Title:

Flowering of Bambusa cacharensis Mazumder in the southern part of North-East India: a case study

Authors:Singha L.B; Bhatt B.P; Khan M.L

Abstract:Flowering in angiosperms is a phenomenon through which the subsequent generation is continued. Some members of the family Poaceae have the suicidal habit, where the parent plants die after flowering. Bamboos, a member of the sub-family Bambusoideae of Poaceae exhibit similar characteristics. Bambusa cacharensis, a species endemic to North-East India, has flowered without producing any viable seeds. Pollen grains studied for their sterility and viability had shown that more than 70% were found to be fertile and viable. A short gynoecium and the unsticky nature of the stigma resulted in failure of fertilization and production of seeds. This natural phenomenon of failure in fertilization has contributed to a reduction of the resource. The destroying of the clumps by the inhabitants of the region has further accelerated this reduction and is contributing to the extinction of the species.
