Abstract
Effects of chitosan oligomers and polymer on in vitro development of perennialryegrass (Lolium perenne L.), red fescue (Festuca rubra L.), and Kentucky bluegrass(Poa pratensis L.) were studied to elucidate a possible differentiation between theeffects of chitosan depending on its chemical structure. The seed germination rate wasenhanced after the oligomer treatments. The oligomer mixture triggered leafelongation better than the polymer. However, the highest number of leaves was foundfrom L. perenne in the polymer's presence at 10 mg·L -1 in the medium. The maximumleaf length was reached in L. perenne after oligomeric chitosan treatment at 5 mg·L-1 .The plant's rhizogenic response was enhanced in P. pratensis but decreased in L.perenne and F. rubra after 2.5 mg·L-1 oligomeric chitosan treatment. However, the rootelongation was restricted in F. rubra and P. pratensis after chitosan treatments.Conversely, chitosan treatments augmented root elongation in L. perenne. This studysuggested that chitosan might be preferred to ensure better turf coverage in thesegrass species. However, constant- or over-treatment with chitosan could reduce rootgrowth and increase the plant's leaf elongation that might contribute to nutritionaldeficiency and increased mowing costs, respectively
