11 cze 2004 · Defines stigmas as uniquely water-permeant sites on the plant; proteins and lipids are involved in adhesion, hydration, and germination; dry stigmas are pollen compatibility sites, with selective support of pollen hydration and germination, whereas wet stigmas often are covered in exudates from apoptotic cells and block inappropriate ...
