    Effect of indole butyric acid and callusing period on rooting and growth of kair (Capparis decidua L.) cuttings
    (CCSHAU, 2006) Kamal Kumar; Sharma, Jeet Ram
    The present investigation on “Effect of Indole Butyric Acid and callusing period on rooting and growth of Kair (Capparis decidua L.) cuttings” was carried out during 2005-06, in the nursery of the Centre for Research and Application and Plant Tissue Culture, CCS HAU, Hisar. The mature cuttings were collected during November-December and after giving treatment with different concentrations of IBA (0, 1000, 1500, 2000, 2500, 3000, 3500 and 4000 ppm) for one hour, all the cuttings except 0 day were buried in soil approximately 3 feet deep in optimum moist sand for callus formation. Initiation and duration of sprouting (days) of cuttings were reduced with the application of growth regulator. The cuttings treated with IBA 4000 ppm took minimum number of days followed by IBA 3500 ppm in the initiation of sprouting of cuttings. Percentage of sprouting and survival increased significantly with the IBA treatment over control. Higher number of roots per cutting, average root length, maximum (longest) root length and maximum root number per cutting was recorded with 4000 ppm IBA followed by 3500 ppm IBA treatmen. Height and girth of main shoot were significantly higher in cuttings treated with 4000 ppm followed by 3500 ppm over control treatment. Further callusing treatment has been reported to reduce root and shoot growth as compared to without callusing treatment. The cutting with 60 days callusing period did not sprout because of heavy infestation of fungi, which damaged the callus formation. The cuttings planted with 0 day callusing (without callusing) treatment sprouted much earlier than the cuttings planted 30 and 45 days after callusing. The degree of success in terms of sprouting and survival percentage, number of shoots per cutting, height of main shoot, girth of main shoot, initiation of sprouting of cutting, average root length, maximum (longest) root length, number of roots per cutting, fresh and dry weight of shoot, fresh and dry weight of roots were significantly better in 0 day (without callusing) callusing treatment than 30 and 45 days callusing period.
