Abstract


Jerusalem artichoke (Helianthus tuberosus L.) is herbaceous perennial plant rich in inulin and useful source of biomass. Due to its low agricultural requirements and high adaptability, it can provide very high biomass yields even on low quality sites. The plant is used in food industry, bio-fuel production, forage, pharmacy and nutrition. Its tubers accumulate approx. 10-20% of inulin in fresh weight. Currently, the use of the Helianthius tuberosus L. as a potential dietary strategy in patients affected by type 2 Diabetes is challenge. Moreover, deep understanding of the relationship between diet and composition of gut microbiota can bring the new insight in the treatment of inflammatory dependent diseases. The aim of this study was to examine an effect of plant growth retardant Chlorocholine Chloride (CCC) on the plants’ height of H. tuberosus and inulin content in the tubers. We examined in the field a procedure for its shoots reduction. Material for the experiment were bought in a Polish commercial company and 528 tubers were planted in field in the middle of April 2014. Then, half of them were sprayed with 0.75% retardant of CCC . Furthermore, every week for 12 following weeks, the plants’ heights were measured. After the vegetation was over, 6 tubers for each treatment were dug out and chemically analyzed for inulin content using High Pressure Size Exclusion Chromatography.

After first week of CCC use, 16% decrease of the heights plants was observed. Height of plants sprayed with CCC were significantly different comparing to Control. Weekly growth was significantly  slower in plants sprayed with CCC on first three weeks after applying retardant. Differences in plants height sustain to the end of measurements. Used retardant and its concentration did not affect the inulin content of the tubers.
