Cytology of pollen with particular reference to Impatiens and Allieae

Abstract

From the foregoing accounts, a logical conclusion emerges, that while pollen mitosis cannot replace the cytological studies based on pollen mother-cells and root-tips, more often than not, it forms an excellent adjunct to them. Apart from the study of pollen nitosis there are many other very interesting problems in pollen cytology, about which we have no clear understanding. These pertain mostly to the problems of cytoplasmic gradient and differentiation within the pollen grain.
