The reduction in yield appeared related to a decrease in pollen germination and tube elongation associated with acidic conditions and limited quantities of pollen available for pollination. Germination and tube elongation of pollen were inhibited when grown on an agar medium acidified to pH 4.6 with simulated rain. Germination of pollen grains was reduced as much as 75% on silks previously exposed to a simulated rain of pH 3.6 asCollection: AGRIS Collection
