P. Martonfi et al., CHEMOTYPE PATTERN DIFFERENTIATION OF THYMUS PULEGIOIDES ON DIFFERENT SUBSTRATES, Biochemical systematics and ecology, 22(8), 1994, pp. 819-825
Relationships between soil chemistry and population chemotype structur
e of Thymus pulegioides have been studied. The analysis of correlation
s suggest that an increased carbonate content in soil decreases the ch
emotype diversity of a population (as calculated by use of the Shannon
index): the propertion of linalool chemotype plants rises and that of
phenol chemotype plants declines. In addition, the chemotype diversit
y decreases with increasing frequency of linalool chemotype, and incre
ases with increase of carvacrol chemotype.
