摘要

Leaves of young tea plant are often severely injured by cold wind. This injury occurs suddenly and their symptoms are just the same as those of drought injury. It was thought that one of the direct causes of this injury was sudden decrease in water content of tea leaves. At tea gardens transplanted shortly before, the root conditions were thought to have some relations to the occurrence of this injury. The growth of tea varieties varies according to air temperature, and early varieties commence their growth earlier and more easily dehardened at lower temperature than late varieties.
