12 HABIT

13 Trees or shrubs; very rarely herbs Tree species at lower elevations and in tropical climate Ex. Dendrocalamus strictus Under shrubs at higher elevations in temperate regions Ex. Arundinaria prainii At high altitudes, some species are herbaceous Ex. Buergersiochloaspp. Scandent climbers Ex. Chusquea abutifolia GLOBAL BAMBOO SUBMIT, INDORE 2016

14 MORPHOLOGY CULMS

15 Culms are woody pointed stems Arise from underground rhizomes Generally clustered Generally, culms are devoid of branches for considerable height above base Height ranges from 2-6 m. in Ochlandra travancorica to 30m. in Bambusa bambos Diameter varies from 2.5 cms. in O.travancorica to 18 cms. in D. hamiltonii GLOBAL BAMBOO SUBMIT, INDORE 2016

16 Wall thickness Thick walls Ex. Dendrocalamus strictus Thin walls Ex. Melocanna bambusoides Contd. Hollowness Solid culms (Male baboos) Hollow, round, smooth culms with transverse septa at the nodes (Female bamboos) Clump formation habit Clump forming bamboos with sympodial (pachymorph) rhizomes Ex. Dendrocalamus, Bambusa Non-clump forming bamboos with monopodial (leptomorph) rhizome Ex. Arundinaria, Phyllostachys GLOBAL BAMBOO SUBMIT, INDORE 2016

17 GLOBAL DISTRIBUTION

44 Bamboo species differ in Habit Rhizome type Flowering behavior Silivicultural requirements Howllowness Fibre length Fibre strength Growth rate/ productivity Culm thickness Utilization pattern Even within same species, significant variations in different Phenotypes Genotypes Variations useful in developing hybrid varieties with desired traits Factors governing choice of species for propagation Edapho-climatic conditions Productivity Intended uses Market demand GLOBAL BAMBOO SUBMIT, INDORE 2016

45 NEED FOR COLLECTION & CONSERVATION OF GERMPLASM

46 Genetic erosion of several bamboo species due to high biotic pressure and destructive harvesting. The diversity of this fascinating plant has to be conserved, not just for financial reasons, but also more importantly for ensuring livelihood of dependent populations. Selection, improvement and conservation of available genetic resource should receive highest priority. Efforts have been made by NBPGR, ICFRE, State forestry research institutes and ICAR GLOBAL BAMBOO SUBMIT, INDORE 2016

47 INITIATIVES FOR CONSERVATION OF BAMBOO DIVERSITY

48 Key areas for conservation of bamboo diversity in India identified by WII. KFRI established Bamboo Information Center (BIC) of 137 Indian bamboo species. Ex-situ conservation and tissue culture work started in India and other countries for large scale propagation. ICFRE, State forestry research institutes, private companies and State Forest Departments are propagating bamboo. GLOBAL BAMBOO SUBMIT, INDORE 2016

Bamboo introduction started during late 1970s Kerala Forest Research Institute, Peechi Bamboo introduction started during early 1990s Van Vigyan Kendra, Chessa (Arunachal Pradesh) Bamboo introduction started during 1980s GLOBAL BAMBOO SUBMIT, INDORE 2016

51 FUTURE STRATEGY FOR CONSERVATION OF BAMBOO DIVERSITY

52 Study of bamboo flora in PAs Establishment of new PAs for bamboo species Establishment of bambuseta/germplasm banks/botanical gardens, exclusively devoted to conservation of bamboo species Performance assessment of germplasm Preparation and regular updating of catalogue of bamboo germplasm GLOBAL BAMBOO SUBMIT, INDORE 2016

53 Integrated R&D efforts Molecular biotechnological techniques Contd. Genetic diversity assessment using different molecular markers Genetic improvement Genome profiling through DNA fingerprinting RGA (Resistance gene analogue) based allelic polymorphism to assess disease tolerance Induced flowering through in vitro techniques Selection of disease tolerant genotypes Breeding Development of improved cultivars Package of practices for cultivation, production and utilization Development of protocols for macro and micropropagation GLOBAL BAMBOO SUBMIT, INDORE 2016
