Abstract
A 2-year trial was conducted to investigate the influence of prohexadione-calcium (ProCa) on the fruit quality of summer ‘Jen-Ju Bar’ guava (Psidium guajava L.). ‘Jen-Ju Bar’ trees were treated with various concentrations of ProCa: 0 (as control), 125, 250, and 500 mg L−1, which significantly inhibited spring shoot growth. Summer guava fruits of the trees subjected to ProCa exhibited higher levels of total soluble solids and higher values of total soluble solids to titratable acidity ratio compared with control fruits. Summer guava fruits from trees treated with ProCa were firmer than those from untreated trees. ProCa sprays significantly affected pulp weight, core weight, pulp thickness, and pulp-to-core ratio. No other fruit quality characteristics were significantly affected by ProCa treatment.
