  1. Clonal Propagation of BambusavulgarisSchrad ex wendl by Leafy Branch Cuttings M. A. Hossain University of Chittagong, Bangladesh Korea University, Korea

  2. Bamboos in Bangladesh 33 Species: 7 wild species in forests 26 domesticated Bambusa vulgaris (Baijja Bansh): most widely used bamboo species in rural Bangladesh • Widely used in • Building construction • House making • Agricultural implements • Fishing traps • Improvised bridge on small canel • Making household products Bambusavulgarisgroove

  3. Propagation methods.. • Do not set seed after flowering, no seedling progeny • Propagate only through Vegetative methods 1. Rhizome cutting • Low survival rate • Bulkiness of (20-30Kg) of rhizomes • Expensive option Rhizome cutting

  4. Propagation methods.. 2. Pre-rooted branch cutting • Easiest method • Limited only to wet seasons • Very few branches develop root at their base (Banik,1997 )

  5. Propagation methods.. 3. Secondary branch cutting Hossain et al. J. Bamboo and Rattan, 2005, 4 (3), 231–241

  6. Propagation methods.. 4. Primary and Secondary branch cutting Hossain et al., J. Bamboo and Rattan, 2006, 5 (3&4),117-126 • Convenient • The numbers of suitable branches (>5mm dia.) to produced root are inadequate. • Limited only to rainy season during June-July.

  7. Propagation by Leafy Branch Cuttings • Regeneration from leafy brunch cuttings • Nodal leafy cuttings • Tip cuttings • Effect of IBA on rooting ability of leafy branch cuttings • - 0%, 0.1%, 0.4% and 0.8% IBA Solution

  8. Experimental procedure Nodal leafy cuttings Tip cuttings Non-mist propagator 4-6 weeks Propagule ready for planting Propagules in nursery bed (6 months old ) Cutlings in polybag (2 months) Rooted cuttings

  9. Results.. Rooting percentage

  10. Results.. Root number Nodal leafy cuttings Tip cuttings

  11. Results.. Root length

  12. Results.. Survival percentage Tip cuttings Nodal leafy cuttings

  13. Results.. Growth performance Nodal leafy cuttings Tip cuttings

  14. Summary of findings • Nodal leafy cutting and tip cuttings, both produced roots, survived and formed rhizome. • The highest rooting percentage and root number per cutting was in 0.8% IBA treated cuttings. • IBA treated cuttings showed better survival capacity in the nursery condition over controlled one. • The result presented here could help in opening a new avenue for the mass propagation of this variety bamboo species.

  15. Further aspects • The rooting percentage of leafy branch cuttings of B. vulgaris in this study was 56. There is scope to increase the rooting ability of cuttings of the species. • Furthermore, the performance of planting stock developed through the methods was not assessed in field condition. This might be one of the important aspects for future study.
