The production of K^0_S mesons and Lambda baryons in quark and gluon jets hasbeen investigated using two complementary techniques. In the first approach,which provides high statistical accuracy, jets were selected using differentjet finding algorithms and ordered according to their energy. Production rateswere determined taking into account the dependences of quark and gluoncompositions as a function of jet energy as predicted by Monte Carlo models.Selecting three-jet events with the k_perp (Durham) jet finder (y_cut = 0.005),the ratios of K^0_S and Lambda production rates in gluon and quark jetsrelative to the mean charged particle multiplicity were found to be 1.10 +/-0.02 +/- 0.02 and 1.41 +/- 0.04 +/- 0.04, respectively, where the firstuncertainty is statistical and the second is systematic. In the secondapproach, a new method of identifying quark jets based on the collimation ofenergy flow around the jet axis is introduced and was used to anti-tag gluonjets in symmetric (Y-shaped) three-jet events. Using the cone jet findingalgorithm with a cone size of 30 degrees, the ratios of relative productionrates in gluon and quark jets were determined to be 0.94 +/- 0.07 +/- 0.07 forK^0_S and 1.18 +/- 0.10 +/- 0.17 for Lambda. The results of both analyses arecompared to the predictions of Monte Carlo models.
