ABSTRACT: At the Agricultural Research Center - Apopka we have been studying the breeding potential within the genus Dieffenbachia. One goal of this program is the development of new and better varieties of Dieffenbachia for commercial production in Florida. Another important objective is to study the reproductive mechanisms of fJieffenbachia and learn more of their biology and how it relates to all tropical plants in general and other aroids in particular. Such studies include research into factors affecting plant growth, flowering, pollen and seed production and storage and inheritance of various plant characteristics (leaf and petiole variegation, growth habit, etc.).

ABSTRACT: Although the flower structure and pollination method are known (1), difficulty in obtaining seed from selected crosses is a major reason that few hybrid Dieffenbachia exist. However, recent studies at the Agricultural Research Center - Apopka concerned with environmental factors affecting seed production in Dieffenbachia have led to greatly improved seed yields and made hybrid production easier.

ABSTRACT: Dieffenbachia breeding has been hindered by sporadic flowering and the small number of inflorexcences per plant. In attempting to surmount this problem we initiated experments to see if it would be possible to control flowering using the plant hormone gibberellic acid (GA3,. The study was conducted on full-sized plants of Dieffenbachia maculata 'Perfection' grown in 6-inch pots. Treated plants were sprayed on their upper and lower leaf surfaces until runoff with either 250, 500 or 1000 parts per million GA3 while control plants were sprayed with water only. Ten plants were tested at each of the four GA3 levels and plants were maintained in a greenhouse held at 65-90oF temperature range. GA 3 was tested because it had previously been shown to induce flowering in many crops as well as some aroids (1,2,3,4).
