A study was made on the emerging culm mortality of eight different bamboo species of Bangladesh. Mortality percentage varied from species to species and even from clump to clump. Average mortality percentage varied from 28 to 69 in the case of thick-walled and large dimension bamboo species, and 9 to 37 in the case of thinwalled, small dimension species.

Eco-physiological conditions and genetic make-up of each species and clump seem to influence the rate of mortality of emerging culm in bamboo.
