The author has examined the production of charged hadrons in e/sup +/e/sup -/ annihilation in the upsilon energy region and has attempted to use this information to study the similarities and differences in the fragementation of quark and gluon jets. Major differences in charged hadron production for continuum (q anti-q) and upsilon(1S) (ggg) events include charged particle multiplicities (higher for upsilon data) and greatly enhanced production of baryons on the resonance. Global event characteristics (e.g., event shape) have been studied in hopes of providing some insight as to the basis for these differences. Comparisons have been made between the data and Monte Carlo simulations of q anti-q and ggg events using the LUND model and the Field phase space parton model. Agreements and disagreements between the data and the model are discussed.
