Orchids and heat stress - why do leaves burn in the sun?

Many of us have been faced with sun burn on our orchids. These plants are simply not suited for direct hot sun. Let's try to find out what is actually happening. ▼▼▼More info bellow!▼▼▼ I have talked about sunburn in the past in a more simple way, you can view the video here    • What are sunburns on orchid leaves and how...   Actually the process is quite interesting. According to this article http://www.sciencedirect.com/science/... plants and not only are capable of producing heat shock proteins. These structures help cellular strength against stress factors and keep plants intact in severe conditions. Being that orchids are not those types of plants that grow in extreme environments, they were never forced to find ways of adapting to such extremes. While they are tolerant to a degree of stress, there is a limit to which this can be stretched. When it comes to heat and sunburn, orchids are very poorly adapted in comparison to other sun tolerant plants. Thus, if a certain limit is exceeded, an orchid can scorch in a matter of hours. -------------------------------------------------------------------------------------- ✿ Want to send me something?
