چکیده

The present paper aimed to study the floristic diversity of Dipterocarpus tuberculatus dominated forest of Manipur situated along the Indo-Myanmar Border, north-eastern India. A total of 123 species belonging to 48 families were recorded. The quantitative features such as density and importance value index of species varied greatly. In the present study the diversity index of shrubs and herbs were found to be higher than the tree species. The concentration of dominance was recorded highest in the tree species. The presence of low number of higher girth class of tree species and higher number of the saplings and seedlings indicates that the present forest is young exhibiting frequent regeneration. Resumen: El presente estudio se enfocó en el estudio de la diversidad florística del bosque dominado por Dipterocarpus tuberculatus de Manipur, situado a lo largo de la frontera India-Myanmar, nordeste de la India. Se registró un total de 123 especies pertenecientes a 48 familias. Las características cuantitativas como la densidad y el índice de valor de importancia de las especies variaron considerablemente. El índice de diversidad de arbustos y hierbas fue más alto que el de las especies arbóreas. La mayor concentración de la dominancia fue registrada para las especies arbóreas. La presencia de un número bajo de especies arbóreas de las clases perimétricas más grandes, así como un mayor número de juveniles y plántulas, indican que el bosque actual es joven, mostrando una regeneración frecuente. Resumo: O presente artigo tem por objectivo o estudo da diversidade florística da floresta de Manipur situada ao longo da fronteira Indo-Myanmar, Nordeste da Índia e dominada pela Dipterocarpus tuberculatus. Foram registadas um total de 123 espécies pertencendo a 48 famílias. Os dados mostraram que características quantitativas como a densidade, e o importante índice de valor das espécies eram bastante variáveis. Neste estudo encontrou-se que o índice de diversidade de arbustos e ervas era mais elevado do que os das espécies arbóreas. A concentração de dominância foi encontrada ser mais elevada nas espécies arbóreas. A presença de um pequeno número de espécies arbóreas de classes de perímetro elevadas e elevado número de germinantes e plântulas indica que esta floresta é jovem e exibindo regeneração frequente.

Evaluation of genetic relationship between 15 bamboo species of North-East India based on ISSR marker analysis

The classification of bamboos based on floral morphology and reproductive characters is very hard due to erratic flowering behavior and unusually long reproductive cycle. The application of reliable and effective DNA molecular markers is highly essential to address this problem. In the present investigation, inter-simple sequence repeats (ISSR) markers were employed to study phylogenetic relati...
