Abstract
The male gametophyte of higher plants is metabolically active; during microspore maturation, grain germination and tube growth, the most important physiological processes are those related to respiration, reserve mobilization, nutrient uptake, biosynthesis first of intine and then of pollen tube wall (3). Pollen is also able to respond to environment; this ability is expressed both in physiological interaction with stylar tissues during tube development, and in relation to environmental stresses, toxic products, pathogens (8). The responses are generally correlated to sporophytic behaviour (7,9).
