Why sunscald occurs in Kiwi?

Sun scorch or sunscald is a physiological disorder in which fruits are affected due to direct exposure to sunrays and because of that, the fruit becomes insipid, unfit for human consumption and processing. The affected surface of the fruit develops typical brown, leathery and sunken scars.  In summer, high temperature (> 35 °C) accompanied by high insulation and low humidity may cause scorching of leaves.

The damage from sunscald can be minimized by thatching the branches with paddy straw, dry grass or hay as this avoids the direct exposure of fruits to sunlight.
