Growth behavior of green and albino plants ofEpiscia cupreata “Pink brocade” in vitro

Summary Green and albino plants were regenerated from green and white tissues, respectively, of a chimeric,Episcia cupreata “Pink Brocade.” The green plants grew much faster in vitro than the albinos. The slower growth of albinos apparently was not the result of carbohydrate deficiency, as it could not be corrected by increased sucrose. Growth of the albinos was also not improved by supplementation with various amino acids, growth hormones, or Δ-aminolevulinic acid.
