Effect of auxins and cytokinin on budding and growth of saplings of bael (Aegle marmelos Correa.)- a medicinal plant
Keywords:
Bael (Aegle marmelos Correa.), budding, growth regulators (NAA, IBA, BA)Abstract
In this investigation, NB-9 cultivar of bael (Aegle marmelos Correa.) was selected as mother plant for obtaining scion bud. The foliar spray of NAA, IBA and BA (25 and 50 ppm each) either on rootstock or/and scion branch was applied seven days prior to budding. The most responsive treatment was foliar spray on rootstocks with BA at 50 ppm concentration. Rootstocks treated with BA (50 ppm) resulted in early bud breaking (10.67 days), maximum bud sprouting percentage (100%), length of sprouted scion 30 days after budding (22 cm), diameter of sprouted scion (2.53 mm), number of leaves (7.13) and maximum scion growth initiation in plants (87.50%) as compared to other treatments. In another experiment, when plant growth regulators were applied to scion branch of mother plant at seven days prior to budding, did not respond satisfactorily with respect to almost all the parameters except bud sprouting percentage and bud survival percentage. These treatments failed to have promotive effect on length of scion shoot and percentage of plants with scion growth.
