Abstract

The influence of polymer chitosan and itspartially hydrolyzed derivatives was studied through an invitro assay on different variables that characterize soybeannodulating process. In all cases, chitosans applied by meansof seed imbibition caused a similar or superior effect to thoseapplied directly to plant culture medium on the nodulatingvariables evaluated. Chitosan hydrolyzed for 24 hours showedthe best results when inducing nodulation (without statisticaldifferences with polymer chitosan) as well as nodular massincrement, probably because of the appearance of smallerchitosan fragments with biological activity as a result ofhydrolysis. Chitosan hydrolyzed for 48 hours showed apositive effect only for the dry biomass of nodules. Thisbehavior was probably due to the degradation of smallerfragments with biological activity derived from 24 hours ofhydrolysis.
