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 ...

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 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 ...

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

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 ...

Safety oriented analysis of cold helium–air mixture formation and stratification

Cryogenics, 2006
Abstract Cryogenic installations of superconducting accelerators contain significant amount of high density helium, mostly filling the cryostats and headers located in underground tunnels and caverns. In the case of emergency relief of the helium, oxygen deficiency hazard arises.
