Comparison of two plant water extraction methods for ...

Here we compare two water extraction methods: cryogenic distillation, which extracts all water from plant tissues, and a Scholandertype pressure chamber, which extracts water from xylem tissue. Scholandertype pressure chambers are typically used to determine leaf and stem pressure. Here, we used the pressure chamber to force water out of xylem tissue for collection and subsequent isotopic ...

When plants absorb water from the ground they filter out many impurities, and you can extract this clean water from them. Plants transpire water, meaning that water vapor evaporates from the leaves, and this water can be collected. The great thing is, this process doesn't harm the plant and can be repeated over and over again on different branches, and works relatively quickly. Thanks to ...
