Cold injury and hardiness.

The article focuses on research on plant hardiness in context of cold injuries. Topics discussed include experiments conducted by British horticulturists by experimenting with news selections, the Royal Horticultural Society's Hardiness Ratings Scale which is defined by a direct relationship with temperature and the process of acclimatization in which plants gothrough for dormancy as temperature decline. Also mentioned is the importance of genes related to carbohydrate biosynthesis.
