Is it possible to block the plants transpiration and what phenomenon would be disturbed?
Yes, transpiration can be blocked. This website gives definitions for products that can be used to prevent water loss: http://www.gsihorticultural.com/antidess… One of the four major theories of upward transport in a stem (specifically in the xylem tissue) is “transpiration pull/cohesion tension.” What this means is that water loss from a leaf by transpiration is replaced by water molecules behind it. Because of transpiration, water is “pulled” up the stem of a plant. Therefore, blocking transpiration would disturb the rise of water going up the stem into the leaves. To a lesser degree, here’s another phenomenon that would be disturbed: EVAPORATION of water from transpiration causes COOLING This is significant in forest areas. A large maple tree losses up to 50 gallons of water due to transpiration on a hot day. Besides shade, this is another reason why forest areas are cooler than areas without trees.
