tion in biomass ? Limitation of plant production by nitrogen ? Low resveratrol, resveratrol derivatives and emodin production. The efficiency of nitrogen fixation was substantially correlated with all the ratio of resveratrol HDAC Inhibitor to resveratrol glucoside. This indicates that knotweed contributed towards the energy price of nitrogen fixation for melilot and that there's an exchange of organic substances amongst these two plant species. There appeared to be differences amongst the substrates. Compost was revealed to have a low efficiency of N fixation and, at the same time, showed a greater proportion of resveratrol glucosides compared with its aglycones. The opposite was true for the clayish low nutrient substrates, clay and loess.
Clay of miocene origin was obtained from spoil banks that were made up from the identical material as the soil in the field experiment , loess from nearby loess deposits and compost was that applied for dump reclamation. The chemical composition from the substrates is shown in Table 2. Ten pots were filled HDAC Inhibitor with 7.25 kg of clay each and 2 l of one of the following substrates: loess ; compost , composed of a 1:1 mixture of widespread compost and also a cellulose rich paper mill by product called Lignocel ; or clay enriched with a slowrelease biofertilizer Conavit? ; or clay enriched with Conavit and 50 ml of arbuscularmycorrhizal product Symbivit? . For technical sheet and composition of both merchandise see http: www. symbiom.cz. A mixture of six mycorrhizal fungi species with a minimum of 80,000 living propagules per litre in zeolit or spongilit was added to each pot, along with expanded clay enriched with all-natural fertilizer.
Conavit is a totally all-natural slow nutrient releasing fertilizer composed of sea algae, humus substances, ground minerals and rocks, and is a all-natural source of keratin. A quantity of Conavit corresponding to 160 kg ha was applied. Symbivit was added towards the Conavit treated pots on top rated from the bottom clay layer. The bottom layer of clay had a Gemcitabine texture of larger lumps, while the overlying material was broken up into smaller particles. Twenty pots of each variant were prepared for a total of 100 pots. The pots were thoroughly wetted and kept in the greenhouse at 18 27 C. Throughout the summer, the whole set was transferred outdoors towards the experimental garden and was kept moist using automatic drop irrigation as needed.
Plants At the begin from the experiment, November 18, 2005, segments of R. bohemica rhizomes that had been pre cultivated in peat were cautiously prepared. Each pot received a segment of washed rhizome with HSP a recognized fresh weight and also a recognized quantity of buds. The average fresh weight of a segment was 3.3 g as well as the average bud number was 1.6. The bud numbers did not differ substantially amongst the variants. Roughly 40 further segments of these rhizomes were each inserted into a little pot of perlite in order to create plantlets in case a number of the plants in the experimental pots failed to grow. This proved to be a fantastic advantage due to the fact a number of the rhizomes, particularly those from the variant grown with Conavit, did not create any plantlets. This can be most likely resulting from the adverse effect of humic substances on the growth of fine roots.
The dormant rhizomes were later exchanged for mature plantlets from the perlite pots. The pre grown plantlets continued their growth with out restriction, regardless of which type of substrate they were transplanted Gemcitabine into. Right after three months, the R. bohemica plants were effectively established and white melilot seeds were added to 10 out from the 20 pots of each variant. The capability from the seeds to germinate was assessed prior to seeding and was identified to be 57 according to the average from 10 Petri dishes, each with 25 seeds. You can find roughly 500 seeds in one gram. Right after the first season, the plants were harvested in September 2006. We measured twig numbers, lengths and dry masses of both Reynoutria and Mellilotus, and excised 100 mm segments from the new rhizomes, which formed alongside the pot wall, for chemical analyses.
The ramification from the branches was also taken into account; the lengths of all of the major branches rising from the soil, HDAC Inhibitor as well as the lengths of all of the side branches, were measured and evaluated. Fine roots were sampled, while knotweed roots were hand separated from the melilot roots, and both were stained and inspected for the presence of mycorrhiza. The experiment was terminated soon after the second season in September 2007. At the end from the experiment, both the aboveground and belowground biomass were measured, the fine roots were sampled for mycorrhiza and larger roots and rhizomes were thoroughly washed using air and water pressure. These were then dried and ground for analysis. Melilot was allowed to grow with out restriction during the first season, but plants were repeatedly cut during the second season to sustain a height of 30 cm.
