| 摘 要： | 使用自制的日灼诱导设备，在无风或微风的晴天对活体果实进行田间日灼诱导，通过改变诱导室内的气温来控制和调节果面温度，从而确定了不同苹果品种果实发生日灼的阈值温度。试验证明： 自制的诱导设备运行平稳，诱导期间可保持果温基本稳定，大多数情况下，处理期间果面平均温度与实际设定温度的差异小于0．12℃ ，温度变化幅度一般小于±0．5℃ 。本试验所测定的9个苹果品种日灼阈值温度为(45．9±0．5)℃ (48．5±0．5)℃。光照对日灼发生有重要影响，即使在同样的阈值温度下，有光的处理果实发生日灼，而无光的处理则不发生日灼。

| Abstract: | A special inducing device for fruit sunburn was made to study the“threshold temperatures’’withattached fruit．The results showed that，the device worked perfectly in calm ，clear and sunny days．Th e diference between~tual average fruit temperatures during induction and designed temperature Was less than 0．12~C in most cases and the fluctuation of temperatures during treatment Was less than ±0．5℃ ．]'his technique could meet therequirement for field induction of fruit sunbum．Th ere ested some differences among 9 cultivars examined in resistance to thermal injury，ranging from (45．9±0．5)oC to(48．5±0．5)oC．Light Was important in inducing fruitsunburn because at the sane“threshold temperature”， fruit got sunburned under natural light but didn’t necessarily without sunlight． |
