Influence of leaf extracts on cultivated turnip VII. meiosis and pollen viability

摘要

Aqueous leaf extracts of periwinkle (Catharanthus roseus Don.), carrot weed (Parthenium hysterophorus L.) and neem (Azadirachta indica A. Juss.) cause a gradual increase in meiotic chromosome abnormalities from lower to higher doses in turnip (Brassica rapa L.). Contrary to this, a progressive decrease in the pollen viability is seen.
