Wakes in stratified flow past a hot or cold two-dimensional body [PDF]

open access: yes, 1976
This paper considers the general problem of laminar, steady, horizontal, Oseen flow at large distances upstream and downstream of a two-dimensional body which is represented as a line source of horizontal or vertical momentum, or as a line heat source or

Effect of provenance and chemical treatments on the germination characteristics in immature seed of linden [PDF]

open access: yesمجله جنگل ایران, 2018
One of the problems of propagation of lindens (Tilia spp.) is low seed germination. In this research, different treatments for stimulating the germination in immature seeds of Tilia rubra subsp. caucasica form angulata collected from middle altitude (500

Polypeptide Alteration During The Cold Stratification In Mazzard Seed

open access: yesErwerbs-Obstbau, 2017
Many seeds of woody plants require low temperature for germination and that’s called seed dormancy has been investigated for relations of proteins by several researchers. We determined polypeptide profiles of cold-stratified Mazzard seeds. Seeds were studied in five different periods: seeds in dormancy (none stratified), 30, 60, 90 and 120 days cold ...

The Role of Wet Processes in Extratropical Thermal Stratification During the Glacial Period

open access: yesGeophysical Research Letters, 2023
In this study, we differentiate wet processes from dry processes in shaping the extratropical thermal stratification during the Last Glacial Maximum. Our findings indicate that even during the dry glacial period the influence of wet processes on thermal ...

INFLUENCE OF OVERCOMING DORMANCY METHODS ON MAGNOLIA X SOULANGEANA SOUL. BOD. SEEDS GERMINATION

open access: yesAgricultura, 2010
The goal of the experiments carried out was to analyse the influence of different types of preseeding treatment on the germination and dormancy breaking of Magnolia x soulangeana seeds. Seven types of preseeding treatment were used to break seed dormancy

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

open access: yesAFRICAN JOURNAL OF BIOTECHNOLOGY, 2011
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

Resonantly damped oscillations of longitudinally stratified coronal loops [PDF]

open access: yes, 2006
Soon after coronal loop oscillations were observed by TRACE spacecraft for the first time in 1999, various theoretical models have been put forward to explain the rapid damping of the oscillations of these intriguing objects.

Gene expression patterns in wheat coleorhiza under cold- and biological stratification

open access: yesMicrobiological Research, 2014
This study assessed germination of wheat seeds under cold and biological stratification and determined the expression level of gibberellins (GA) and abscisic acid (ABA) genes in coleorhiza.
