Abstract

Mysore Mallige (Jasminum azoricum L. syn. J. trifoliatum Moench), a popular jasmine of Mysuru district of Karnataka State, India with Geographical Indication (GI) possess unique fragrance. Conservation of this GI tagged cultivar needs immediate attention as it is endangered and area under this crop is decreasing. The present study aimed at rapid multiplication of this threatened species under in vivo condition. Single node cuttings were treated with IBA and IAA for root regeneration and further development of whole plants. While IBA showed best results, single nodes did not respond for IAA treatments. Early sprouting of axillary bud, early formation of leaves, more number of leaves per shoots, highest mean shoot length, maximum number of roots and maximum root length, and better survival percent at 60 days was observed at IBA 1500 mg L-1. However, there was formation of only one shoot in all concentrations of IBA. Untreated single node cuttings showed no response.

Conclusion

Jasmines are normally propagated through semi hard wood cuttings. In the present study. The present study indicates that single node cuttings can be employed for rapid multiplication of Mysore mallige (Jasminum azoricum L.). Single node cuttings responded only to IBA among the two auxins tried. Also, higher concentration of IBA was found most effective in inducing rooting in single nodes and good shoot development along with good survival of the rooted cuttings. The technique can be employed for easy and faster multiplication of Mysore mallige plants.
