Chronopoulou-Sereli Journal of Animal and Plant Sciences JAPS 20152015/10/01 25 5 1371-1376 1018-7081 NA <p>The creation of high quality plants and their maintenance depends, primarily, on proper fertilization, deriving mainly from the knowledge of their nutrient requirements (NR). Spray-applied chlormequat chloride (CCC), at the concentrations of 3000 and 6000 mg L-1, has been reported to contribute to the production of attractively flowering&nbsp;<em>Lantana</em>&nbsp;<em>camara</em>&nbsp;L. subsp.&nbsp;<em>camara</em>&nbsp;(lantana) plants. However, no information is available about the NR of these plants. The effects of the aforementioned CCC concentrations plus 0 mg &nbsp;L-1 (control) on specific leaf area (SLA) and leaf potassium (K), phosphorus (P), calcium (Ca), iron (Fe) and manganese (Mn) contents of lantanas were examined under the 0% and 66% shading levels. Chlormequat chloride (3000 and 6000 mg L-1) decreased, generally, SLA of lantanas compared to control, at both shadings. Increased SLA values were estimated with increased shading. Phosphorus content increased with the increased CCC concentrations at 66% shading level. Phosphorus and Fe contents increased while Ca and Mn decreased with the increasing shading. The results of our study may contribute to the planning of a fertilization program for CCC-treated&nbsp;<em>Lantana&nbsp;</em>plants, a promising genus in landscaping in many countries around the world.</p> Chlormequat chloride; Lantana camara L.; nutrition; onium-type regulator; specific leaf area; photosynthetic photon flux Pakistan Agricultural Scientists Forum https://thejaps.org.pk/AbstractView.aspx?mid=2015-JAPS-187
