Description :
The pollen grains are smallest unit of the plants, which contain so many characters of taxonomic and
phylogenetic importance. The shape and size of the pollen grains, germinal furrows and the number of germ pores are
important taxonomic features, which are taken into consideration in classification of plants.Now a days study of pollen
is an important area of research. Various pollen morphological features such as symmetry, shape, apertural pattern and
exine configuration are very conservative features for the taxonomic assessment of the plant. Moreover some plants
growing in the surroundings cause respiratory troubles or allergy in human beings. The pollen grains of which are
responsible for allergy. Considering an immense importance of pollen grains with respect to pollen allergy the present
work has been initiated for the research study. For the present research work weeds Oxalis corniculata (Oxalidaceae)
and Tridax procumbens (Asteraceae) which are highly allergic with respect to pollen allergy are selected. Comparative
study of pollen production of selected plants is studied by glycerin suspension method and haemocytometer method. In
Oxalis corniculata pollen production by glycerin suspension method was found to be 80 whereas by haemocytometer
method 217. In Tridax procumbens pollen production by glycerin suspension method was found to be 2044.5 whereas
by haemocytometer method 314. The variation occurs in number of pollen grains produced per anther because pollen
production is affected by distribution, habit of plant and difference in climatic conditions.
