Abstract:Intense solar radiation is one of the factors contributing to fruit sunburn. Therefore, a study of the effect of light intensity on changes of fruit surface temperature helps gain a better understanding of the actual role of sunlight in inducing fruit sunburn. The present study was conducted with apples (Malus domestica Borkh., cv: Fuji) to document the relationship between light intensity and fruit surface temperature. Copper-constantan thermocouples were attached to the sun-exposed side of fruit on the s...
