which connects both the stigma and ovary. The pollen tube contains the male gametes, eventually fusing with the egg cell inside the embryo sac. Fusion of the male gamete and egg is termed fertilization, which forms

11.4 Pollination and fertilization Pollination consists in the transport of the pollen grain from the anther to the stigma, where it is deposited. This process can be carried out with pollen grains from the same plant, or from another plant; in the first case the process is called self-polli...
Pollination is an important part of the life cycle of plants that produce seeds. Like animals, plants generate new plants using sexual reproduction – the combining of egg and sperm cells, known as fertilization. Pollination is what leads to fertilization. As in animals, fertilization is all abou...
Flower structures are designed with the intent to maximize fertilization. Perfect flowers include petals and sepals that surround the sexual parts of the flower, which are the pistil and stamen. The pistil is the female part of the flower and the stamen is the male part of the flower. Explain...
Thomas Andrew Knight, after experiments on the cross-fertilization of cultivated plants, formulated the conclusion that no plant fertilizes itself through many generations. Sprengel's work, which had been almost forgotten, was taken up again by Charles Darwin, who concluded that no organic being can...

and fertilization is made up of a particular pollinator–plant pair. With some small positive value\({\it{\epsilon }}\), such that\(r_F = {\it{\epsilon }}\), we can model a highly specialized pollinator mutualism, whererFcontributes slightly to plant reproduction and the pollinator is ...
To investigate the influences of GX cross-pollination and self-pollination on the fertilization and ovary development. The pollens of GX and SJ were pollinated to SJ stigmas in March 2017, respectively. At six days post pollination, ovaries were collected and divided into two groups. Ovaries of...
