Abstract

A controlled temperature room experiment evaluated the effects of four day/night tem-perature treatments on flowering, fruit set and growth of Fuyu, the most important non- astringent persimmon cultivar grown in Australia. Fruit set of hand-pollinated flowers at 17/12C and 22/17C was similar and averaged 53.6 and 54.9%, respectively. In contrast, fruit set of hand-pollinated flowers at 27/22C and 32/27C was significantly reduced by 58 and 77%, respectively. For the three higher temperature treatments, fruit set of non- pollinated flowers was very low (< 4.0%) compared with fruit set at 17/12C, which averaged 50.2%. The greater fruit set of non-pollinated flowers at 17/12C may have been due to a combination of increased flower size and reduced vegatative growth under these conditions. Higher shoot starch concentrations at anthesis were recorded with decreasing temperature, presumably due to reduced growth (17/12C, 3.1%; 22/17C, 1.9%, 27/22C, 0.85%, 32/27C, 0.90).
