Abstract
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.
