How do you measure the biomass?

The basic technique for measuring biomass is the harvest method: Simply remove biomass, dry it in an oven to remove water, and weigh it. (Because the water content of plants can vary dramatically day to day, even hour to hour, drying to get "dry weight" is a more stable measure of biomass than is fresh weight.)

Considering this, what is used to measure the growth of plants?

An auxanometer (Gr. auxain= "to grow" + metron= "measure") is an apparatus for measuring increase or rate of growth in plants. In case of an arc-auxanometer (see picture), there is a wire fixed with the plant apex on one end and a dead-weight on the other. It passes over a pulley which has a pointer attached to it.

What is the growth of plant?

Requirements for Plant Growth. The major difference is the method by which the plants are supported and the inorganic elements necessary for growth and development are supplied. Temperature. Plants grow well only within a limited temperature range.

Why is dry mass used as a measure of growth in plants?

(2) The dry matter of a sample or of an object when completely dried (lacks or excluding water). Dry mass is a more reliable measure of mass than fresh mass because the former excludes the fluctuating water concentrations in the biological material measured which is present in the latter.
