Screening Malus Seedlings for Cold Hardiness

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...

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...

Factors Affecting Cold Hardiness in Grapevines

What Determines a Plant's Cold Hardiness?

near future because both our understanding of plant physiology and our ability to manipulate plant cold hardiness have improved. Without question, resistance to low temperatures is a major factor determining the geographic distribution of plant species. Socalled chillmg-sensitive plants, such as the tropical banana and the semitropical avocado, can be severely injured or even killed by long-ter...
