Horticulture Research Videos ala Cornell

Cornell has published a variety of interesting research “posterboards” on YouTube. General horticulture topics (if you enjoy the science and experimentation aspects of growth).

Tessa Pocock: Light Matters - Sensing and Signaling in Plants

  • Suggests spectral phase for PWM driven LEDs matters. E.g. having out-of-phase LEDs across the action spectra reduces growth (contributing DLI does not change).
  • Suggests that differences in spectral peaks between LED vendors makes a difference (36nm difference in Blue shows significant difference in growth).
  • Discusses activation times in the action spectra.
  • Discusses balance between PS I and PS II action spectra.
  • Anthrocyanin production relation to spectra (purples).

Chlorophyll fluorescence as a tool for biofeedback control of photosynthetic lighting

  • Has discussion on plant protection mechanism against excess light. Non-photochemical quenching.
  • Discusses measurement of quantum yield (efficiency, healthy vs damaged leaves, etc).
  • Discusses electron transport rate as related to quenching and PS II efficiency.
  • Optimization of PPF (stable electron transport rate).
  • Suggests quantum yield (efficiency) decreases as light intensity increases.
  • Demonstrates damage due to excessive light intensity. Photoinhibition via B1 protein. Rate of repair.
  • Emerson effect explanation. Effect of far red on quantum yield.

And many more here: Cornell SIPS

great stuff! How long will it be until cannabis takes its place among these studies? I’m sure we’ll eventually see dozens of different cannabis flowering studies.

Yes, as the stigma and the threat of grant cuts decrease. Cornell, apparently, has three or four (rather recent) plots explicitly for Hemp research up and running. There should be some use-able research from them in the coming years.

See the resource section of that report for other universities engaged in similar research. All targeting hemp at this point.

Massachusetts created a special research license to foster research within the state, it will be interesting to see if any school jumps on the opportunity. We don’t have anything like the Cornell Ag. school in this state though, poor Cornell could be waiting a while to experiment with actual high-THC cannabis.

Maybe someone like Essex Aggy will jump on it.

Enrollment would shoot up if they offered a cannabis curriculum! No doubt.

Interesting. Perhaps that organization that has those Master Growers would be interested. Can’t remember the name of them. They use to be government funded but are now independent in MA. Can anyone think of their name?

And, who knows, there could be some off-the-books research going on as well.

We have Professor Lyle Craker at UMass - a hero of cannabis reform. I wonder if the state license is enough to do research or if schools will have to wait for federal permission as well? A private school should be able to proceed under state regulation. Here is the licence reg - annual fee is only $1,000 - pretty funny, they can’t sell the weed, not hard to imagine where it’s going to go:

(6) Marijuana Research Facility.
(a) A Marijuana Research Facility may cultivate, purchase or otherwise acquire marijuana for the purpose of conducting research regarding marijuana products.
(b) A research facility may be an academic institution, nonprofit corporation or domestic corporation or entity authorized to do business in the Commonwealth.
© Any research involving humans must be authorized by an Institutional Review Board.
(d) A research facility may not sell marijuana cultivated under its research license.
(e) All research regarding marijuana must be conducted by individuals 21 years of age or
older.

@99PerCent: Haha, if it’s a high school I’m certain the students are way ahead of the curve!

Yes, I think that’s what I was thinking of. Thanks.

Private school love grant dollars, much of which will be federal. If they can manage to self-fund instead of the constant desire to build billion dollar dowries, that would be positive. They would, of course, generate patents which could be a double edged sword.

Awesome link. I know the University of Michigan has a medical cannabis degree they offer. It’s on campus tho. It’s medical plant science I believe.

Michigan should be a little out front on this one, along with Oregon, but I am not that in touch with it.

Seems to me, if you wanted to learn the craft of growing, the techniques would more than lend themselves to most of agriculture, including our friend.

I agree wholeheartedly. Imo you’d get more use out of a degree in sustainable agriculture or regenerative agriculture. But that may just be my bias opinion toward soil and the soil food web lol.

I have a buddy who studied just that in college, maybe at Rutgers??

He has one of the nicest grows, but keeps it very hush hush.

That’s understandable given the state of legalization country wide and the stigma of being a “pot farmer”.
