Abstract:The study aimed at evaluating germplasm of Dendrocalamus stocksii for growth and material quality parameters using non-destructive technique. In the study, ultrasonic pulse propagation method for evaluating modulus of elasticity of bamboo material and assessing hollowness was explored. There was significant variation in internode length and diameter in mature culms of clumps from the 36 accessions in the germplasm bank. The ultrasonic pulse velocity varied from 2.74 to 4.05 km/s among the clumps indicating more than two folds variation in modulus of elasticity of bamboo material. Ultrasonic pulse velocity across the diameter of less than 0.85km/s indicated hollowness in the culm. The growth parameters in combination with non-destructive ultrasonic pulse propagation method can effectively be used for screening of superior accession or genotypes of bamboo species in future improvement programmes in D.stocksii
