The dynamics of ABA content and activity in the leaves and shoot apical meristems (SAM) of isogenic by E genes soybean lines in the conditions of different photoperiod have been studied in field experiments. ABA content and activity in the leaves and SAM of all soybean isolines increased irrespective of photoperiod duration. However, the magnitude of this process depended on E gene alleles of isoline genotype as well as on photoperiod duration. The PIS (photoperiodic insensitive) lines e1E2e3 and e1e2e3 showed the higher ABA accumulation in SAM both under long and short day. The SD (short-day) lines E1E2E3, E1e2e3 and PIS line e1e2E3 showed the higher content and activity of ABA in the leaves under long day. On the contrary, in short day ABA level was higher in the SAM of these isolines. It is supposed that E genes probably affect the transition to flowering of soybean under different photoperiod through their participation in the regulation of activity, accumulation and balance of ABA in the leaves and shoot apical meristems.
