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.
