Measuring transpiration of small plants

Posted · Add Comment

Continuous measurements of the water use, or transpiration, of small or herbaceous plants can be difficult. A small weighing lysimeter, also known as a balance or scale, can be used however these often require a researcher to manually read the LCD screen or to have the instrument connected to a PC or laptop. Data collection […]

Flowers and transpiration

Posted · Add Comment

Surprisingly little research has been dedicated to flower water relations. This is despite the vast amount of research on water relations at the whole-plant level, stomatal conductance at the leaf level, and even the water relations of fruits. Flowers have been largely neglected probably due to the difficulty of accurately measuring transpiration rates with a […]

Trees and Water Cycle

What’s going on with trees and water?

Over the last few decades, scientists have turned Earth’s water cycle on its head. We now know that the flow of water between soils, plants and the atmosphere is far more complex than traditionally thought. How scientists discovered multidirectional water flow, also known as hydraulic redistribution, was a work of patience, tenacity and ingenuity. Hydraulic […]
