IBA Induced Rooting Characteristics in Night Jasmine Plant: Evaluation Using SVI Concept
Journal Title: RA Journal Of Applied Research - Year 2015, Vol 1, Issue 11
Abstract
Rooting ability in IBA induced rooting experiments largely depends on the medium used for rooting this has been established using SVI (sprouting value index), which, is a mathematical approach. Night jasmine plant, Nyctanthes arbor-tristisL. is an ornamental plant with medicinal properties but has poor regeneration capacity from seeds naturally. Field studies were carried out using three rooting medium at a location in Central Kerala, Peninsular India, during June 2014, and repeated at four months regular interval till February 2015. Three IBA (Indole 3-butyric acid) concentrations 100 ppm, 200 ppm and 300 ppm, have been usedand the data obtained was evaluated with SVI (sprouting value index) method in order to evaluate the suitable medium, which gives maximum results. The control cuttings do not recorded rooting. The results obtained indicate high SVI (sprouting value index), when stem root cuttings planted in root trainers with coir pith compost (RTCP) for all the three concentration of IBA applied. Sprouting percentage was increased and the delay in completion of sprouting/rooting initiation decreased by the use of IBA treatment.
