Transplant Stress Index: A proposed method of quantifying planting check

  • David B. South
  • Janusz B. Zwolinski


This paper demonstrates a simple way of estimating the intensity and duration of planting check by examining height growth patterns. A “transplant stress index” is determined by the relationship between initial seedling height and subsequent height growth. This index is defined as the slope of a linear relationship between initial height and height increment. If the slope is negative, the plants (as a population) are said to be experiencing planting check. When the slope is approximately zero, the stock is said to be recovering from planting check. A steep positive slope suggests the stock has recovered from planting check. TSI values were determined for several conifers including Pinus elliottii Engelm. var. elliottii, Pinus taeda L., Pinus radiata D. Don, Picea sitchensis (Bongard) Carrière, and Larix× eurolepis Henry.
