Under potted conditions, application of MH @ 600 ppm resulted in maximum, number of leaves per plant and root-shoot ratio as compared to other treatments. The maximum length of the leaves was observed in the control plants which was followed by cycocel @ 500 ppm. Foliar application of cycocel @ 1500 ppm recorded the maximum leaf width when compared to other treatments. Significant differences were observed with the various flowering attributes upon the application of growth retardants. It was observed that maleic hydrazide @ 600 ppm recorded maximum florets per spike, longevity of spike in field, longevity of florets on the spike. The maximum floret length was observed with cycocel @ 1500 ppm. The minimum length of floret, longevity of spike in the field and longevity of floret on spike was observed with the application of paclobutrazol @ 1500 ppm.

Crossandra, cycocel, paclobutrazol, maleic hydrazide

Based on the data, it can be concluded that foliar spraying of MH @ 600 ppm was advantageous for efficiently suppressing vegetative growth while having no negative effect on crossandra blooming and rooting properties.
