self-pollination

the transfer of pollen from the stamen of a flower either to the stigma of the same flower or to another flower on the same plant. Since self-pollination leads to self-fertilization which is a form of inbreeding, many plants have developed mechanisms to prevent its occurrence. For example, plants can be DIOECIOUS, show SELF-INCOMPATIBILITY, and have differential maturation times of male and female floral organs on the same plants (for example, see ARUM LILY). Compare CROSS-POLLINATION.

05), indicating that the effects of procedures on the fruit set percentage depended on the time when flowers are self-pollinated (Table 1).
Besides rice, the present study can also be extended to other vegetatively propagated or self-pollinated crops.
Self-pollinated plants are usually genetically homozygous with both alleles of a given gene being identical (i.
When F1 plants are self-pollinated, the checkerboard method of predicting how the gametes will combine corresponds closely with what Mendel actually observed: nine yellow and round, three yellow and wrinkled, three green and round, and one green and wrinkled (refer to Table 5-3).
In particular, flowers pollinated with outcross pollen produced seeds with significantly higher germination frequency and seedling mass than flowers pollinated with self pollen, whereas seed set was higher in fruit from self-pollinated flowers (Fig.
Some genotypes were experimentally self-pollinated in at least three different years.
Carefully, he saved the seeds produced by each self-pollinated plant, planted them separately, and studied the new generation.
0 represented highly resistant with no symptom, 0; represented small necrosis but no sporulation, 0;+ represented larger or necrosis without sporulation, 1 represented some necrosis with only a trace of to slight sporulation, 1+ for chlorosis and necrosis associated with 1imited uredium development, 2 represented chlorosis flecks or necrosis with moderately sporulation, 2+ for chlorosis and necrosis among abundant - to get the F1 seeds and the F1 plants were self-pollinated to interrnediate spolulation, 3 for chlorosis and necrosis obtain F2 seeds, which were used in allelic analysis reseach; MX169 as female and male was crossed with Early Premium.
Self-compatibility index (SCI) was estimated by dividing the number of fruits or seeds produced in self-pollinated (SP) flowers by the number of fruits or seeds from cross-pollinated (CP) flowers.
According to Baker & Baker (1983) starchy pollen grains are generally considered to be characteristics of species that are self-pollinated, wind pollinated, pollinated by Lepidoptera or by birds, while lipidic pollen grains are characteristics that have species of bee-pollination and flypollination.
