Abstract: The flowering in bamboos is an exceptionally interesting event because most of the species flower either gregariously or sporadically only once every 60 to 120 years and this is not all, bamboos are monocarpic, i.e. they flower only once, set seeds and then die. Death in large populations is a cause of concern due to ecological, social and economic crises that set forth. In the past, bamboo flowering was reported to be positively correlated with inflation in rodent population and incidence of famines in the state of Mizoram. Therefore, whenever bamboo flowering is observed in state, scientists and foresters become anxious.
