Abstract: In order to learn application effect of plant growth regulators in production of Korla fragrant pear, taking 20-year Korla fragrant pear as test materials, influences of spraying different plant growth regulators at different concentrations on fruit characteristics and yield of Korla fragrant pear were researched through ifeld experiments. The results showed that compared with the control treatment without spraying any reagent and clean water, it could increase the fruit setting rate, single fruit mass and yield of Korla fragrant pear, and decrease fruit stalk length and fruit shape index, to spray PBO, PP333 and sodium nitrophenolate. In terms of improving fruit setting rate and yield of Korla fragrant pear, PBO reagents had better spraying effects than PP333 and sodium nitrophenolate. And 300 times PBO reagent had best effect, and improve fruit setting rate by 8.84%and improve yield by 63.41%compared with the control treatment.
