Found this, was hoping to get some feedback from the super growers out there. https://www.sciencedaily.com/releases...0804212931.htm

Seems to me the article is more about cloning at the cellular level, rather than taking cuttings from a plant.

Mutations are a part of evolution... and marijuana is a pretty amazing plant in its ability to withstand time. Goes to figure that a plant that can produce both male & female flower parts, might also have the ability to alter itself generation to generation, in clone form & at the cellular level, but manifests in plant growth characteristics. Potential pain in the ass for us, but pretty cool of the plant itself.

Isn't this how UK Cheese supposedly came about... a mutated runt of a Skunk #1 clone that had been around for years & years & years in some dudes closet? Drifted to whatever it is now...???

great article...thanks for posting

very nice find! thank you!

The team report their findings in this week's Current Biology.
'Anyone who has ever taken a cutting from a parent plant and then grown a new plant from this tiny piece is actually harnessing the ability such organisms have to regenerate themselves,' said Professor Nicholas Harberd of Oxford University's Department of Plant Sciences, lead author of the paper. 'But sometimes regenerated plants are not identical, even if they come from the same parent. Our work reveals a cause of that visible variation.

I guess showing me that cloning won't produce similar growing plants and I'll trust you..I mean why clone if you don't want something predictable?

This does not apply to taking cuttings from Cannabis.

Cannabis plants, when propagated from clone or meristematic cuttings, do not show the genetic variation (ie somaclonal variation) being discussed in that paper.

The paper specifically discusses regenerants... regeneration is a term used to describe the process of plants going from callus (akin to stem cells, in plants- undifferentiated cells), and subsequent organogenesis into shoots.

This process brings plants from shoots, back down to groups of single cells, and multiplies the cells as callus. After specific treatment with cytokinin and auxin-like chemicals, the cells can be coaxed into forming shoots again. There is work going on currently in Cannabis to determine whether this process induces mutations, or somaclonal variation, as it does in some other species.

However, if the meristem is preserved, as it is when we take cuttings in drug cannabis, there is no genetic mutation and a clone is exactly that- a clone with identical rates of cellular respiration, and production of secondary compounds like terpenes and cannabinoids when compared with the donor or mother plant.

Hope that helps,

ahh... cytokinin, one of the auxin's i know and love !

[Chimera]

I hope you are kidding bigbag... cytokinins and auxins are not in the same family, and cytokinin is not an auxin. They are both plant hormones, but have different roles within the system. Perhaps I should have been more clear above and typed cytokinin-like and auxin-like molecules.

From plant-hormones.info:

Nature of Auxins
The term auxin is derived from the Greek word auxein which means to grow. Compounds are generally considered auxins if they can be characterized by their ability to induce cell elongation in stems and otherwise resemble indoleacetic acid (the first auxin isolated) in physiological activity. Auxins usually affect other processes in addition to cell elongation of stem cells but this characteristic is considered critical of all auxins and thus "helps" define the hormone (Arteca, 1996; Mauseth, 1991; Raven, 1992; Salisbury and Ross, 1992).

Nature of Cytokinins
Cytokinins are compounds with a structure resembling adenine which promote cell division and have other similar functions to kinetin. Kinetin was the first cytokinin discovered and so named because of the compounds ability to promote cytokinesis (cell division). Though it is a natural compound, It is not made in plants, and is therefore usually considered a "synthetic" cytokinin (meaning that the hormone is synthesized somewhere other than in a plant). The most common form of naturally occurring cytokinin in plants today is called zeatin which was isolated from corn (Zea mays).
