Hardiness of Plants

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

Preliminary Results in Measuring the Hardiness of Plants.

The injury of plants occasioned by winter conditions has been a subject of great interest and importance to plant breeders and agriculturists. The development of hardy strains has been, and is, one of the principal means of comiibating losses caused by injury from cold, although cultural methods, as well, lhave been adapted to help the plant survive the rigors of its climatic environiment. Reco...

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...
