Hello
For the biomass measurements (which are the best measurements to
make in my opinion) you could take a subset of the samples to measure
fresh weight and dry weight. You would probably have to measure fresh
to dry weight ratio of each treatment after the experiment.

Hello,
I've posted before with questions about other methods and got a lot of
responses. Thank you to all who responded before.
I'm going to be starting an experiment in which I plan to measure growth
rates of two different haplotypes of Phragmites australis under varying
water depths and salinities. I plan to use change in height and number of
shoots over time as a measure of growth. I'm planting rhizome fragments.
I'll measure length, diameter, number of nodes, and number of buds before
planting. I'll try to make the fragments as similar in size as possible.
I would like to measure biomass before and after as well (or maybe
instead). But I don't know if measuring fresh biomass before planting and
after harvest is a legitimate method.
Would there be a chance that there would be a difference in moisture
content between each rhizome fragment that could mess up my data?
Is height change a good way of measuring growth in grasses?
Is fresh biomass a good thing to measure before and after a growth
experiment?
Thanks for any advice.
