ABSTRACT
The present investigation entitled, “Studies on propagation of hybrid lilies through scaling” was carried out at the experimental farm of Department of Floriculture and Landscape Architecture, Dr. Y.S. Parmar University of Horticulture and Forestry, Nauni, Solan, (H.P) during 2014-2015. The first experiment was laid out in a Completely Randomized Design (factorial) consisting of three cultivars, three media and four auxin treatments (control, NAA 500 ppm, IBA 500 ppm, NAA 500 ppm + IBA 500 ppm). Among the cutivars, maximum weight of bulblets/scale (0.51 g) and propagation index (41.90%) was recorded in cv. ‘Batistero’, maximum number of bulblets/scale (2.53) in cv. ‘Jazz It Up’ and bulblet diameter in cv. ‘Courier’ (8.60 mm). Among the different auxin treatments, dipping the scales in NAA 500 ppm before planting produced best results for per cent sprouting (65.56 %), days taken for sprouting (66.19 days), sprout length (15.83 cm), number of leaves/scale (2.21), percentage of scales showing bulblet formation (69.63 %), number of bulblets/scale (2.68), weight of bulblet(s)/scale (0.57 g), bulblet diameter (9.42 mm) and propagation index (39.77 %). Out of the media, per cent sprouting (66.67 %), days taken for sprouting (73.36 days), sprout length (16.41cm), percentage of scales showing bulblet formation (67.50 %), number of bulblets/scale (2.67) and propagation index (38.16 %) was maximum in ‘cocopeat’ whereas, number of leaves/scale (2.22), weight of bulblet(s)/scale (0.68 g) and bulblet diameter (9.86 mm) was observed maximum in perlite + vermiculite. Finally, it was concluded that an application of 500 ppm NAA and planting in cocopeat was found to be the best treatment for propagation of lilium through scaling. In the second experiment, the scales of fifteen Asiatic and LA hybrid lily cultivars were planted in cocopeat after dipping in NAA 500 ppm. It was found that, cv. ‘Batistero’ excelled others with respect to most of the parameters and maximum propagation index (80.48 %) was also recorded in this cultivar.
