Past and Present activities of the group

  • Pollen morphology in relation to plant taxonomy of the following taxa:
    a) Indian Monocotyledons
    b) Indian Dicotyledons: Asterales, Geraniales, Malvales, Ranales, Rosales, Heteromerae, Monochlamydeae
  • Melittopalynology:
    a) Pollen analysis of Indian honeys
    b) Pollen analysis of bee-loads
    c) Pollen analysis of seasonal honeys of western Himalayan regions
    d) Pollen analysis of honeys from Gangetic plain
  • Aerobiology & Allergy: Conducted an All India Coordinated Project on Aerobiology for identification of aeroallergens
  • Cytopalynology in relation to biosystematics in Amaranthus, Arachis, Argemone, Celosia, Chenopodium, Chorisia, Gloriosa, Sisymbrium irio-complex and Solanum.
  • Crop palynology: Pollen ultrastructure in crop plants (e.g. Cajanus, Cicer, Oryza, Sorghum and Saccharum) and their wild relatives.
  • Effect of radiation on pollen features.
  • Pollination ecology of agriculture crops and some endangered plants.
 
Objectives

  • To study the ultrastructure of pollen wall.
  • To describe and illustrate pollen grains and evaluate their taxonomic and phylogenetic value leading to the preparation of Pollen flora of India.
  • To describe and illustrate the basic palynological data including ultrastructure of pollen grains of medicinal plants of India.
  • To undertake studies on pollen morphology in relation to cultivar taxonomy and to fix morphological parameters of pollen for various cytotypes of wild and cultivated plants.
  • To establish a National Pollen Herbarium of both wild and cultivated plants of India.
  • To undertake studies involving qualitative and quantitative analysis of airborne and honey pollen flora of India.
  • To assess the pollinator's potentiality in the yield of some agriculture crops.
 
Salient Achievements

  • A new concept has been introduced in plant biosystematics through cytopalynology for study and identification of cytotypes in nature and for the assessment of inheritance pattern in pollen morphology in the hybrids.
     
  • Aeroallergens occurring in various physiographic zones of India have been identified.
     
  • By honey pollen analysis seasonal honey flora of the western Himalayan regions and upper Gangetic plain have been identified.
     
  • By the analysis of bee collected pollen loads, bee forage plants of several different geographic regions have been identified.
     
  • Through ultrastructural studies of pollen, interrelationships and affinities have been established between the cultivated crop plants and their wild relatives.
     
  • Through ultrastructural studies, distinguishing exine patterns have been identified in subgeneric and subspecies level in some important poaceous crops which was so far undistinguishable.
 
Educative Aid
 
A standard pollen kit comprising of an informative booklet and pollen slides containing various characteristic morphotypes has been prepared for practical demonstration in teaching Institutes and Universities.
 
 
Publications

More than 260 research publications have been published, which include several monographs on various groups of angiosperms on pollen morphology in relation to plant taxonomy.
