Abstract
The present investigation entitled “Studies on clonal multiplication in Alstroemeria”, comprising three experiment was carried out during the year 2007. The trial was laid out in polybags under 35 per cent shade net. In the first experiment nine growing media viz., soil + sand (1 : 1), soil + sand + FYM (1 : 1 : 1), soil + sand + FYM (1 : 2 : 1), soil + and + FYM ( 1: 1: 2), soil + cocopeat + sand (1 : 1 : 1), soil + sand + cocopeat (1 : 2: 1) soil + sand + cocopeat (1 : 1: 2), sand + FYM (1 : 1) and sand + cocopeat (1: 1) were tested for their influence on shoot and rhizome development. Among the growing media soil + sand + cocopeat (1 : 1 : 2) performed better with respect to all the parameters studied including propagation coefficient whereas, media containing sand + cocopeat (1 :1) performed poorly. In the second experiment, the effect of three storage roots (0, 1-2, 2-4) and four BA levels (0, 20 40 and 60 ppm) was studied on the multiplication efficacy in Alstroemeria cv. ‘Pluto’. Benzyladenine 60 ppm concentration increased all the parameters studied including days to sprout, per cent sprouting, propagation coefficient but could not improve the per cent established plants, number of vegetative shoots at 90 and 120 days after planting (DAP) and weight of the rhizome cluster. Whereas, among the storage root number, the rhizomes having 2-4 storage roots performed best. In the third experiment, the effect of three storage roots (0, 1-2, 2-4) and four N levels (50, 100, 150, 200 ppm) was studied for their influence on shoot and rhizome development. Perusal of data revealed that highest dose of nitrogen i.e., 200 ppm improved all the parameters including propagation coefficient whereas, among the storage root number, rhizome with 2-4 storage roots proved superior in recording the studied parameters in comparison to other treatments during the present study.
