(1) This eliminates the possibility of self-pollination.

(2) They were maintained by normal self-pollination.

(3) Delayed self-pollination by curvature of stigma-lobes occurs in flowers of Kosteletzkya virginica, when pollinators are scarce or absent.

(4) It is a mechanism that helps prevent self-pollination and is most common among wind-pollinated and unspecialized insect-pollinated flowers, as in figwort.

(5) self-pollination , in general, produces lower percentages of seeds than controlled cross-pollination.

(6) The main reason of sterile under the self-pollination is the abnormality of the meiosis of pollen mother cells in tetraploid and the abortion of all pollens.

(7) Protogyny in M. grandiflora lies in a mechanism that determines the anther dehiscence stage, thus reducing self-pollination and interference between pollen and stigmas.

(8) With flowering plants with only a small part of the self-pollination, the transfer of its pollen is usually dependent on certain pollinators.

(9) The pollination is intra-population cross pollination but still belongs to generic self-pollination.

(10) Dichogamy The condition in which the anthers and stigmas mature at different times thus helping prevent self-pollination. Compare homogamy. See protandry; protogyny.

(11) In hermaphrodite and monoecious species, there is the potential for self-pollination leading to self-fertilization (selfing) unless there is a mechanism to avoid it.

(12) In protogyny and protandry there may be overlap in function between the sexes allowing for self-pollination if cross-pollination fails.

(13) The reason for the lower rate of fruit set by self-pollination and the problems which should be considered in the selection of pollinizer were also discussed.

(14) Homogamy The condition in flowers in which the anthers and stigmas ripen at the same time, so encouraging self-pollination.

(15) We used gas chromatography to study the quantity of IAA and ABA in pear young fruits of different varieties from self-pollination to first physiological fruit-falling period.

(16) Doe to its exceeding sterility, the mutation was maintained by heterozygotes, and it was also inherited stably after five generations of self-pollination.

(17) The new cabbage variety, Ninggan 1 is bred and selected by Xijie Seed Control Station through self-pollination of one mutant plant of the native cabbage variety.

(18) Seed set could be found out both in cross and self-pollination(different individuals within one cultivar ) plants, while 1000-seed weight was lower in self pollination.

(19) Until now, the mechanism of stigma closure and the hypotheses of avoiding self-pollination have been still uncertain.
