What is apical dominance in cannabis?

What is apical dominance in cannabis?

During apical dominance, the lateral buds are inhibited by the shoot apex, encouraging the plant to grow vertically and absorb more light for photosynthesis. Apical dominance. Lateral bud initiation. Development and elongation of the lateral bud as it becomes a branch.

Does LST break apical dominance?

LST + OGS = Apical Tuning™ When it comes to breaking Apical Dominance, The OG Spring™ (OGS) is a tool designed to direct plant training so that reactive measures, like HST, can be minimized or avoided completely.

Do you have to top with LST?

As these grow up, they can be topped and manipulated using LST. Important points to remember for LST include: LST should be started as soon as possible during the vegetative phase. Flowering phase can commence once all major branches are horizontal and level with each other.

What does the apical bud do?

Typically, the end of a shoot contains an apical bud, which is the location where shoot growth occurs. The apical bud produces a plant hormone, auxin, (IAA) that inhibits growth of the lateral buds further down on the stem towards the axillary bud.

What is apical pruning?

By removing the apex, pruning temporarily destroys apical dominance and stimulates the growth of lateral buds into shoots. Figure 4. Pruning stimulates lateral shoot growth close to the cut. Pruning also reduces the size of the above-ground portion of the plant in relation to the root system (Fig.

How long after topping can I LST?

Healthy plants usually take 2-3 days to recover from topping. After topping, do not remove the leaves from that node as these are needed to power growth of the branches from that node. Never top during flowering as it causes too much stress – which slows growth and inhibits yield.

What’s the difference between topping and Fimming?

Topping marijuana plants is a technique where you cut the central apex of the plant off to help encourage lateral growth. Fimming is a technique similar to topping, one that requires a cut near the top of the plant, on the central stem or apex. It is used as a slightly less traumatic technique on plants.

Which hormone has negative effect on apical dominance?

Auxin causes apical dominance and gibberellin causes internodal elongation. Cytokinin promotes the growth of lateral buds by suppressing the growth of apical bud.

How do you overcome apical dominance?

Presence of cytokinin in an area causes preferential movement of nutrients towards it. When applied to lateral buds, they help in their growth despite the presence of apical bud. They thus act antagonistically to auxin which promotes apical dominance. Therefore cytokinin can overcome apical dominance, caused by auxins.

What is apical dominance?

Apical dominance was first discovered in 1934 when botanists observed how the plant hormone auxin was transported through the plant’s phloem before being diffused into the lateral buds in order to regulate apical dominance. During apex removal, the plant normally undergoes four stages:

How does lateral growth work in cannabis?

Cannabis plants naturally grow with an apical dominance, meaning they will always produce one central cola with side branches. By applying L.S.T to Cannabis plants, the production of the growth hormone Auxin is cut short, allowing the growth energy to be converted into a lateral growth.

What is apical pruning and how does it work?

Apical pruning’s a simple process – cutting the upper and main plant stems to paralyze their growth and boost the growth and production of side and lower branches; main stem gets weaker, but more branched structure’s boosted – many productive, stronger, fatter side branches (two new branches per pruning).

Is low stress Cannabis Training better than topping?

Low stress cannabis training is an easy technique to master without any of the highly stressful effects associated with cutting off the growing tip of the cannabis plant (‘topping’). If you are new to cannabis growing, or if you are risk averse, then low stress training is definitely recommended vs topping.
