BIOCHEMICAL-STUDIES ON IPOMOEA POLLEN TO UNDERSTAND SPECIES HOMOLOGY

Studies on pollen phenolic compounds and isozyme profiles of twelve sp ecies of Ipomoea to trace the linkage and homology between the species , through UPGMA method, revealed two broad clusters or groups. The tre nd of clustering and species composition of each group for both the pa rameters were close to each other and almost in accordance with phylog enetic interpretation with minor variations. The variations are probab ly due to the fact that phenolics and isozymes are different biomolecu les.
