Since establishment in 1984, the department flourished with tireless efforts of faculties, staff and students. The course curriculum of the department has always been strong and forward looking. Syllabi have been revised regularly and the latest version was done with the introduction of semester system offering five special papers, namely Cytogenetics, Microbiology, Molecular Plant pathology and Fungal Biotechnology, Plant Biochemistry and Taxonomy of Angiosperms and Biosystematics.

    Concept of The Genus Acampe (Lindl.) in India
    (University of North Bengal, 2022) Chakraborty, Oindrila; Agrawala, Dinesh Kumar; Chakraborty, Arka Pratim
    Genus Acampe Lindl. (Orchidaceae) has been taxonomically studied in Indian context. Out of 10 species of Acampe found globally, four species and one variety were recognized in India. Detailed taxonomic account including description, illustrative photo-plate along with information on phenology, habitat and distribution have been provided. The threat status of each taxon has been assessed in Indian perspective by following the IUCN guidelines.

    Conservation of germplasm and role of Centre for Conservation & Utilization of Medicinal and Aromatic Plant of NBU, West Bengal, India
    (University of North Bengal, 2019-03) Chowdhury, M.; Pal, A.; Mondal, S.; Paul, P.; Basak, M.; Chettri, D.; Chowdhury, R.
    Centre for Conservation & Utilization of Medicinal and Aromatic Plant is one of important Herbal garden in India and is located within the campus of University of North Bengal at the foothills of Darjeeling District, West Bengal. Present this ex-situ conservatories houses a total of 729 species of vascular plants belonging to 477 genera and 153 families. Several endemic and threatened species are growing in this garden. The garden is very good store house of various medicinal and aromatic plants and also involve in active research activity.

    Propagation of Ginkgo biloba Linnaeus through air-layering in tropical conditions of West Bengal, India
    (University of North Bengal, 2014-03) Choudhury, Dibakar; Das, A. P.
    Ginkgo biloba Linnaeus (Ginkgoaceac), the maidenhair tree, is recognizably similar to fossils dating back to 270 million years. It is variously used in traditional medicine and as an ornamental plant. Almost no or little attentiíon is given in India regarding its cultivation, conservation and management. The present study established the air-layering technique for the vegetative propagation of the species. As much as 80% of air layering has successfully developed roots. This is a low cost and short duration method through which good number of plants can be produced in tropical conditions, which are expected to be better resistant to different odds and can survive on their own roots.

    Plant wealth of Darjiling and Sikkim Himalayas vis-à-vis conservation
    (University of North Bengal, 2022-03) Das, AP; Ghosh, Chandra
    The richness of the flora of Darjiling Hills along with Sikkim and Nepal parts of the Eastern Himalaya is well known and that has attracted plant lovers, explorers and hunters almost equally for the last three centuries or so. The processes of evolution worked in this part of the Himalayas almost in an undisturbed condition for millions of years assisted by much varied but extremely favourable climatic conditions and has produced innumerable new species, a good proportion of which are still endemic to the region. The vegetation structure and the flora in different parts of this region have developed as per the local climatic make-up. So, when almost tropical vegetation is found on outer low altitude areas, it is sub-alpine to alpine to arctic in high altitude areas especially above 3000 m. Terai and Duars are located at the feet of the hills are maintaining a contiguous rich vegetation. The vegetation scenario in this region is changing very fast during last three or four decades mostly due to anthropogenic activities. Extension of civilisation along with the population explosion lead to the increase in forest extraction, rate of modification of floristic composition, pollution content, soil erosion, plant introduction, clearing of natural vegetation etc. There is evidence that the force of evolution is still active here but the lack of proper corridor (along with other factors mentioned above) for plant migration will certainly cause the weakening of numerous local species and the rate of extinction of species will increase in a logarithmic scale. Like any other part of this planet here also it appears to be one nearly impossible task to save the local biodiversity. Just the declaration of some Protected Areas is not enough. Activities through ecotourism are also affecting the conservation practices. Unless we succeed to conserve the natural vegetation on this planet the entire biosphere will be dead within next 100 years.
