The remarkable flower avocado
Avocado Flowers A B. Introduction. The avocado flower behavior (Persea americana Mill.) It is remarkable that there is nothing quite similar to what is known in any other plant. The flower has both female and male organs, but not simultaneous. Each flower is feminine when first opens. That is, the mark will take pollen from other flowers avocado, but the stamens (male organs) do not shed pollen at this first opening.
The petals and sepals, like avocado, protecting delicate organs of sex and develop. Nectarines and layered secrete nectar that attracts bees. To obtain a fruit avocado, a bee (or other flying insect) must transfer pollen from one flower to the stigma different this first flower opening. The sperm from the pollen develops under the thin style to fertilize the female egg in the ovary, which then develops to ripe fruit.
The unique flow of avocado.The first or female step remains open only for 2 or 3 hours. The flower then closes and remains closed during the day and that night. The next day opens again. But now the position will no longer receive pollen. Instead, now the flower sheds pollen. That is, each female flower is in the first opening, the male in the second. Once opened several hours the second day, the flower closes again, this time forever. If it had been plastered with success in the first opening and if there are other proper conditions will evolve into a wonderful fruit.
The flowers type “A” and “B” of
Nature has created cross-pollination with avocado creating two kinds of varieties. The type “A” female morning of the first day and the man in the afternoon of the second day (when the weather is warm). The type “B” is the exact opposite: the female flowers are in the afternoon and the men the next morning. For a flower from each variety, the time will be as follows:
First day
Second day

Morning
Afternoon

Type” B ”

But with hundreds of flowers that open at both stages by the day, daily situation looks like this:

Avocado Flowers A B. Open flower and temperature are two flowering types behave clock accuracy only when the average temperature (minimum and maximum day night) is above 70 degrees F (21,1 C ). As temperatures fall, the daily openings linger and become irregular, so one tree can have flowers in both female and male stages simultaneously. This helps to explain how large pieces of a single variety sometimes bring heavy crops.
However, as the average temperature falls below about 70 F, flowers function less well. Below about 60 F (15,5 C), may be zero.
Current research
Currently efforts are under way to determine if the type “A” and “B” plants with plants will increase pollination and yield. For some early results of this study, see. “Avocado Flowers Key”
