Abstract

Abstract: Katy apricot variety was used as materials to research effects of plant growth regulators on fruit growth andd evelopment in greenhouse. Results showed that fruit growth was promoted after applied with 50 mg/ L GA3 and 50mg/ L6??BA: fruit length, diameter, fresh weight and fruit volumewere all higher than control??s, especially with GA3??The cytolog??ical research indicated the reason promoting fruit size was an increase of the number of fruit cells.While the effect of 40mg/ L NAA was no significant difference with control.All the three treatments advanced the sugar content, the effect of 6??BA sprayed was the best, but the effect on acid content of fruit was no significant difference among treatment.

Key words: Plant growth regulator, Katy apricot, Growth, Development
