IMPROVING STEM LENGTH AND FLOWER QUALITY OF LEUCOSPERMUM WITH GROWTH REGULATORS

Hybrids of Leucospermum conocarpodendron x L. cordifolium produce flowering stems which are too short to market.
Treating plants with gibberellic acid stimulates shoot growth.
Both internode length and number of internodes are increased.

Flower quality of Leucospermum cordifolium x L. line are cv.
Red Sunset was improved by benzyladenine treatment.
Spraying plants during the latter half of March caused an increase in the number of florets per inflorescence and the dry weight of the inflorescence.
