During allelopathic investigations of interrelationships among different
plant species in their natural sites, special attention is paid to the presence of
phenolic acids (PAs) in dominant plants, plant litter and in the soil. They are
localized in all plant organs, both as free and in bound forms i.e. associated
with other compounds such as lignin (Kögel and Bochter 1985; Kögel 1986)
and polysaccharides of cell walls (Whitmare 1976). Phenols are transferred
from plants to the litter and soil by foliage and stem leaching, leaf fall, root
exudates, microbial decomposition of plants remains, (mainly the
degradation of lignin). PAs have been identified as the main phytotoxins of
some plant species (Lodhi and Rice 1971; Chou and Muller 1972).
Phytotoxins play a significant role as germination inhibitors that affect
growth of seedlings, soil nitrification and nitrifying bacteria (Lodhi and
Killingbeck 1980, Einhellig et al.,1982, Khan and Ungar, 1986). This chapter
describes the methods for extraction, detection and measurement of total
phenolics and phenolic acids in dry plant material (vegetative plant parts,
mostly leaves), plant litter and soil (organic and mineral); method of induced
chlorophyll fluorescence kinetics of photosystem II for determination of
photosynthetic efficiency; methods for chlorophyll content determination
and methods of biotests.
