Study on Positions of Twin Scales and Growth Regulators on Propagation of Narcissus (Daffodil) cv. Stamen Cream

Abstract

Study was carried out to evaluate the influence of position of twin scales and growth regulators on propagation of Narcissus (Daffodil) cv. Stamen creamx. Results of the study reveals that out of eight treatment combinations tested in the experiment minimum days for callus initiation (26.00 days),root initiation (36.50 days) and bud initiation (44.50 days) after incubation resulted with combination of outer scales treated with IBA 100 ppm. Further maximum number of buds per chip (2.00), bud diameter (11.95 mm), bud length (2.76 cm) and bud weight (0.41g) were recorded with the same treatment. Inner scales treated with IBA 100PPM resulted with maximum days for callus initiation (37.50 days), root initiation (48.00 days) and bud initiation (60.50 days) after incubation. Least number of buds per chip (1.00), minimum bud diameter (7.45 mm), bud length (1.30 cm) and bud weight (0.19 g) were also recorded with same treatment. Most of the differences among the treatments for almost all recorded parameters were statistically significant.
