PRELIMINARY STUDIES ON COLD HARDINESS OF SOUTHERN MAGNOLIA

Cold Hardiness of Woody Plants

stresses caused by their freezing and thawing. A key difference between a hardy plant and a non-hardy plant is believed to be where the ice forms in freezing: inside the living cells or outside of them. If ice forms inside of cells, it is almost always fatal to them, and this is probably the principal cause of frost kill in non-hardy plants. Normally hardy tissue may be killed by moderate tempe...

Preliminary studies on reproductive activities of local Abadeh does, Fars province, southern Iran

No published information are available on the reproductive indices of local Abadeh does reared innorthern Fars province, southern Iran. This study was conducted to determine the duration of the breedingseason, and the length and duration of the oestrous cycle. Twenty single parity 2-year-old does from Abadeh(weighing 19–26 kg) were purchased and transferred to the School of Veterinary Medicine ...

Water Permeability and Cold Hardiness of Cortex Cells in Cornus stolonifera Michx.-A Preliminary Report.

The relationship of freezing resistance to water permeability of cortex cells was studied in stems of red osier dogwood (Cornus stolonifera Michx.). Permeability was estimated by determining the diffusion flux of tritiated water from cortex slices previously equilibrated in tritiated water. Energy of activation and diffusion time comparisons of tritiated water flux from living cortex slices and...

Measuring Cold Hardiness in Woody Plants

Understanding plant cold hardiness: an opinion.

How plants adapt to freezing temperatures and acclimate to survive the formation of ice within their tissues has been a subject of study for botanists and plant scientists since the latter part of the 19th century. In recent years, there has been an explosion of information on this topic and molecular biology has provided new and exciting opportunities to better understand the genes involved in...
