ABSTRACT
The present investigation entitled, “Effect of propagation on propagation of LA 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 2013-2014. The experiment was laid out in a Completely Randomized Design (factorial) consisting of three cultivars and six calcium nitrate doses (0, 5, 10, 15, 20 and 25 g/m2). Among the cutivars, maximum bulblet multiplication was shown by ‘UHFS LA Lily Collection 1’ (2.59) followed by ‘Batistero’(2.48) and ‘Frans Hals’(2.32), respectively. Among the different calcium nitrate doses, 10 g/m2 calcium nitrate dose gave best results for per cent sprouting (76.03 %), days taken for sprouting (102.00 days), sprout length (9.60 cm), fresh weight of bulblet/scale (1.69 g), bulblet diameter (9.32 mm) and propagation index (125.69 %) when supplied to the scales in ten equal split doses in liquid form. However, for obtaining higher number of leaves/scale (6.38) and maximum multiplication (2.90 bulblets/scale) calcium nitrate application at the rate of 20 g/m2 supplied to thes scales proved to be most effective treatment. The interaction between cultivars and calcium nitrate doses have shown variable responses. Percent sprouting was observed maximum in ‘Frans Hals’ (77.14 %) with 15 g/m2 and 25 g/m2 calcium nitrate and in ‘UHFS LA Lily Collection 1’ (77.14 %) with 10 g/m2, maximum sprout length (10.18 cm), number of bulblets/scale (3.01) and bulblet diameter (9.77 mm) in cultivar ‘UHFS LA Lily Collection 1’ with 10 g/m2 and maximum number of leaves/scale (7.03) in cultivar ‘Batistero’ with 25 g/m2 calcium nitrate dose.
