Quick Answer
Types of trees less effective for transpiration bag use include those with thick, waxy leaves or those that have low photosynthetic rates, such as cacti and succulents, as well as trees with dense foliage or broad leaves, like oak and maple. ---
Choosing the Right Tree for Transpiration Bag Use
When selecting a tree for a transpiration bag, it’s essential to choose one with the right characteristics. Trees with thin, broad leaves like willow, cottonwood, or silver maple are ideal for transpiration bag use. These trees have a high rate of transpiration and are more likely to produce a steady flow of water.
Measuring Transpiration Rates
To determine the effectiveness of a tree for transpiration bag use, measure its transpiration rate. This can be done by weighing the tree’s leaves at regular intervals and calculating the difference in weight over time. Aim for trees with a transpiration rate of at least 1-2 grams per hour per square meter of leaf area.
Factors Affecting Transpiration Bag Efficiency
Other factors can affect the efficiency of a transpiration bag, including the tree’s water stress levels, soil moisture, and temperature. Ensure the tree is receiving adequate water and is not under drought stress. A temperature range of 65-85°F (18-30°C) is ideal for optimal transpiration rates.
