Another choice for measuring tree photosynthesis in vitro.

ABSTRACT:

Background

In the case of tall trees in the field or in rugged terrain where an instrument cannot be placed operationally, beveling is a popular method used to measure in vitro photosynthesis. However, some studies and our own research have shown that net photosynthesis values measured in vitro are generally significantly lower than values measured in situ.

Methods

To develop a more accurate and applicable method for in vitro determination of photosynthesis, we evaluated five different methods for preparing detached tree branches to measure photosynthesis and gas exchange in vitro (beveling, cracking, splitting, girdling, and immersion in salicylic acid solution). Ten common tree-species were used.

Results

By comparing light response
