The influence of centrifugation on the course of microsporogenesis in Tradescantia bracteata (L.)
Journal Title: European Journal of Medical Technologies - Year 2015, Vol 10, Issue 1
Abstract
Centrifugation is one of the laboratory techniques used to separate the mixture into fractions. Microsporogenesis is a process leading to development of microspores in pollen grains. The process consists in meiotic division of pollen mother cells. The aim of the study was to assess the impact of centrifugation on the course of the microsporogenesis process and subsequent development of the pollen grain in Tradescantia bracteata and to check whether centrifuged pollen was able to germinate. The material used in the experiment included stamens of the spiderwort (Tradescantia bracteata) from the family Commelinaceae. The investigations showed a correlation between centrifugation and the arrangement of the anther tissue and cellular structures in pollen grains.
