In pistachio trees due to the fact that the flowers are pistachio wholesale without petals and attractive for
Insects, especially bees, are not pollinated by wind
Takes. Lack of light air flow and rainy weather, unfavorable conditions
They form pollen grains for dispersion. Also strong winds and storms
Dries the stigma surface and rain causes the stigma surface to be washed away
It goes sticky. The period of acceptance of female stigma is about 2 to 3 days
Have reported that if there are suitable environmental conditions and supply of pollen
Suitable and sufficient, the nodule germinates, the pollen tube grows and enters the ovary
After combining with the egg cell, it forms the embryo. If pollen
Do not spray, the flowers will fall off and the fruits will be empty. Flowers fall
Non-pollinated plants usually within 3-4 weeks after full flowering stage
Done. The farthest effective distance between male and female pistachio trees where it blows
A gentle breeze found at least one live pollen on the female flower stigma
Is 20 meters. The right ratio of male and female pedestals in a garden is the most important
Factors influencing pistachio pollination and observing the ratio of one male tree per
All 8 female trees can provide enough pollen and the problem of shortage
Remove the pollen. Planting a row of male trees perpendicular to the prevailing wind path and in
The edge of the garden produces a good amount of pollen. In areas where cultivation and acquaintance
Extensive pistachio orchards with extensive operations and pistachios as well as wind
Suitable wind when the trees are flowering, the ratio of female to male trees, can be
Increased and the ratio of 20 to 25 female trees versus a suitable male tree
is. In areas where there is not enough pollen or environmental conditions prevent it
Pollination becomes natural, artificial pollination using pollen
It is done safely and safely. The best time for extra pollination is when
Most of the young flowers are in clusters. High increase in pollen
Stigmas may in some cases cause competition between pollen grains
Stigma and reduce female flower fertility.
