| Summary, etc. | A comparative evaluation of the morphological and anatomical features as well as reproductive biology of the three species of Plumbago viz., P.rosea, P. zeylanica and P. capensis was carried out in the Department of Plant Breeding and Genetics during 1997-1999 with a view to find out the relationship existing among the species and to prepare a key for their identification. The different species of Plumbago varied with respect to nature of stem and leaves, colour of petiole, leaf attachment etc. Significant variations were also observed in the length of inflorescence, number of flowers per inflorescence time taken for completion of anthesis per inflorescence and size and colour of floral parts. Though there was uniformity in the fundamental structure of the stem, variations were observed in the outline of T.S., size of epidermal cells and arrangement of chlorenchyma. In the case of root, variability was observed in thickness of cortex, nature of stone cells, presence of starch grains etc. Study of reproductive biology revealed that anthesis occurred earlier in P. zeylanica compared to other two species. Further the period of anthesis also extended over a wide time range in P. zeylanica. Eventhough the pollengrains were tricolpate and spherical •in all the three species, differences existed with respect to colour, size and fertility of pollen grains. Coincidence of pollen dehiscence and stigma receptivity was found to lead good seed set in P. zeylanica. Apis spp. and wind were observed to be the main pollinating agents. Based on the different morphological, anatomical and reproductive characters a key for the identification of the different species were proposed. A distance matrix based on morphological anatomical and reproductive characters of three species revealed that P. rosea and P. zeylanica are more related than P. capensis. |
