Photographs showing the effect of growth regulators on propagation of chinese thuja (thuja orientalis l) in subtropical zone

The present investigation was carried out to study the effect of different growth regulators on propagation of Chinese juniper (Thuja chinensis L) in subtropical zone of West Bengal under natural ventilated polyhouse at Instructional farm of Jaguli, Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, Nadia, West Bengal, during 2014-15 and 2015-16. All parameters were significantly varied among the treatments during investigation (IAA @1000ppm, IAA@2000ppm, IAA @3000ppm, IBA @1000ppm, IBA @2000ppm, IBA @3000ppm, NAA @1000ppm, NAA @2000ppm, NAA @3000ppm, without any treatment (Control) and Local banded hormone(rootex). After studying of two consecutive years, it has been found that tip cutting of this plant treated with NAA (2000-300ppm) followed by IBA at 3000 ppm and IAA at 2000ppm in the month of June is found better for propagation towards of its multiplication in subtropical zone.
