Thank you for your response. It was a very long report. I went through the whole article and the main thing I noticed was there were a lot of data gaps. I don’t know if there is any more information since then. As you noted, the analysis showed GA3 is not so toxic. However, that is quite a relative term, depends on the personal health of the consumers. Also, as you noted, it is permitted by OMRI.
There were two things that concern me from the report for the long term effects:
In short-term oral studies with rats, the critical effects were observed in kidneys and liver (increased
relative weight). The relevant short-term oral NOAEL is 680 mg/kg bw/d (90-day rat study; Auletta,
1990 in Hungary 2008, 2011).
Classification and proposed labelling with regard to toxicological data (Annex IIA, point 10)
peer review proposal
Substance classified (name) No classification is proposed. However, the
database is not suitable to assess adequately the
reproductive toxicity and carcinogenic potential.
As for growing jujube, I have one in an ~18 gallon container that I bought from Amstrong Garden a long time ago, so the name was lost. It had no fruit for a long time. Three years ago it had some small elongated fruits so I thought it was a Lang. Next year there was a small plant growing from the rootstock that was full of tiny and sour fruits that I eventually took out. The main tree was full of flowers but no fruit. Last summer, it was full of big, round and sweet fruits and I really don’t know what variety it is now. The only difference was I put in a new Pink Lady apple in container, which had fruits and flowers, about 10 ft away. I have a fuji apple in another section of the yard that has a lot of fruits every year, but didn’t help the jujube at all. We will see what happens this coming summer.
Thanks again for your help.
