are discussed in

Effects of temperature, salinity and cold stratification on seed germination in halophytes

Nordic Journal of Botany, 2012
Salt tolerance of halophytes corresponds with the habitat requirement of the species. It is an important factor during the germination phase and it can determine successful establishment. This paper presents the effects of alternating temperature–light regimes (4/8°C, 10/20°C, 20/32°C; 12 h dark: 12 h light) and different salinity ...

Phenomenon of Mechanoinduced Atomic Stratification in Alloys under Cold Plastic Strain

Russian Physics Journal, 2001
Low-temperature (24°C) redistribution of nickel in K12N30 and K12N40 stable austenitic steels under strong (e > 9) cold shear strain at a pressure of 8 GPa is investigated. The strain-induced atomic stratification of FCC alloys is identified from the enhanced alloy magnetization and the occurrence of ferromagnetic microregions with vastly higher Curie ...

Cold stratification, but not stratification in salinity, enhances seedling growth of wheat under salt treatment

2013
Cold stratification was reported to release seed dormancy and enhance plant tolerance to salt stress. Experiments were conducted to test the hypothesis that cold stratification and cold stratification in salinity could enhance seedling growth of wheat under salt treatment. The results clearly demonstrated that cold stratification significantly improved
