11 cze 2004 · In this review, we (1) survey recent discoveries of pollen and stigma functions both before and after they make contact, and (2) address the great diversity in pollen and stigma structures across taxa, focusing on how they accomplish key tasks in pollination.
24 gru 2021 · Stigma is a part of the female reproductive structure of the flower. It comprises the pistil, a part of the gynoecium or female reproductive organ of a plant, together with two other structures, the style, and ovary. Stigma is a specially adapted portion of the pistil modified for pollen reception. Stigma Flower.

8 cze 2018 · The stigmas of flowering plants selectively recognize pollen from the same species in part through biochemical interactions.
This chapter aims to show the range of morphological variation in stigma types found throughout the angiosperms, to enable classification of stigmata into the major recognized groups, and to indicate the relationship between structure and function.
1 sty 2007 · Recent years, studies indicated that stigma closure may increase pollen capture and receipt, improve pollen germination and pollen tube growth, and prevent intra-floral selfing.
