tion in biomass ? Limitation of plant production by nitrogen ? Low resveratrol, resveratrol derivatives and emodin production. The efficiency of nitrogen fixation was considerably correlated with the ratio of resveratrol to resveratrol glucoside. This indicates that knotweed CAL-101 contributed towards the energy cost of nitrogen fixation for melilot and that there's an exchange of organic substances among these two plant species. There appeared to be differences among 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 on the very same material CAL-101 as the soil in the field experiment , loess from nearby loess deposits and compost was that used for dump reclamation. The chemical composition on the substrates is shown in Table 2. Ten pots were filled with 7.25 kg of clay each and every and 2 l of one of the following substrates: loess ; compost , composed of a 1:1 mixture of widespread compost plus 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 items see http: www. symbiom.cz. A mixture of six mycorrhizal fungi species with at least 80,000 living propagules per litre in zeolit or spongilit was added to each and every pot, in addition to expanded clay enriched with natural fertilizer.
Conavit can be a completely natural slow nutrient releasing fertilizer composed of sea algae, humus substances, ground minerals and rocks, and can be a natural source of keratin. A quantity of Conavit corresponding Gefitinib to 160 kg ha was applied. Symbivit was added towards the Conavit treated pots on top on the bottom clay layer. The bottom layer of clay had a texture of larger lumps, when the overlying material was broken up into smaller particles. Twenty pots of each and every variant were prepared for a total of 100 pots. The pots were thoroughly wetted and kept in the greenhouse at 18 27 C. During the summer, the whole set was transferred outdoors towards the experimental garden and was kept moist making use of automatic drop irrigation as required.
Plants At the begin on the experiment, November VEGF 18, 2005, segments of R. bohemica rhizomes that had been pre cultivated in peat were very carefully prepared. Every pot received a segment of washed rhizome with a known fresh weight plus a known number 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 considerably among the variants. Roughly 40 added segments of these rhizomes were each and every inserted into a modest pot of perlite in an effort to create plantlets in case some of the plants in the experimental pots failed to grow. This proved to be an incredible advantage because some of the rhizomes, specifically those from the variant grown with Conavit, did not create any plantlets. This can be almost certainly due to 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 devoid of restriction, no matter which variety of substrate they were transplanted into. Following three months, the R. bohemica plants were effectively established and white melilot seeds Gefitinib were added to 10 out on the 20 pots of each and every variant. The capacity on the seeds to germinate was assessed prior to seeding and was found to be 57 based on the average from 10 Petri dishes, each and every with 25 seeds. You will find approximately 500 seeds in a single gram. Following the first season, the plants were harvested in September 2006. We measured CAL-101 twig numbers, lengths and dry masses of both Reynoutria and Mellilotus, and excised 100 mm segments on the new rhizomes, which formed alongside the pot wall, for chemical analyses.
The ramification on the branches was also taken into account; the lengths of all the main branches Gefitinib rising from the soil, also as the lengths of all of the side branches, were measured and evaluated. Fine roots were sampled, when knotweed roots were hand separated from the melilot roots, and both were stained and inspected for the presence of mycorrhiza. The experiment was terminated following the second season in September 2007. At the end on 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 making use of air and water pressure. These were then dried and ground for analysis. Melilot was allowed to grow devoid of restriction during the very first season, but plants were repeatedly cut during the second season to sustain a height of 30 cm.
