盆栽的首红苹果树在果实生长期间置于日温26℃、夜温22℃或11℃条件下,试验结果表明,果实乙烯大约在同一时间产生。果实成熟时不同温度下果实的氨基环丙烷羧酸含量无差异。果实硬度与可溶性固形物含量无差异。虽然成熟度不受夜温影响,但冷凉气温果实脱落较早,暖夜温下果实着色较少。果个大小不受夜温影响。 The first red apple tree in pot was placed at 26 ℃, 22 ℃ or 11 ℃ during fruit growth. The results showed that the ethylene content in fruit was about the same time. There was no difference in the content of aminocyclopropanecarboxylic acid in fruit at different temperatures when the fruit matured. Fruit firmness and soluble solids content no difference. Although the maturity is not affected by the night temperature, but the cold temperature fruit shed earlier, less fruit coloration at warm night temperatures. Fruit size is not affected by the night temperature.
