Abstract

Year-round pineapple production in Taiwan by forced flowering is facing adverse environmental challenges in winter such as exposure to low temperatures, drought, and short days.
These conditions stimulated pineapples to flower earlier naturally in the spring (harvest in June to July) and make the production schedule disrupted in fall (August to October) which results in a production gap in Taiwan’s pineapple industry.
To efficiently regulate autumn fruit production, natural flowering was suppressed by application of aminoethoxyvinylglycine (AVG), an ethylene biosynthesis inhibitor.
AVG was applied at different schedules to evaluate its inhibitory effects, and the economic benefits were evaluated.
The pineapple plants of ‘Tainong No. 17’ were planted in April, 2021. An electric quantitative sprayer, developed for precise dose control and application efficiency, was used to apply AVG (10 mL of 100 mg L^‑1 AVG plant^‑1) to 3 replicates (n=50) at two-week intervals.
Seven different treatment schedules (different initial date and number of uses) were starting on 11/17 (7×), 12/1 (6×), 12/15 (5×), 12/29 (4×), 12/1 (5×), 12/15 (4×), 12/29 (3×) and with no treatment as control in 2021. The rates of natural flowering in April 2022 were 0% (11/14, 7×), 0% (12/1, 6×), 38% (12/15, 5×), 87.3% (12/29, 4×), 0% (12/1, 5×), 38.7% (12/15, 4×), and 85.3% (12/29, 3×), respectively.
The natural flowering rates of the control were 99.3%. Moreover, the schedule with 5 times of application from December 15, 2021 to January 26, 2022 had the highest economic benefits, and other schedules starting later than December 15, 2021 did not result in flowering inhibition.
However, the optimal schedule can be adjusted based on climate conditions each year.
