Protecting apples in the sun - pass the sun block?


Apples can suffer from excess sunlight and heat. The stress causes sunburn or sunscald.

The effect on the apple is surface discolouration and hence degrading of the fruit. This can be a severe loss to the grower. Hence the experiment here where two factors are being examined. Firstly, the use of nets over the orchard provides shade and should reduce the risk of sun burn. Secondly, different coloured net are being tried. As these let through different wavelengths of light, there maybe different responses from the apples.
