Vegetative Growth and Flowering of Russelia equisetiformis Affected by Different Growth Regulators

Abstract

This study examined the effects of different growth regulators, such as Cycocel (CCC) at 1000 and 1500 ppm, Ethephon at 300 and 450 ppm, and Daminozide at 2000 and 4000 ppm on the growth and flowering of Russelia equisetiformis as a potted plant. The results showed that CCC treatments significantly reduced plant height and root length, while Daminozide treatments increased them. CCC
treatments also promoted the highest number of main and secondary shoots, whereas Ethephon treatments resulted in the lowest flower and root numbers. Flower production showed no significant difference between CCC and Daminozide treatments, but was lowest for Ethephon treatments. Fresh and dry weights were highest for Daminozide treatments and lowest for Ethephon and the control treatment. The study recommends using specific plant growth regulators to enhance the growth of Russelia equisetiformis in pots.
