Abstract
Enzyme immunoassay was used to study the dynamics of abscisic acid (AA) and wheat embryo agglutinin concentration in Triticum aestivum callus culture at 24 degree C (control) and 40 degree C (experiment). Hyperthermia induced a multiple increase in AA and lectin levels. AA accumulation in cells was a temporary processes which preceded lectin accumulation. Apparently, an increase in AA concentration caused by exposure to heat induced lectin synthesis that could participate in the development of cell defense responses.
