One of the mysteries of the English language finally explained.
Damage to plant tissue, especially bark or fruit, caused by exposure to excessive sunlight.
- ‘The cause of white drupes in blackberries is unknown; some think it may be due to stink bug damage during bloom, sun scald around harvest or another unknown physiological disorder.’
- ‘Maple and poplar, for example, are susceptible to sun scald and desiccation by wind; oaks usually aren't.’
- ‘In the hot southwest, the extra leaves are needed to shade the tomatoes from sun scald and to provide added nourishment to the roots.’
- ‘Older trees are less subject to sun scald because the thicker bark can insulate dormant tissue from the sun's heat ensuring the tissue will remain dormant and cold hardy.’
- ‘Placing some form of protection around the trunk, such as burlap, can help in the prevention of sun scald.’
- ‘Tree wrap has been recommended in the past for use on young trees to protect them from sun scald.’
- ‘Cracks from sun scald can allow insects, fungus, virus, or other damage to gain an entry and begin the process of weakening the tree.’
- ‘To minimize yield losses to sun scald, maintain adequate fertility, practice timely irrigation, stake or trellis to prevent lodging, and maintain proper foliage by controlling defoliating insects.’
- ‘Similar to sun scald on bark, warm days can stimulate cells to be active in leaves, only to be killed by sudden temperature drops when the sun disappears.’
- ‘On young trees ‘temporary ‘branches may be retained along the stem to encourage taper and protect trees from vandalism and sun scald.’’
- ‘When large populations are present they can lower yields by reducing plant vigor and increasing sun scald of fruit through foliage loss.’
- ‘Ripening apples are vulnerable to sun scald, which causes bronzed or bleached spots on the fruit's skin.’
- ‘Silver maple and English walnut are examples of trees that can be damaged by sun scald in summer, but not during winter, when they are completely defoliated anyway.’
