  1. Different letters within the column indicate a highly significant difference of mean (±SD) tested by Tukey’s Studentized Range (HSD) at p ≤ 0.01. The data were analyzed from 10 replications of each treatment. L. N., Leaf number; P. H., Plant height; L. B. N., lateral branches number; S. D., Stem diameter (mm); In. L. Inflorescence length; N. F. In. No. of Flower in inflorescence; F. H., Flower height (cm); L. L., Leaf length (cm); L. W., Leaf width (cm); L. D., leaf diameter (mm).
