Know how far the pollen of cannabis travel

Clara Gibson
Cannabis sativa is an annual herbaceous plant that belongs to the eastern Asian regions. But now, it has a cosmopolitan distribution since it's cultivated widely. They are an essential source of seed oil, industrial fiber, medicine as well as religious and spiritual mood elevator.

Why is cannabis cultivated?

While the cannabis plant is in the vegetative, it requires more than 12-13 hours of daylight to remain in the said phase. Seed dispersal occurs, and then the pollen travels far apart for fertilization. Cannabis is cultivated for the reason they have extensive usage in medicinal and commercial lives. The plant is used in making hempseed oil, which is used for cooking, lacquers, paints, lamps, as well as feeding the caged birds, animals. Psychoactive chemical compound found in cannabis is used for a medicinal recreational and spiritual purpose. They are used to preparing tea, the tincture, ointment, analgesic, sedative, and anti-inflammatory purposes. During the year 2018, a farm bill passed and legalized, which allowed the farming of industrial hemp.

While you maintain the 5-kilometer isolation

What is the nature of pollen grains, and how far can they travel?

The pollen of Cannabis is disseminated, and they can travel far wide in large amounts and distances. Some regulations happen to be concerned with the production of pedigreed seed. It is often seen that a considerable range has to be isolated so that the pollen can travel far. In countries like Europe and Canada, there is a minimum requirement of a 5-kilometer distance for the cannabis pollen to disperse and go. Studies have revealed that cannabis requires a three-week flowering period, and they travel a particular way abiding the wind.

While you maintain the 5-kilometer isolation distance, the required isolation area can be reduced by at least 58% while the pollen travels the opposite side. When weedy and other illegally cultivated plants are distributed widely, it makes the cannabis pollen difficult to move even that 5-kilometer distance. If you draw a curve, the distance traveled by the pollen grain reduces with the source. The more range it goes, the lesser is the potential pollen grains that have high-quality genes in it.

Thereby, the right genetic mix is

What is the outcome of pollen traveling so far?

The reason why pollen travels naturally by wind, insects, or other agents is that the ovaries have to fertilize in natural processes. The advantages of powder going far and wide are that they feed with various breeds of flowers and bear better variety.

Thereby, the right genetic mix is observed and it leads to improved variety. There is the boon of cross-pollination, i.e., when the pollen grains touch ovaries of different trees, it leads to better variety. In case when the pollen grains breed with the same trees, there is hardly any development of variety. Well, pollination can account for environmental pollution and allergy for certain people.

What are the primary agents that aid pollen grains travel?

Various factors aid the pollen to disperse, travel, and reach other plants. The most effective agent is the wind which aids pollination. When the trees are geographically isolated, they still have the advantage of cross-pollination as the direction of wind helps them. Variegated insects like butterflies and bees often help in carrying the pollen grain and fertilizing ovaries of other plants. Birds of several types are instrumental in taking pollen grains to different trees. Herbivorous animals can sometimes prove to be pollen carriers when they rest beside the trees, the chance to carry some pollen grains and help to reach other trees. The process is nothing but a boon for the better breed.

Cannabis is a kind of dioecious plants where male and female parts grow in different plants.

There are some monoecious varieties, but the other type is more prevalent. The pollination period is over two weeks, and a male flower can produce over 350,000 pollen grains. Bees are instrumental in collecting pollen grains, but they don't have hundred percent chances of pollination. However, improved varieties are obtained only when cross-pollination occurs, and it is evident to leave stretches of land isolated for the pollen grains to travel. Superior variety of crop yields when there is better cross breed and this is possible only when there are chances of efficient pollination and pollen grains travelling far in search of ovary.
