Abstract
In controlled environment, the effective pollination period in Larix leptolepis is characterized by its brevity, lasting for less than 1 d. It is associated with the opening of the papillae of the pollen collecting apparatus which possess surface esterase activity, a condition that has its parallel in the surface pellicle of angiosperm stigmas.
