Abstract
Investigations of the effect of H-140/CCC/ on growth and flowering of greenhouse azaleas have shown the possibility to make use of this growth retardant in practice.
Six weeks after the last pinching one-year-old plants of cvs.
Mrs John Haerens and Vervaeneana Salmonea were planted into 12 cm pots.
Peat substrate was mixed earlier with H-140 in amount 2 g or 4 g per 1 litre.
After the next 6 weeks some plants were treated with water solution of H-140 in concentration 1 % or 2 % – 100 ml per pot.
The best results were obtained when the substrate contained the lower amount of retardant and plants were also treated with CCC as a drench.
The higher amount of H-140 caused the delay of flowering in both cultivars.
Furthermore, it reduced the diameter of flowers cv.
Mrs John Haerens and even caused dropping of buds cv.
Vervaeneana Salmonea.
