Abstract:Using hybrid offspring of P. ussuriensis Max. and P. bretschneideri Rehd as materials, effects of differ-ent ways of planting and cultivation of hybrid seedlings in other place on earlier fruit setting were studied. The re-sults showed that there were significant difference in growth and development with different sowing method, i.e., out-door plus small tunnel, sunlight greenhouse and directly outdoor sowing. After seedling transplantation, with the in-crease of tree age, the difference of hybrid seedlings growth among different sowing treatments became less. Hybridseedlings which were cultivated in other place grew strongly compared with that cultivated in original place, so itcould be an effective method to shorten the juvenile period of pear hybrid seedlings in northern China.
