Influence of different growth regulators on propagation of lantana (lantana camara depressa and lantana camara sanguinea) in sub-tropial zone

The present investigation was carried out to study the effect of different growth regulators on propagation of Lantana Spp. in subtropical zone under naturally ventilated polyhouse equipped with foggers at Mandouri farm of Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, Nadia, West Bengal. Significant differences among the treatments (IAA @1000ppm, IAA@2000ppm, IAA @3000ppm, IBA @1000ppm, IBA @2000ppm, IBA @3000ppm, NAA @1000ppm, NAA @2000ppm, NAA @3000ppm and Control) on root emergence and proliferation were noticed. After two consecutive years of studied, (Lantana camara Depressa and Lantana camara Sanguinea), can successfully propagated by tip cutting in the month of June with the treatment of NAA @ 3000 ppm for rapid multiplication of this plant in sub-tropical zone. The second best growth regulators may be considered like IAA @2000ppm, IBA@1000ppm and NAA@ 2000ppm for this purpose.
