Abstract

Bamboos are one of the versatile plant groups with multifarious uses and meet many needs of the society. Bamboo is a viable replacement for wood and industrial raw material for both traditional cottage and modern industrial sectors. The employment potential of bamboo is very high and the major work forces involved are rural poor. The paper elucidates the potential of bamboo as an industrial raw material in various sectors viz., food production, building and construction material, wood substitute, cottage industries, handicraft, pulp and paper, medicinal products, and charcoal production. The paper also explicates the scope of development of domestic and export market for bamboo. With new technical, marketing finesse and renewed commitment, bamboo could take on the role as the material of the future.

Abstract

Thirty-two Bambusa tulda plus clumps were selected using the selection index method and assembled at the germplasm bank of Rain Forest Research Institute, Jorhat. The plus clumps were from different geographical regions of Assam and Meghalaya. Growth study of selected plus clumps in the germplasm bank revealed significant differences among genotypes (at P<0.05 level) for all the parameters height, dbh, and age. The Duncan Multiple Range Test (DMRT) grouped the plus clumps into 15 groups on the basis of height and the plus clump RFRI/BT/511 from Madhavpur of Jorhat district was found to be the best performer (l3.35m), while the plus clump RFRI/BT/502 from Sonapur of Kamrup district was found to be the least best performer. Further, the Duncan Multiple Range Test grouped the plus clumps into 12 groups on the basis of the dbh, with the plus clump RFRI/BT/509 from Balijan, Titabor of Jorhat district (95.32 mm) as the top performer and the plus clump RFRI/BT/502 from Sonapur of Kamrup district as the least best performer. Correlation study showed positive correlation between height and dbh and height was negatively correlated with that of age. A multiple regression model for prediction of height using dbh and age was established.

Abstract

To meet the increasing demand of bamboos for industrial and other uses it is necessary to develop a standardized methodology for selecting plus clumps leading to effective genetic improvement. This has been attempted for some species e.g. Bambusa balcooa, B. bambos, B. nutans, B. pallida, B. tulda and Dendrocalamus hamiltonii. There is need for further investigations to study behaviour, vegetative multiplication of the plus clumps. The growth index for selection is given. Performance trials are in progress.
