tailieunhanh - In vitro regeneration of capsicum (Capsicum annuum L.) from cotyledon explants

Pre-requisite for any plant biotechnological approach is development of an efficient plant regeneration system in that crop. In this regard the in vitro regeneration was achieved by using cotyledon explants from aseptically raised seedlings of popular Capsicum F1 hybrids Bharat and Indra. Seeds of both hybrids were exposed to different treatments for proper germination, were decontaminated and sown in vitro on half-strength MS medium. The seed soaked in distilled water along with 2 mg/l GA3 for two days prior to sowing had more pronounced effect on both capsicum hybrids recording maximum germination ( and %, respectively) in minimum number of days ( days and days, respectively). | 2017 6 5 225-237 International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 6 Number 5 2017 pp. 225-237 Journal homepage http Original Research Article https In Vitro Regeneration of Capsicum Capsicum annuum L. from Cotyledon Explants Vivek Hegde1 3 .

The regeneration seed soaked in distilled water along with 2 mg l GA3 for two days prior to sowing had Cotyledon more pronounced effect on both capsicum hybrids recording maximum germination Capsicum and respectively in minimum number of days days and days Tissue culture. respectively . Regeneration potential of cotyledonary explants touching the medium both Article Info abaxial and adaxial sides was examined. Tissue culture responses varied with the genotypes side of explants touching the medium and combinations of growth regulators Accepted used. Regeneration per cent number of shoots per explants and per cent 04 April 2017 shoot elongation was maximum in hybrid Indra from cotyledon explant having Available Online abaxial side in contact with growing .
