Effect of plant growth regulators, type of cutting and season on rooting of carnation (Dianthus caryophyllus L.) cuttings

摘要

The rooting of carnation cuttings as influenced by types of cutting, growth regulators and season was studied. The results revealed that 500 ppm NAA gave the best results in most of the parameters like earliness in rooting, rooting percentage, numberof roots, root length and weight. IAA + IBA + NAA @ 500 ppm each and IAA 500 ppm alone were the next best treatments. Tip cuttings showed better response to growth regulators and rooted better than basal cuttings. Rooting was better in rainy season as compared to winter season except for some shoot parameters.
