Although PMS is not routinely used for seedling quality testing per se, it is nevertheless the most common physiological measurement made on reforestation stock. This is because the measurement itself is simple and robust, and the equipment needed-to perform it is reasonably priced and readily available. However, while measurements of PMS are easily made; their interpretation is not always straightforward. In this article we will discuss the meaning and definition of PMS, how it is measured, how the measurements are interpreted and what, if any, value they have as indicators of "seedling quality
