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 ...
Stigma can play an active role in pollen discrimination and some self-incompatibility reactions, that reject pollen from the same or genetically similar plants, involve interaction between the stigma and the surface of the pollen grain.
4 wrz 2021 · Angiosperms are characterized by a great diversity of morphologies, function, and postures of stigmas in their flowers (Endress et al. 1983; Endress 1996). This great diversity has long attracted scientists’ attention for its implication in plant reproduction (Edlund et al. 2004).
9 maj 2020 · The process of plant reproduction is responsible for much of our food supply, with fertility and seed set critical for crop yield and thus food security. The first stage of male–female recognition in flowering plants takes place when pollen lands on the surface of the stigma.
28 maj 2018 · Stigma receptivity is a key prerequisite for successful pollination and seed set in flowering plants. From a plant breeder’s perspective, extending the length of time that the stigma can...
Stigma is the part of a flower's pistil that receives pollen during fertilization. It plays a crucial role in the reproductive process by capturing pollen grains, which are essential for the fertilization of ovules.
