The resulting pollen is sticky and is carried by the wind. Only bees but moths attracted by the smell of nectar, transfer it from flower to flower. Although the avocado flowers bisexual, they are arranged so that it is not capable of self-pollination. As disclosed in anticipation of the pollen of a flower pistil (female phase), the anthers of a flower are not yet ripe for pollination. But the flower is arranged so that the next phase of flowering rose about a day. When he re-opens with ripe pollen (male phase), its anthers have withered, so there is only a single-pollinated flowers. In some varieties of avocado flowering phase of female accounts for the morning, the other side of sorts — for the evening. Men phases of these varieties also occur at different times of day. Therefore, when growing avocado plant near varieties with different types of flowering: from varieties for which the female phase of flowering occurs in the first half of the day, plant varieties, which at this time of day have male phase of flowering.
