Foliar analysis of natural deciduous tree species of basswood (Tilia americana L.) (BA),
American beech (Acer grandifolia Enrh) (BE), and white ash (Fraxinus americana L.)
(WA) was carried out in ۱۹۹۴ in southern Quebec. The Diagnosis and Recommendation
Integrated System (DRIS) was developed from the traditional method to find the preliminary
norm and indices of N, P, K, Ca, and Mg for the above species. The growth decade
۱۹۸۳-۱۹۹۴ in a high yielding sub-population was used to develop DRIS norms for the
identification of DRIS functions and indices in relatively depleted levels of those elements
in the declined growth of three species. Foliar nutrient deficiencies were found with K
(-۳.۷۲) and N (-۲.۹۶) for basswood, Ca (-۱۰.۴۳) and Mg (-۴.۹۳) for beech, and N (-۶.۱۶), Ca
(-۲.۵۶) and K (-۲.۰۵) for white ash. The DRIS analysis indicated that basswood and white
ash were relatively depleted of K and N, while beech had a deficiency of Ca and Mg, and
white ash had a limitation of N. These results suggest the usefulness of DRIS for foliar tissue
analysis as an indicator of nutritional status and elemental stresses in natural forests.
The DRIS indices were also discussed from the traditional approach.
