Hi there,
I have a question regarding different units being used in plant physiology for measurement of different stresses
e.g 10 % of MPa PEG
-0.3 MPa of PEG
0.5 mM Salt.
why some people measure water stress in percentage other in MPa or mM. Are they interconvertible ?. if yes what does a 10 % of MPa PEG means ? what its equivalent in MPa ?
could some can elaborate the whole concept please and how to convert one unit to another ?
Thanks in advance.
