title: Seasonal Growth Periodicity of Tissue Explants from Woody Perennial Plants in vitro.
abstract: Secondary phloem explants removed to standard aseptic culture in the spring proliferate most extensively. Explants taken successively through the growing season proliferate less. The decreasomg growth trend reverses some months before bud break, and the increasing growth in winter is not dependent on the breaking of dormancy in the terminal buds.
