| Abstract:
The chlormequat chloride (CCC) effects (0, 750, 1500 3000 and 6000 mg•L-1) on the growth index (GI) and flowering of Lantana camara subsp. camara under different levels of shading (0%, 28% and 66%) were determined in 1997 and 1998 in Attica (37°48΄20΄΄N, 23°57΄48΄΄E), Greece. The GI of the CCC treated plants was, in general, increased, significantly at 6000 mg•L-1 compared to smaller concentrations. The increasing shading from 0 to 66% caused a significant increase to the GI of the experimental plants. Increased number of flower heads was observed with increasing concentrations of CCC; this number was significant, in general, to concentrations larger than 1500 mg•L-1 compared to smaller than this, at all shading levels. No permanent chlorosis was noticed on leaves of lantana plants after CCC application. CCC at the concentration of 6000 mg•L-1 could be helpful for the production of robust lantana plants with many flowers for attractive plant fences. | |
