Polar ocean stratification in a cold climate [PDF]
Nature, 2004 The low-latitude ocean is strongly stratified by the warmth of its surface water. As a result, the great volume of the deep ocean has easiest access to the atmosphere through the polar surface ocean. In the modern polar ocean during the winter, the vertical distribution of temperature promotes overturning, with colder water over warmer, while the ...

Cold Stratification of Pacific Madrone Seeds [PDF]
Native Plants Journal, 2004 Cold moist stratification for 40 d resulted in excellent (≥ 87%) germination for 11 seed lots of Pacific madrone (Arbutus menziesii Pursh. [Ericaceae]) from California, Oregon, and Washington. Without stratification, germination was with latitude but not with elevation or mean winter temperature.

Effect of duration of stratification on growth and chemical properties of Ash (Fraxinus excelsior L.) [PDF]
تحقیقات جنگل و صنوبر ایران, 2017 Cold stratification is widely used to break dormancy of ash (Fraxinus excelsior L.) seeds. In this study, two groups of seedlings produced by two treatments of ash seeds, one and two-years cold stratification of seeds were investigated with three ...

Cold Stratification Improves Germination of Katsura Tree [PDF]
HortScience, 1997 Katsura tree ( Cercidiphyllum japonicum Sieb. & Zucc.), an ornamental tree native to Japan and China, is valued for its broad pyramidal form and apricot-yellow fall leaf color. Another species, Cercidiphyllum magnificum (Nakai) Nakai, exists, but is

Seed size and cold stratification affect Acer negundo and Acer ginnala seeds germination [PDF]
, 2020 The aim of this work is to determine how the germination of seeds of the invasive tree Acer negundo depends on the period of cold stratification under the snow and the duration of stratification in the air on the branches of the trees.

Optimizing Seed Germination and Seedling Growth in Different Kiwifruit Genotypes
Horticulturae, 2021 The presence of dormant embryos in seeds and nonuniformity in seedling growth are the main limiting factors for kiwifruit propagation. Studies on the germination of hybrid genotypes are limited, especially at different ploidy levels.

New insight into stratification of anaerobic methanotrophs in cold seep sediments [PDF]
FEMS Microbiology Ecology, 2011 Methane seepages typically harbor communities of anaerobic methane oxidizers (ANME); however, knowledge about fine-scale vertical variation of ANME in response to geochemical gradients is limited. We investigated microbial communities in sediments below a white microbial mat in the G11 pockmark at Nyegga by 16S rRNA gene tag pyrosequencing and real ...
