Dear Shanthi:

For some reason I didn't get your original email asking about organic methods of forcing.  It would help if you could be more specific because what is acceptable to one organic group might not be acceptable to another.

You may know that ethylene is acceptable in both the U.S. and Europe for forcing of pineapple destined for organic markets.  On techniques, Alain Soler wrote an article for Pineapple News No. 13, page 27 on methods for forcing with ethylene on small farms.  In issue No. 16, page 6,  Van de Poel, Ceusters and De Proft reported on a zeothene that would adsorb ethylene and showed that it could be used to force pineapple.  The unanswered question is when the zeothene will be commercially available and whether it would be acceptable as an ethylene carrier for the forcing of organic pineapple.  Lastly, there was some discussion several years ago about the use of cold water or ice for the forcing of pineapple for the organic market.  Chin-Ho Lin and students have refined the technique and you can find his summary of the technique on page 31 of Pineapple News No. 16.  Chin-Ho was working with a "sensitive" cultivar of pineapple, i.e. one that was easy to force, so the technique should work similarly with 'Queen' but might pose a challenge with the more difficult to force 'Smooth Cayenne'.

I assume you know that carbide in contact with water produces acetylene, not ethylene.  However, if there is a natural source of carbide, it still might be acceptable as a forcing agent for pineapple.  I don't try to keep up with organic regulations but it is my impression that acetylene sourced from manufactured carbide is not approved for use in forcing pineapple destined for the organic market.

If the technique(s) for a small scale and friendly method of flower induction with ethylene referred to below are considerably different from those in Alain Soler's report, I would welcome a note or article about the technique(s) for inclusion in the next issue of Pineapple News.

With best regards,
Duane

Dear Shanthi,

We have been working on that and are using a smallscale friendly method of ethylene flower induction with farmer groups.  My email is robmoss AT waffco.org  i can put you in touch with out project coordinator who works on that issue.

Dear Duane,

 

I wonder if you would be able to help with information on organically acceptable methods for flower induction.

 

Best regards,

 

Shanthi
