摘要: Feverfew plants (Tanacetum parthenium L. Schultz-Bip) were cropped in pots containing substratum maintained at 90%, 70% and 50% of field capacity. The evaluated for the height, accumulation fresh mass aerial part, relative chlorophyll proline content. content was estimated using a portable meter (SPAD-502), while by colorimetry. Reductions 16% height 22,5% part grown capacity verified, being compared with average 90% expanded leaves, any water levels, decreased time, indicating tendency to senescence leaves. Plants presented about 30% more chlorophyll, capacity, during whole accompanied time. Also, higher, osmotic adjustment stress due deficiency. largest leaves under deficiency can be used as indicative.
