Popis: Dendrocalamus longispathus Kurz clumps located in Mamit District, Mizoram, India was observed to study the quality and quantity of seed produced during the sporadic flowering as an ecological indicator for further flowering precaution in Mizoram. Soil seed bank and seed drop quantity of seeds in a culm were estimted for further afforestation of D. longispathus in a barren or wasteland lands in tropical sloppy mountainous conditions. The study would be applicable in reforestation, programme by dispersing the collected seeds into a forest areas decreasing in numbers of D. longispathus. The study between the disturbed site and undisturbed site compared to understand the difference between the two sites in terms of their seed quantity, seed drop, seed viability and soil seed bank. The number of seed produced by a flowering D. longispathus culm was higher in undisturbed bamboo forest. Seed viability test using tissue paper test indicated that there was 50.5% and 55.7% viability for disturbed and undisturbed sites respectively. However, using 1% solution of 2, 3, 5-triphenyltetrazolium chloride from a disturbed and undisturbed sitess showed 52.2 % and 56 % viability respectively. Adoption of scientific management techniques advocated for both bamboo plantations and natural bamboo forests to improve the quality and growing stock volume of bamboo in Mizoram.
