Results Pot Experiment Dining table 1 provides a summary of the results of the pot experiment. The above-ground biomass of knotweed showed several important variations between Hedgehog inhibitor the substrates in 2006 and 2007. The greatest biomass was stated in plants developed on compost in both years. There is also a difference observed between plants grown on clay and clayCS in 2007. Similar results were obtained for knotweed developed with melilot. The development of melilot was endless in 2006, which resulted in competition between melilot and knotweed. The current presence of melilot notably decreased the biomass of knotweed developed on compost and loess. But, decreasing knotweed biomass was mentioned in most of the substrates. A substantial decrease of knotweed biomass in the presence of melilot was also noted in 2007 when melilot growth was restricted, but this was only seen for the two low nutrient substrates, clay and loess. There clearly was a substantial huge difference in the lateral division number of knotweed flowers between 2006 and 2007. Relatively large numbers of lateral branches were present in 2006, and these numbers decreased somewhat in 2007 to 5 and 9 in plants grown on compost in the absence and presence of melilot, respectively. Lymphatic system The variety of lateral branches were paid off further to 0 2 in plants grown on the other substrates. The belowground biomass of knotweed was only tested in 2007. Below-ground biomass was significantly lower in plants grown on clay, significantly higher in plants grown on clay enriched with nutrients, and was greatest in plants grown on compost. The biomass of plants grown on loess was intermediate between plants grown Celecoxib ic50 on clay and those grown on clay. The presence of melilot reduced the underground biomass of knotweed developed on clayC, clay, and loess. The percentage content of resveratrol in knotweed rhizomes and roots was higher in the presence of melilot in 2007, except in the event of knotweed developed on compost and clayC. Related but non significant trends were noticed in 2006. Generally, the greatest concentrations of resveratrol were present in plants grown on clayCS within the presence of melilot. The best levels were found in crops grown on loess without melilot in 2006. Piceid can be a glucoside of resveratrol. The content with this piceid was also somewhat higher in the presence of melilot for plants grown on clay and loess. Resveratrol and its derivatives, like the glycosidic and aglyconic stilbenes, piceid, piceatannol, resveratrol and astringin, were notably higher in plants grown in the existence of melilot on loess, clay and clayCS. When it comes to nitrogen production, the highest levels in rhizomes and knotweed roots were found when plants were grown on compost and on clayCS.
