Abstract
We studied in situ pollen germination in natural populations of Viola canescens Wall., V. biflora L. and V. patrinii Ging., where a part of pollen grains shows a precocious germination while in the anther. In situ germinated pollen tube showed some abnormality in structure that may be due to non-availability of microenvironment. Rest of pollens exhibits the normal dispersal after anther dehiscence and germination on compatible stigma. This phenomenon may contribute to the reproductive efficiency.
