Abstract
THE path of the plant physiologist who sets out to make accurate measurements of the effect of light and temperature on the growth and multiplication of the plant is beset with many hindrances. In the first place, the plant, the system which he investigates, is never completely reproducible. No two living things are exactly alike, and the variability of the biologist's material is an ever-present threat to the accuracy of his work. Something can be done to reduce the variability by selecting the progeny of a single individual, using clonal or pure-line plants. After the most careful selection, however, some variability inevitably remains; this must be evaluated by statistical methods.
