Re: [Aroid-l] gGbberellic acid and inflorescence-Marek

From: "Marek Argent" <abri1973 at wp.pl> on 2009.08.07 at 02:19:22(19652) Hello Vincent et al, Yes, tubers and rhizomes are forms of stems not roots. People often talking about Amorphophallus say "stem pattern". This is not a stem, but a petiole. The green bodies of Lemnoideae are also modified stems - these plants have no leaves. And everybody knows that a spathe is not a "petal" or "flower", it is a leaf. Well, we are interested in the most strange plant family, and we're proud of this :) Marek HTML +More ----- Original Message ----- From: E.Vincent Morano To: Discussion of aroids Sent: Wednesday, August 05, 2009 9:13 AM Subject: Re: [Aroid-l] gGbberellic acid and inflorescence-Marek You are most probably correct about those plants being treated with ga3. As I was mention ing to another group member the plant may look nice and have flowers which is good for sales but at the end of the season, you will be left with a tiny tuber or no tuber at all. Which is also good for sales because your plant dies then you go buy another. Some information I was reading said that Zantedeschia bloom well with GA3. But I would think they would die at the end of the season or very soo as has been your experience :-) Thanks for telling me that a tuber is a form of a stem. I did not know that. And that may be part of the reason why ga3 can damage them. GA3 will cause main stems in plants to grow very tall. Obviously a tuber trying to grow tall will not work. Ive got no proof of this but the reasoning sounds sound to me. I refuse to participate in the in the recession. --- On Sun, 8/2/09, Marek Argent wrote: From: Marek Argent Subject: Re: [Aroid-l] gGbberellic acid and inflorescence production To: "Discussion of aroids" Date: Sunday, August 2, 2009, 11:32 AM Hello, Now I think I know why all Zantedeschia plants bought in pots in florist shops with many inflorescences died shortly after blooming. These pot plants must have been treated with GA3, they had more inflorescences than leaves, just to be a decoration for a few weeks. They had a lot of flowers, but no tubers, when the overground parts withered there was nothing in the pots except the peat. Zantedeschias I buy as garden plants with huge tubers behave differently. They produce one or a few inflorescences during summer and their tubers grow and divide. Thanks for this info, I haven't known this Marek P.S. A tuber is not a form of a root, but a form of stem (corm). ----- Original Messag From: E.Vincent Morano To: Discussion of aroids Sent: Saturday, August 01, 2009 12:34 AM Subject: Re: [Aroid-l] gGbberellic acid and inflorescence production Use caution with this if you care to experiment. GA3 retards root growth and will kill your tubers/rhizomes if it comes in contact with them. Do not use on amorphophallus unless its a variety that can grow a leaf and an inflorescence at the same time but dot expect much tuber growth as GA3 retards that also because is a form of a root. I've been using plant growth hormones for years. If you want to noticeably increase tuber growth then wait until the tuber has formed a leaf and the leaf is fully open and established. Then pour a 100-150ppm solution at the base of the plant avoiding the leaf,a higher ppm is not better, it will cause the plant to do different things. Just do this one time during the season and apply high phosphate or bone meal fertilizer. Keep in a hot and humid shaded greenhouse for optimal results. Using this method, I made a 2lb konjac grow into a 7lb monster in one season. The next year it gave me a perfect flower of specimen quality. Which Ive posted pictures of here in the past. This year Im doing this too all my tubers --- On Fri, 7/31/09, ExoticRainforest wrote: From: ExoticRainforest Subject: Re: [Aroid-l] gGbberellic acid and inflorescence production To: "Discussion of aroids" Date: Friday, July 31, 2009, 9:34 AM Thanks Marc!
