the fact something is peer-reviewed does not mean it supports your position. you have nothing but anecdotes. when confronted with lack of evidence, your response is to ask for evidence refuting your assertion.
"can you prove it isn't true", in other words.
Scwilly; Perhaps you can post some full studies supporting plant uptake of whole organic molecules. I'm interested.
I would be trying to get them to grow my favorite - the brandywine.

Schwilly the problem is lack of logic in the way you jump to conclusions.
That's why I was dismissive. We have no basis for discussio. Because we don't agree on the terms.
You referred to stories of buds getting sweeter from molasses and I have heard lots of ANECDOTAL evidence for that and I assume you have too.
The studies you posted simply DO NOT back up your claims, but are rather loosely related to the subject. I am not going to start a discourse on how not to jump to conclusions from reading scientific literature. Been there, done that, not productive. Its much easier to simply point out the erroneous conclusion for the benefit of other readers.
The links I posted support the existence of such a mechanism in certain other plants.
The uptake by roots from solution, and subsequent translocation to shoots in barley, of two series of non-ionised chemicals, O-methylcarbamoyloximes and substituted phenylureas, were measured, Uptake of the chemicals by roots was greater the more lipophilic the chemical, and fell to a lower limiting value for polar chemicals. Translocation to the shoots was a passive process, and was most efficient for compounds of intermediate polarity. Both processes had reached equilibrium within 24h of treatment. The reported behaviour of many pesticides in various plant species agrees with the derived relationships, but the detailed mechanisms of these processes are unknown.
n dealing with the passive transport of organic contaminants from soils to plants (including crops), a partition-limited model is proposed in which (i) the maximum (equilibrium) concentration of a contaminant in any location in the plant is determined by partition equilibrium with its concentration in the soil interstitial water, which in turn is determined essentially by the concentration in the soil organic matter (SOM) and (ii) the extent of approach to partition equilibrium, as measured by the ratio of the contaminant concentrations in plant water and soil interstitial water, αpt (≤ 1), depends on the transport rate of the contaminant in soil water into the plant and the volume of soil water solution that is required for the plant contaminant level to reach equilibrium with the external soil-water phase. Through reasonable estimates of plant organic-water compositions and of contaminant partition coefficients with various plant components, the model accounts for calculated values of αpt in several published crop-contamination studies, including near-equilibrium values (i.e., αpt 1) for relatively water-soluble contaminants and lower values for much less soluble contaminants; the differences are attributed to the much higher partition coefficients of the less soluble compounds between plant lipids and plant water, which necessitates much larger volumes of the plant water transport for achieving the equilibrium capacities. The model analysis indicates that for plants with high water contents the plant-water phase acts as the major reservoir for highly water-soluble contaminants. By contrast, the lipid in a plant, even at small amounts, is usually the major reservoir for highly water-insoluble contaminants.
no room for emotion in science.
