Abstract

Fourteen species of bamboo were evaluated for nutritional and fodder quality parameters through metroglyph analysis. On the basis of morphological and qualitative variation in bamboo species scatter diagram was prepared. An examination of the scatter diagram revealed that six groups could be distinguished on the basis of morphological variation. All the species were divided into six groups. Maximum number of species was comprised in group-II (5 species) followed by group-V (4 species) and group-IV (2). From metroglyph and index score analysis, long range of index score was from 16 to 22 observed which itself indicated the large amount of variation in the bamboo species studied.

Abstract

Bamboos are fastest growing plants extensively used for variety of purposes; among them are stock fodder, erosion control and shelter. As a fodder species, bamboos are not potentially investigated and research lacks the qualitative approach of nutritive value found in different species of bamboo. Therefore, work on fodder quality was carried out with fourteen species of bamboo and evaluated for genetic divergence, nutritional and forage quality parameters. Based on divergence analysis of pooled data, the 14 species of bamboo were grouped into four clusters. Cluster I had maximum number of species (7), Cluster III had four species whereas Cluster II and Cluster IV had maximum of (2) and (1) species respectively. Maximum intra-cluster distance was in Cluster II and maximum inter-cluster distance was between cluster II and IV. Correlation analysis revealed that leaf:stem ratio, biomass, crude protein content, dry matter digestibility had major contribution in determining the nutritive potential of green and dry forage yield. Bamboos biomass and nutrient distribution has enormous potential to become a quality fodder for livestock animals. Therefore, bamboo may be planted in a marginal land which makes the soil fertile and produced evergreen biomass round the year.

Abstract

Bamboos serve as multipurpose forest grass species. The success of bamboo as a commercially important forage species depends on the identification of genetically divergent materials of the plant and developing superior planting stock for the farmers. The phylogeny plays a crucial role in the evolution of species and superior germplasm. Twentytwo species of bamboo were evaluated for genetic diversity characterization through SDS-PAGE analysis. Based on electrophoretic pattern, banding pattern was established for 22 species. Also, on genetic diversity analysis, 22 species of bamboo were grouped into four clusters. Cluster IIBb had maximum number of species (9), cluster IIBa and cluster IIAb had four species each, whereas, Cluster IIAa and cluster IA had maximum of two and three species respectively. UPGMA (Unweighed Paired Group Mean Cluster Analysis) inferred that among Bambusa genera; species B. bambusa, B. multiplex, B. vulgaris, B. balcooa, B. tulda, B. nutans, B. polymorpha, B. nutans and B. pallida and among Dendrocalamus species D. hamiltonii, D. giganteus, D. membraneceous and D. longispathus were genetically similar having Jaccard's similarity coefficient ranged from 0.80-1.00.
