| As for calculation of the selfing rate, self-pollination was with pollen from other flowers of the same plant. |
|
| Emasculated plants produced 1.3 times the number of seeds produced by plants experiencing natural self-pollination. |
|
| Treatment B was conducted to examine autonomous self-pollination by enclosing intact flowers, before anthesis, in small plastic bags. |
|
| Perfect flowers are protandrous, hence the stigmas open after anthesis, which reduces the probability of autogamous self-pollination. |
|
| Its flowering period is average and its self-pollination usually guarantees the fruit. |
|
| Consequently, an increase in autogamous self-pollination may be achieved with little reduction of outcrossed male fitness. |
|
| For self-pollination experiments bagged flowers without emasculation were manually pollinated with the same pollen. |
|
| When self-pollination occured, Darwin soon found a large, and unexpected, effect upon the next generation. |
|
| Not surprisingly, many species of plants have developed mechanisms that prevent self-pollination. |
|
| 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. |
|
| All these observations suggest that Maca reproduces predominantly by self-pollination. |
|
| If the pollen comes from the same flower or from a flower on the same tree this is called self-pollination. |
|
| Apart from these adaptations to limit self-pollination, plants generally produce more fruit following cross-pollination. |
|
| Continued self-pollination in successive generations leads to inbreeding, meaning a narrowing of genetic variation. |
|
| There seems to be no mechanism to limit self-pollination, and cleistogamous flowers have been reported in cultivated specimens of coralberry. |
|
| In self-pollination, the flower is monoclinous and the stigma receives pollen from the anthers of the same flower. |
|
| 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. |
|
| Plants from the Grahamstown population were incapable of autonomous self-pollination but pollinator-mediated self-pollination does occur. |
|
| 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. |
|
| The breeding system of T. sinense is mixed with self-pollination and out-crossing, with no indication of agamospermy. |
|
|
|
| This may be the reason why in many plants form or function of the flowers makes self-pollination difficult or impossible, thus favouring cross-pollination. |
|
| You can stimulate the self-pollination by shaking the plant gently every few days, holding the stem at the middle of the plant with the thumb and forefinger. |
|
| In bad weather the flower stays closed without any negative influence on the development of the seeds and it seems that self-pollination is common. |
|
| Relative to self-pollination, outcross pollination results in greater proportion of flowers setting fruit, and greater proportion of ovules yielding seeds per fruit. |
|
| Flowers are adapted to outcrossing, but plants appear to be self-compatible, and self-pollination probably occurs at high levels in small populations. |
|
| However, the species Eulophia foliosa has adaptation in the cap anther that prevents self-pollination by elaterid beetles, favoring crossed pollination. |
|
| Self-pollination in these strains was found to be controlled by duplicate, recessive genes. |
|
| 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. |
