self-pollination Betydning & definition

Eksempler på self-pollination

• This means that pollen transferred within a patch contributes to geitonogamous self-pollination.

• The possibility of an increase in abortive self-pollination in small or isolated populations cannot be ruled out as seed set was not quantified.

• We also show that self-pollination can lead to self-fertilization because over 70% of inflorescences hand-pollinated with self-pollen set seeds.

• Thus, with limited self-pollination and mostly stable wind conditions, piassava appears to require the service of flower-visiting insects for pollen movement.

• Sporadically, in certain environments, the male and female flowers of different plants open at the same time, and since plantations consist of only one clone, self-pollination occurs.

• Photos of flowers, taken at 60-min intervals during the night, showed no indication of an adaptive self-pollination mechanism achieved through the movement of floral parts.

• The flowers are usually pollinated by moths (hence the common name of the plant), butterflies and bees (entomophily), but they are capable of automatic self-pollination.

• Hibiscus breeders do not preclude the possibility of self-pollination.
