Thermodynamics of Seed and Plant Growth

Effects of different cropping systems and weed management methods on free energy and content of pigments in maize

“…It means that these two genotypes reacted differently to the cropping systems, with a domination of exergonic processes and energy releasing. Such energy can be released into the external environment or spent on some other processes, such as biosynthesis in coupled reactions (Kadem and Caplan, 1965;Dragičević and Sredojević, 2011). From that aspect, Table 2), which, coupled with the lower average ∆G obtained in MSW rotation, is an indication of system efficiency provided by treatments.…”

“…From that aspect, Table 2), which, coupled with the lower average ∆G obtained in MSW rotation, is an indication of system efficiency provided by treatments. This could also signify a domination of exergonic reactions (Sun, 2002;Dragičević and Sredojević, 2011), which are spontaneous. This energy release could contribute to an increase in growth/yielding potential of the system and is reflected in the negative interdependence between ∆G and grain yield in MSW and MWS rotations (R 2 =0.860 and R 2 =0.467, respectively, Figure 4).…”

“…Sun (2002) recognized free energy input by water as a presumable plant growth factor. According to the Hess Law, free energy is cumulative, irrespective of its origin; hence, all the potential energy present in a plant system is given by the sum of individual energy states, which could be successfully used by the system in coupled reactions (Kadem and Caplan, 1965;Dragičević and Sredojević, 2011). It is also well-known that plants react to stress by alterating their chlorophyll and carotenoid contents.…”

Clues on an intraspecific communication system in early plant establishment: The seed-seedling transition from the point of view of a crosstalk between information theory and gene expression

“…There is a tendency of nature to equalize processes as order passes into disorder, that is, when molecular disorder increases. Thus, Ludwig Boltzmannn, applying the concept to physics, in 1896, stated that entropy can be defined as a measure of the degree of system disorder (Leff, 2007; Haynie, 2008; Dragicevic and Sredojevic, 2011). This explains the close relationship between entropy and embryo development under a standard temperature, as was the case with the experimental environment.…”

“…In thermobiology science, there are scientists that consider thermodynamic entropy and information entropy as synonyms, which is called the statistical entropy of the thermodynamics of the Boltzmannn theory (Wehrl, 1991). By the way, the little that is currently present in the entropy of germination sensu stricto is based on Boltzmann theory (see Dragicevic and Sredojevic, 2011), probably due to the difficulty of determining the information entropy during germination per se . However, it has recently been demonstrated that when using water dynamics in germinating seeds at a standard temperature (a highly related character to the germinative metabolic processes), it is possible to calculate the information entropy in a much easier, robust and practical way (Ribeiro-Oliveira, 2015).…”
