In the process of growing hemp, even if we provide suitable growth conditions, hemp will occasionally show some special traits,cannabis gene mutation.
These special traits have nothing to do with the environment and are caused by genetic material variation, so-called genetic variation.Common mutation phenomena are:
Gene mutation 1:Three-leaf seedlings
Cannabis is a dicot plant. Cotyledons refer to the first two leaves of cannabis. These two leaves are one of the early structures contained in cannabis seeds. These two leaves can carry out photosynthesis with a very low intensity, but their main function is to store nutrients and a small amount of water. They are the earliest driving nutrients for the seeds. They start to turn yellow after the plant enters the seedling stage. Generally, it starts after the growth period. Will wither and fall. After germinating many cannabis seeds, I believe that the size of the cotyledon is not necessarily related to the growth rate. From my past experience, the smaller the cotyledon, the higher the vitality of cannabis.
There are exceptions, as individual cannabis seeds will contain three cotyledons. These three leaves will form three crevices, and three true marijuana leaves will emerge from these three crevices, that is, three primary true leaves. I don’t think the size and number of cotyledons will directly affect the growth rate of plants, but true leaves will. The three true leaves greatly accelerate the growth of the cannabis plant.
In the subsequent growth, marijuana will return to its normal state, and two nodes corresponding to the positions will be generated in each node, becoming new branches and leaves instead of three nodes.
Gene mutation 2: Twin seeds
In this cannabis gene mutation case, you will definitely harvest a lot. There are two cannabis embryos in one seed, and two cannabis plants will grow. This kind of situation is relatively common, probably more than 1 out of every 50 this kind of situation will happen.
This kind of seed is definitely the fastest to germinate. I think this is because two embryos are squeezed in one space. The total amount of growth hormone is larger than that of ordinary seeds. It will be concentrated at a certain point to promote rapid rooting of an embryo.
The twin seeds may not be visible when they germinate, but become obvious after they enter the seedling stage. Two seedlings emerged from the soil.
Or the fast-growing individual takes the slow-growing individual out of the soil entirely. Individuals with slow development may also adhere to the cotyledons of individuals with fast development.
Gene mutation 3: Two-color leaves
This is a mutation of the stem veins, which occurs in the veins, causing the same leaf to differentiate between two colors along the veins.
It may also occur on the branches, so that the leaves growing on the same branch node can differentiate into two colors.
If it occurs on the main stem, it will cause the overall color of the cannabis plant to differentiate. (This marijuana plant is half purple and half green)
The symptoms of tobacco mosaic virus are similar to this mutation, but tobacco mosaic virus is harmful, and the discoloration is uneven, and the boundaries are not obvious.
Gene mutation 4: Abnormal leaf shape
Abnormal leaves are the most direct manifestation of marijuana discomfort, but healthy marijuana also has a very low possibility of this situation.
Gene mutation 5: Abnormal number of leaves
This kind of cannabis gene mutation is very common, and cannabis will basically have this kind of mutation in an environment with excessive light intensity or excessive drought. The true leaves of marijuana leaves that grow after midnight will have three leaves, and the number of true leaves will gradually increase, increasing to five and seven, and finally staying at seven leaves.
Mutated marijuana will grow 4 marijuana leaves at the branch node
Grow multiple leaves
Keep most nodes to grow 3 leaves
This variation is generally caused by the unsuitable planting environment, which is unfavorable for the growth and development of hemp.
6: Node mutation
Pruning marijuana is one of the effective means to increase production. We usually prune the main stem of marijuana and also trim the side branches of marijuana. The purpose is to distribute auxin to where we need it. For the introduction of auxin, please see Weed Grow Lesson16:An effective way to increase the production of indoor cannabis-starting from gardening skills
It is also because of the relationship of auxin that there will be transformational variation between stems and branches and leaf veins at the pruning node.
The occurrence of similar mutations indicates that hemp itself is extremely vigorous and has good healing ability. It also indicates that the grower provides the most suitable growth environment for hemp, and that the skilled grower may encounter this kind of mutation.
This is the tip of the hemp we are going to trim.
We are here to trim the top of the hemp.
The trimmed marijuana will secrete fluid to seal the wound, just like a blood scar. But in very rare cases, this marijuana strain is too vigorous and does not realize that he is injured and continues to grow.
Because auxin will accumulate at the top, and high concentrations of auxin will preferentially stimulate stem cells to differentiate into leaves, so the pruned stems grow into branches and leaves.
It is also because of the same situation, in the case of trimming the side branches, the branches and leaf veins also have a very low possibility of differentiation into stems.
When marijuana grows, the more stems and branches, the better. If the main stem becomes a branch, the yield will be greatly reduced.
7: Calyxes grow at the nodes of leaf veins and branches
Rare but very valuable variation. Cannabis flowers generally only bloom at the nodes of the branches and stems, so when we harvest cannabis, hemp leaves and branches can only be discarded or used for other deep processing. The value they bring is low, but they cannot be used during the flowering period of cannabis. be lacked.
Once calyxes grow on the leaves, these calyxes can absorb the nutrients of the leaves and branches, allowing more nutrients and energy to be transformed into value.
Female, THC-filled female calyxes grow at the leaf nodes. Once this mutation spreads across your cannabis, the amount of flower buds you can harvest will double.
This is a male calyx that grows at the node. If you can have both male and female plants of this kind of mutation, then try your best to cultivate their seeds. When this trait is stable enough to be reflected in every subsequent cannabis plant, then you are the king of the cannabis world!
This variation makes hemp like vines such as creeper and grapevine, its branches become soft and will grow downward and creep on the ground. The branches and trunks that crawl on the ground will root when they touch the soil. If there is a wall or bracket next to it, it will climb up along the strong and bracket. The production of cannabis with this variant trait will be greatly improved.
9: Underwater cannabis
Interesting cannabis gene mutation: the bottom of the Chilean coastline, fishermen discovered a kind of marijuana that grows underwater. This is no longer a mutation. These mutations have stabilized and become stable plant traits. This breed is named fishermen’s friend. I think the research and development value of this variety is extremely high. I crossed it with those famous varieties, and tried to breed cannabis that is tall, dense, high in THC and can grow underwater. The concealment of this new variety will create incalculable value in countries where cannabis is illegal. Imagine an underwater, odorless giant cannabis planting base that the government does not understand… Even if such varieties cannot be cultivated in a short period of time, hybridization can strengthen the moisture tolerance of cannabis and improve the photosynthetic ability of cannabis.
Polyploidy cannabis gene mutation means that the genetic material in the cell is more than normal. It is reflected in humans such as Down syndrome, intersex, super healing power, cancer, multiple organs, and so on. Polyploidy is a super mutation that can evolve a species or kill an individual. Its research value is immeasurable and hard to predict. A small result may change the entire world.
Reflected in cannabis, this cannabis plant is extremely large, with many leaves, stems, and flower buds. If you can encounter this kind of mutation, you must use it for breeding.
In Darwin’s “Theory of Evolution”, mutation is the inevitability of biological reproduction, and nature will choose stronger mutants to survive and reproduce, so that organisms continue to evolve.
In the process of growing hemp, if there are beneficial mutations, you can try to cultivate new varieties through it to achieve unpredictable value.
