Tenure:
3 Years
Objectives:
i.
Study of diversity of marine algae of different parts of Andaman and
Nicobar groups of islands.
ii.
Collection and identification of marine algae and study of their
ecological parameters.
iii.
Study of developmental stages of selected taxa and seasonal variation.
iv.
Extraction of phycocolloids of some
important species.
Findings:
i.
Alginophytes (Sargassum, Turbinaria and Padina) were located in the
inter-tidal areas near Port Blair in harvestable quantities.
ii.
Sargassum and Turbinaria were having great capacity for regeneration and
wound healing.
iii.
The ultra-structural studies reveal that the young paraphysical cell
contains mitichondrian, ER, prominent nucleus, vacuoles and osmiophilic bodies.
iv. Histochemical studies reveal that the moristoderm cells of the apical region show pyroninophylic cytoplasm, the medullary cells contain prominent nucleus which stains well with DNA, the apical cells of the reproductive and vegetative thalli contain abundant
Benefits:
It serves as an information
pool to the future scientists who are interested
to work on the diversity of
marine algae of Andaman and Nicobar Island which was hitherto unknown to
the present scientific community.
