Nature of Floral Stimulus in Perilla as Studied by Grafting : II. Role of endogenous gibberellins and retention of floral stimulus in floral organ

[摘要] In Perilla plants, grafting experiments gave evidence that endogenous gibberellin was not involved directly in the differentiation of floral primordia, but that it plays an important role in the development of floral organ once it has differentiated. Graft of inflorescence, 3-4cm long and in the development stage, onto vegetative receptor stock plant was found to induce flowering on 21.4% of receptor stock plants. This indicates the retention of floral stimulus in floral organ.
