PRUNING EFFECTS ON COLD HARDINESS OF TWO WOODY ORNAMENTAL PLANT TAXA

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...

Salt tolerance & protoplasmic salt hardiness of various woody & herbaceous ornamental plants.

The interest in salt tolerance of plants, especially those of economic importance, is increasing as more saline lands are brought under cultivation, and as saline irrigation waters add to the salinity of cultivated soils. Research relating to the survival and growth of plants growing on soils containing excessive soluble salts has left many problems unsolved. The task of obtaining and selecting...
