Changes in endogenous phytohormone level were determined with two different fluences of ⁷Li equivalent to radiation doses of 1 Gy and 4 Gy. To estimate the endogenous indole-3-acetic acid (IAA), phenoxy acetic acid (PAA), and abscisic acid (ABA) levels, indirect ELISA was performed with the help of antibodies raised against each hormone. In samples at later stage, dose dependent response was apparent in PAA. Results showed that <i>in vivo</i> content of each hormone increased with radiation treatment except ABA. </smarttagtype></smarttagtype>
