Abstract

Trials were conducted to assess the effectiveness of benzyladenine (BA) as a post-bloom thinning agent for the pear cultivar Packhams Triumph.
Replicated small plot field trials were established in two growing regions in Australia: the Goulburn Valley, Victoria and the cooler maritime climate of southern Tasmania.
Results from the Goulburn Valley showed similar trends to trial work undertaken in Tasmania.
Trial work in both areas examined a factorial combination of concentration of BA (50, 75, 100, 125, 150, 175 or 200 mg/L) and application timings (8, 11, 14, 17, 20, 23 or 26 days after full bloom (DAFB)). BA treated trees were also treated with ethephon at full bloom (FB). Concentrations of 100 to 150 mg/L BA were the most effective at application timings from 11 to 26 DAFB.
