(1) It was found that the anodal isoperoxidase pattern of parrot mutant tepals differs distinctly from tepals of their mother cultivars, but no differences were observed in cathodal isoperoxidases.
(2) Fibrillar chromoplasts in tepals of Lilium croceum are able to synthesize starch in vitro, not, however, from glucose but from glucose-1-phosphate.
(3) Comparison of surface growth patterns and differentiation events in the gynoecium to those previously described in the tepal and another demonstrates the triphasic nature of growth in the whole lily flower.
(4) The isoperoxidase spectrums of 2 single tulip cultivars and their parrot mutants were analyzed by disc electrophoresis in leaves and tepals i.e.
