nen888 said:^..hey cave paintings, it is very interesting..
i don't quite have the time to cover all this sort of stuff right now, but there has been a lot of work done in biology on chemical signalling between plants..this can be via roots/soil, or as gaseous release into the air, absorbed through foilage..while plants do not have anything like animal receptors/neurons, they are none the less able to transmit signals to eachother..a wide range of chemicals can be both released and absorbed through leaves..
the level of information contained in these signals is not understood..
i will dig out a great plant biology book i have somewhere when i can, which has some good references..

[pre publication abstract of Chemical Signaling between Plants and Plant-Pathogenic BacteriaStudies of chemical signaling between plants and bacteria in the past have been largely confined to two models: (a) the rhizobial-legume symbiotic association and (b) pathogenesis between agrobacteria and their host plants. Recent studies are beginning to provide evidence that several plant-associated bacteria undergo chemical signaling with the plant host via low molecular weight compounds. Plant-produced compounds interact with bacterial regulatory proteins that affect gene expression.
technically a pheromone is only a chemical signal that is used between two members of the same species. If it’s a signal between members of different species it’s called an allochemical (even if it’s the exact same signal being used for a different purpose). These words don’t refer to different types or structures of molecules, only to their function. Allochemicals are broken down in to functional groups of allomones, kairomones, and synomones,
..i think you are right here..keeping an acacia in a smaller pot for longer periods will retard it's root growth rates and hence overall growth rates..if the roots sense greater depth they'll head down..What I am noticing is that the pot size - even for seedlings and small plants - seems to influence the growth rates .
Shane, A. Burkittii grows wild in South Aus. Have you tried that ?shanedudddy2 said:Anyone had any first hand success with Acacia Pycnantha?
Do people think I should attempt to find some and try an extraction?
Have tried so many failed extractions on local sources (Cyclops, Victoriae, Phalaris grass) that I am losing faith
Trying to find anything which will result in spice (that is within an hour or so drive) so I do not have to order online....but alas, my location seems to be terrible :/.
Any help would be most helpful.
..actually the top tryptamine-acacia state in aus seems to be becoming Queensland, if you look carefully at the species..a lot there turned up lately..I wish I lived in Vic, NSW or WA haha.
