eted production of Reynoutria bohemica for pharmaceutical use. In a faah inhibitor well established knotweed stand in Loughborough, UK, reported almost 16 t ha of belowground biomass for R. japonica within the upper 25 cm with the soil layer. Our expectation is that extensive developing of far more productive species of R. bohemica on low fertile soils with no irrigation would produce a biomass of up to 10 t ha and would contain 80 kg of stilbenes. In the pot experiment, we observed an interesting interaction between the two primary aspects, the substrate along with the presence of melilot, which affected the production of resveratrol and its derivatives and emodin. Figs. 4 and 5 show that melilot elevated the concentration of resveratrol derivatives and emodin in plants grown on low nutrient substrates.
Generally, the effect of melilot appeared to be far more pronounced than the faah inhibitor effect with the substrates. This was revealed by smoothing the extreme values detected for the levels of resveratrol, its derivatives and those of emodin. We discovered that a large amount of biomass was created on compost with a high concentration of phosphorus as well as a low concentration of nitrogen , giving really low average N:P ratio . This suggests that the growth limiting nutrient in compost is nitrogen, not phosphorus. This can be in accordance using the evidence brought by indicating that N limitation may well occur when the N:P ratio is as high as 5.8. On the other hand, the nitrogen and phosphorus contents of all of the other substrates were significantly reduced and biomass values of knotweed plants grown on these substrates were reduced and had reduced phosphorus values but equivalent nitrogen values as the plants grown on compost .
The concentration of nitrogen was substantially higher within the presence of melilot, whilst the concentration of phosphorus decreased . This suggests that on clay and loess, phosphorus limits or co limits the growth of knotweed and that knotweed accumulates nitrogen but not phosphorus. The limitation of phosphorus reported by was on account of a N:P ratio greater small molecule libraries than 16, whilst in this effect was on account of a N:P ratio greater than 20. We present the following explanation for the low nitrogen fixation observed only on compost. Nitrogenase is recognized to be sensitive to oxygen. Oxygen free of charge areas within the plant roots are hence developed by the binding of oxygen to haemoglobin, which ensures anaerobic conditions important for nitrogen fixation http: www.

Reduced nitrogen fixation is hence expected in compost in comparison to clayish substrates. Indeed, our data from the second year with the NSCLC pot experiment showed huge quantities of nitrogen accumulated by melilot on low nutrient clay and loess substrates but not on compost . This obtaining agrees well with field observations that melilot grows well on heavy, clayish soils but not on organic substrates. In contrast to nitrogen, phosphorus was predominantly taken up from soil substrates. Knotweed deposited surplus amounts of phosphorus in rhizomes, specially when plants were grown on high phosphorus compost.
A synthesis of our data on plant biomass, resveratrol and its derivatives, emodin, nitrogen and phosphorus, small molecule libraries along with the relationships between these variables, are shown in Fig. 11. Regardless of regardless of whether or not melilot was present, the biomass of roots and rhizomes was positively correlated with phosphorus content and negatively correlated with nitrogen content. Nitrogen content was negatively correlated with phosphorus content. The phosphorus content faah inhibitor with the plants was very positively correlated using the phosphorus content with the substrate. Nonetheless, the total nitrogen content with the substrate was not correlated using the nitrogen content of knotweed rhizomes and roots . In the absence of melilot, there were no relationships between either phosphorus or nitrogen and resveratrol or resveratrol derivatives.
There was, nonetheless, a negative correlation between phosphorus and emodin as well as a positive correlation between nitrogen and emodin . The presence of melilot elevated the concentration of resveratrol and or resveratrol derivatives , but did not enhance the concentration of phosphorus in knotweed grown on low phosphorus substrates . These resulted small molecule libraries in a negative relationship between phosphorus and resveratrol and or resveratrol derivatives. On the other hand, knotweed plants grown on a high phosphorus substrate exhibited a high phosphorus content but low contents of resveratrol and or resveratrol derivatives. The presence of melilot also revealed a positive relationship between nitrogen and resveratrol or resveratrol derivatives due to the fact it elevated both nitrogen content along with the content of resveratrol or resveratrol derivatives . Moreover, we observed a substantial relationship between melilot biomass in 2006 and nitrogen content within the rhizomes and roots of knotweed in 2007 . Also, there was a difference in knotweed root and r
