The Male Germ Unit of Zea mays: Quantitative Ultrastructure and Three-Dimensional Analysis

  • M. L. Rusche

Abstract

Since the concept of the male genu unit was introduced (Dumas et al 1984) a physical association among the elements of the male genu unit has been observed in mature tricellular pollen grains of dicots, in the pollen tubes of dicots with bicellular pollen and in a IIDnocot with bicellular pollen (see Rusche 1988 for references). In IIDnocots with tricellular pollen, a physical association has not been observed in mature pollen.
