1995-96 - Birbal Sahni Institute of Palaeobotany

BSIP
Studied thin sections of rocks for organic walled microfossils. The recorded biological
forms show two distinct morphotype : spheroidal cells, and filaments with distinct
hollow structures. They are either solitary or arranged in groups. Asexual reproductive stages,
binary fission and budding are seen. In some slides palmelloid stage is preserved indicating
adverse conditions.

Recorded habit, habitat, frequency, distribution, mode of pollination and duration
of flowering periods of about 75 plant taxa growing in Lucknow city and around. Prepared
a chart of flowering periods of dominant plant taxa. Also prepared both temporary and
pemlanent slides of 115 plant taxa.
Collected and sent the bulk pollen of plant taxa listed to coordinating unit at New
Delhi : Azadlrachta indica, Bauhinia variegata . Cannabis sativa, Cassia jistula. C.
occidentalis, C. siamea, Cyperus rotundus, Parthenium hysterophon/s, Polyalthia
longifolia, Terminalia arjuna, Delonix regia, Aegle marmelos, Amaranthlls spinoslls,
Acacia arabica, A. auriculeformis, Zea mays, Sorghum vulgare, Tamarindus indica,
Xanthium strumarium, Prosopisjuliflora. Also sent the pure culture of fungal taxa like
Aspergillus jiavus, A. tamarii, A. niger, A. nidulans, A. carneus, A.•niveus, Fusarium
oxysporum, Penicillium citrunum, Curvularia lunata, Chaetomium globosum,
