abstract = "Brassinosteroids are known to affect sourcesink
relationships in plants, possibly by
affecting auxin redistribution in plants, which
has an indirect effect on the metabolism
of carbohydrates, and thus on growth and
development of plants. Since source-sink
relationship are main determinante of crop yield,
the need for a more precise characterization
of the effect of brassinosteroids is very
important. One of the methods of the studyng
the issue is thermodinamic, i.e. expression
of plant growth and development through
quantitatively verifiable energetic parameters
(enthalpy, entropy, Gibbs free energy), i.e.
mostly qualitative growth parameters. We
tested this approach at three levels of maize
development: a) seedlings; b) adult individual
plants; c) adult plants in the field. Since the
methods for determining thermodynamic
parameters are destructive, the proposed
approach was whole implemented only at
the level of seedlings, partly at the level of
individual adult plants, while the determination
of thermodynamic parameters at the field level
was not implemented. In addition to other
measurements, a regression comparison of
the mentioned thermodynamic parameters
and the concentration of important sugars
was performed in different corn seedling parts.
The results indicate that the germination and
initial seedling growth influenced by the flow of
sugars from remaining seed (as source organ)
towards plumule and radicle (as sink organs).
Also, alterations in Gibbs free energy play a
significant role in these sugar transfer within
maize seedlings. In the context of the obtained
findings in corn seedlings, the result of the
experiments conducted at individual adult
maize plants and corn plants in the field are
disscused.",
