There are many different kinds of PGRs. Some are general in function while others are very specific; e.g. shortening internode lengths in plant stems.

I've known ethylene as a means of accelerating ripening in fruit and never read about its use as a bloom stimulant -- probably due to my choice of literature.

Richard i can find instances of its use as a bloom stimulant on pineapple and a few other plants nothing on musa at all from what I read it can actually retard blooming in some plants there seems to be no -specific research on bananas other than as a ripening agent but from experience it does work well on pineapple as a bloom inducer in my area
time to bloom went from 36 to around 30 months plants spent summers on my deck and winters in the house fruit was of normal size but somewhat lacking in flavor
some info here much of it above my pay grade

a little more info this time on acetylene kinda vague but I will keep digging
and I have it on hand I have several young velutinas in the green house when the get a little bigger I may bag one gas it and compare the difference

In atomic absorption flame spectroscopy, acetylene is combined with high-purity synthetic air or nitrous oxide as a fuel for the flame.

Beyond its obvious value as a fuel gas, acetylene has many other less-well-known applications. It is used to produce certain plastics and chemicals for instance. It also plays a role in organic synthesis (laboratory work) and chemical synthesis. In plant cultivation, it improves the forming of new flowers.It is also used as a carbon source in molecular manufacturing, in calibration gases for the gas, oil and chemical industries and in lung testing gases.

Acetylene is manufactured commercially by reacting calcium carbide and water. It is also a by-product of ethylene production.

The results obtained in the elaborate
experiments with acetylene gas on plant
life at the Cornell University, as set forth
in a paper by Professor John Craig
(writes the "Acetylene Journal"), Chi

the close approximation of acetylene 1l

The sun, as everyone knows, stands for
life and development.in plant culture. It
is the chief element upon which the gar

and in abundance by agetylene, he at

benefit from acetylene was found not

I think you have a very sharp machete but you're cutting the wrong forest.

I believe it is within your means to grow specific cultivars from pups in the springtime and then overwinter them to produce fruit in the following year. For heaven's sake, there are members here in Little Rock Arkansas that do this.

If instead you wish to pursue the poorly charted research topic of accelerating banana fruiting with profitable results in non-tropical environments then I refer you to Gabe15. As of this post, I am unsubscribed from this thread.

Well Richard, I'll have you know that shortening the time to flowering in bananas would be an extremely useful tool in breeding programs where fruit quality and yield are not at all important, but making as many crosses as quick as possible is extremely important, not just logistically, but also in regards to funding and turn around time. To my knowledge, nothing has been published on being able to force bananas to bloom, and I've spent time looking and asking my breeder colleagues, but if you have found something that really does work, it would generate quite a lot of interest. You don't have any information at all on what the product was?

Matheson Ethylene gas ultra high purity LOT of 2 cylinders / bottles .25 lb each | eBay
When I harvest a late half filled bunch I hang it up just like normal and i slip a big black trash bag over the whole bunch. Donít seal it. Just leave a hole on top for air to flow. I throw fruit in the bag. Apples, wild persimmons, anything that puts out ethylene gas. In 2-3 weeks they are yellow!

I also will cut a hand at a time and place them in a paper bag with an apple or 2. It works and itís way cheaper and safer than buying the eBay stuff!

These unfilled bunches dry up in the middle FAST! Some like Orinoco will turn black before yellow if you donít force ripening. The key is to ripen them ASAP after picking them!

You could always do like they do in India! Take the immature bananas and force ripen them ASAP. Afterwards peel them and dehydrate/sun dry. I plan on trying some this year.

you can also use calcium carbide available on ebay for less than 20 bucks gives off acetylene gas on contact with moisture witch will also force ripening

Wow thank you. I will check that out! Do you know how much it takes?

a small amount in a damp cloth bag should do it stuff looks like gravel 1 or 2 small pices would be enough for a bunch
