How To Use Self-pollination In A Sentence
-
As for calculation of the selfing rate, self-pollination was with pollen from other flowers of the same plant.
-
Pollination can be cross-pollination with a pollinator and an external pollenizer, self-pollenization with a pollinator, or self-pollination without any pollinator:
Pollination
-
Emasculated plants produced 1.3 times the number of seeds produced by plants experiencing natural self-pollination.
-
There seems to be no mechanism to limit self-pollination, and cleistogamous flowers have been reported in cultivated specimens of coralberry.
-
Self-pollination in these strains was found to be controlled by duplicate, recessive genes.
-
Perfect flowers are protandrous, hence the stigmas open after anthesis, which reduces the probability of autogamous self-pollination.
-
This result is contrary to our hypothesis that the pollination-dependent detrimental fitness effects of clipping were caused by increased self-pollination in damaged plants.
-
This is sometimes referred to as self-pollination, but this is not synonymous with autogamy.
Pollination
-
Unless pollen is transported to another plant, geitonogamous self-pollinations therefore become more likely when plants are visited.
-
Despite being a self-compatible species, self-pollination is rare.
-
Geitonogamy can be due to self-pollination between flowers on the same branch, different flowering branches of the same plant, or different ramets of the same clonal genet.
-
Relative to self-pollination, outcross pollination results in greater proportion of flowers setting fruit, and greater proportion of ovules yielding seeds per fruit.
-
Self-pollination allows for distinct races to develop and several sub-species of annual knawel have been recognised, however their status in Ireland has not been investigated.
-
Treatment B was conducted to examine autonomous self-pollination by enclosing intact flowers, before anthesis, in small plastic bags.
-
While self-sterile plants are incapable of fertilization by self-pollination, genetically different individual plants of the same variety can be fertilized by cross-pollination (Figure 6.9).
5. How plants live and grow
-
None of these species set seed through agamospermy or autonomous self-pollination; therefore they depend entirely on pollinating agents for their reproduction.
-
As for calculation of the selfing rate, self-pollination was with pollen from other flowers of the same plant.
-
In self-pollination, the flower is monoclinous and the stigma receives pollen from the anthers of the same flower.
-
Besides, the cone was probably not exposed to pollen of other lacebarks and the seeds were probably empty or defective, as pines don't do self-pollination well.
-
Other examples of self-pollination are when a monoecious plant such as a squash or a plant with perfect flowers, like sesame, okra, or tomatoes, pollinates its own flowers, often with help from insects (Figures 6.4 and 6.5).
5. How plants live and grow
-
In addition, 62% of the flowers on these plants were cleistogamous indicating a high level of self-pollination.
-
Homogamy The condition in flowers in which the anthers and stigmas ripen at the same time, so encouraging self-pollination.
