Developing chloroplast showing starch grains and lipid bodies (Fruit Pericarp)
In mature fruit, cells of the epicarp become thick-walled
and covered with thick corrugated cuticle. The cells consist of
a central large vacuole and relatively less dense peripheral
cytoplasm; the latter has abundance of endoplasmic reticulum.
Mitochondria are seen in large numbers. Chloroplast contains
1-2 starch grains. The abundance of ribosome and ribosomestudded
endoplasmic reticulum in the cytoplasm suggests a
high rate of protein synthesis. The presence of ribosomes in
chloroplasts indicates the protein synthesis capability of
chloroplasts.

Component 6: Aerobiology in relation to pollen production, dispersal and preservation of pollen
grains
Added more data in manuscript entitled “An atlas of
air-borne pollen grains of Lucknow plants and their allergenic
significance”. Collected some fresh polleniferous material to
study pollen production per anther. Photo-documentation of
air-borne pollen grains, graphical presentation of annual pollen
data, correlation of air-borne pollen incidence with
meteorological data and as well as with the patients of allergenic
history visiting KGMC are continued.

Component 7: Floristic and ethnobotanical studies of Bastar (Chhattisgarh) and Shahdol (MP)
districts and automation of herbarium using software
Studied 1,190 plant specimens collected from
Pushprajgarh Range of Anuppur Forest Division (Shahdol
district). This range is characterized by hilly terrain and
undulating topography. People inhabit a very small plain area
scattered throughout the range. Several rivers, channels, nallah
and ponds are the source of water of this area. The climate of
the area is slightly cooler and moist. The area comprises subtropical
vegetation with pure sal forest, mixed forest, scrubs,
grassland and aquatic vegetation. Identified 285 plant species
belonging to 165 genera of 108 families from the above
collection. All the plant specimens have been processed and
poisoned with insecticide and fungicides.
