Growth, flowering and gas exchange of Rellia brittoniana treated with different concentrations and application frequencies of daminozide

Ruellia brittoniana is a fast growth plant with a strong tendency of vegetative growth that occurs at the expense of flowering capability, thus regular pruning for height control is necessary. Chemical pruning using suitable growth retardant may offer similar effects on stem and branch elongation, a...
