Effect of scale position on In-vivo growth and multiplication of bulblets from Bulb-Scale of different asiatic Lilium hybrids during scale propagation

An experiment was carried out to investigate the effect of scale position on growth & multiplication of bulblets from bulb-scale of different Asiatic Lilium hybrids during scale propagation. For this purpose scales detached from bulbs of five different Lilium varieties were separated into three groups according to their anatomical position on the mother bulbs. The results of the study revealed that maximum sprouting of scales (77.78%), survival rate of sprouted plantlets (83.33%) and number of bulblets per scale (10.67) were recorded in middle scale of Nov cento. However most number of roots (11.66), length of longest root (15.33cm), circumference (9.45cm) and weight of individual bulblets per scales (44.43g) were found maximum under middle scale of new wave. Besides maximum weight of total number bulblets per scale (213.16g) was obtained from middle scale of Alaska. On the other hand combination of variety Monte Negro with outer scale exhibited very poor performance with respect to most of the parameters. Irrespective to the Lilium varieties middle scale performed better than outer and inner scales. So for in vivo multiplication of bulblets, middle scales of mother bulbs must be used for horticultural production purposes.
