Physiological basis of propagation studies in commercially important difficult to root ornamental shrub <em>Thuja orientais</em>

Abstract

Among different types of cutting, tip cuttings showed early sprouting, highest number of sprouts per cutting per cutting and length of longest sprout. Subsequently, highest number of primary roots per cutting, secondary roots and length of longest root were found with same type of cutting. Among different levels of IBA, IBA at 4000 ppm resulted in early sprouting, maximum number of sprouts per cutting per cutting and length of longest sprout. Subsequently, highest number of primary roots per cutting, secondary roots and length of longest root were found with same treatment. Among two different media used soil + sand + cocopeat + VAM media recorded early sprouting, maximum number of sprouts per cutting per cutting and length of longest sprout. Subsequently, highest number of primary roots per cutting, secondary roots and length of longest root were found with same treatment.
