Brassinosteroids (BRs) are a class of plant hormones that play important roles in regulating
various physiological and developmental processes in plants. One of the most effective BRs involved
in modulating crop growth is 24-epibrassinolide (24-EBL). The effects of different concentrations
of 24-EBL on various biochemical and biophysical parameters critical to early growth stages and
seedling development were investigated using two maize hybrids, ‘ZP 434’ (a new-generation hybrid)
and ‘ZP 704’ (an older-generation hybrid). The evaluation of results is based on measurements of
germination percentage, morphometric parameters, redox status, comparative analysis of thermodynamic
parameters (such as Gibbs free energy, enthalpy, entropy), and the concentration of specific
sugars in different parts of maize seedlings. The results indicate that the germination and initial
growth of maize seedlings are influenced by the flow of crucial sugars from the remaining seed (as a
source of nu...trients) towards the plumule and radicle (as sink organs). Furthermore, alterations in
Gibbs free energy play a significant role in these sugar transfers within the maize seedlings. The seed
germination was most affected by the highest concentrations of 24-EBL, showing inhibitory effects,
whereas lower and moderate concentrations of exogenously added 24-EBL exhibited a beneficial
influence on the initial phases of seedling growth. The mentioned approach gives new insights into
source–sink relationships and can be used as a quantitative measure of the germination energy, which
until now has been a qualitative criterion in seed science.
