Anadenanthera peregrina var. falcata (angico-do-cerrado), uma leguminosa arbórea, forma associações simbióticas com bactérias fixadoras de nitrogênio (rizóbios) e com fungos micorrízicos arbusculares. Com o objetivo de avaliar a eficiência da inoculação de fungos micorrízicos e rizóbios no crescimento inicial de plantas de angico-do-cerrado, crescidas em solo autoclavado e em solo não autoclavado com e sem inoculação, foi desenvolvido um experimento em casa de vegetação, utilizando raízes micorrizadas de milho e uma mistura de isolados de rizóbios como inoculantes. O crescimento das plantas foi influenciado positivamente pela concomitante inoculação do fungo micorrízico e do rizóbio, tendo as plantas desse tratamento apresentado biomassa cerca de 60 % maior do que o controle no décimo mês. A inoculação de apenas um dos microssimbiontes, entretanto, não provocou diferença na produção de biomassa das plantas. A percentagem de colonização micorrízica foi significativamente mais alta e o número de nódulos maior nas raízes das plantas crescidas no solo não autoclavado, ocasionados pela população de fungos e rizóbios nativos. Nesse tratamento, houve pequeno acúmulo de matéria no xilopódio, provavelmente em virtude do dreno fotossintético por parte dos microssimbiontes, e a concentração de P na parte aérea e xilopódio dessas plantas foi cerca de 1,2 e 8 vezes maior, respectivamente, por causa da colonização micorrízica. The leguminous tree Anadenanthera peregrina var. falcata (angico-do-cerrado) forms symbiotic associations with nitrogen fixing bacteria (rhizobia) and arbuscular mycorrhizal fungi. The aim of this study was the evaluation of the influence of rhizobial and arbuscular mycorrhizal inoculation on the initial growth of angico-do-cerrado plants, in autoclaved and non-autoclaved soil with and without inoculations. The experiment was carried out in a greenhouse using mycorrhized roots of maize and a mixture of rhizobial isolates as inocula. Plant growth was positively affected by dual inoculation of mycorrhizal fungus and rhizobia: plants of this treatment produced 60 % more biomass than in the control in the 10th month. Inoculation of only one microsymbiont, however, did not promote difference in plant growth. Mycorrhizal formation was significantly more extensive and the number of nodules higher in plants of non-autoclaved soil, caused by native soil borne fungi and rhizobia. In this treatment mass accumulation was lowest in the xylopodium, probably because of the photosynthetic drain caused by microsymbionts, and P concentrations in shoot and xylopodium were about 1.2 and 8 times higher in these plants, respectively, due to the mycorrhizal colonization.

Second Law in Classical Non-Extensive Systems ∗

Description:

Equilibrium statistics of Hamiltonian systems is correctly described by the microcanonical ensemble, whereas canonical ones fail in the most interesting, mostly inhomogeneous, situations like phase separations or away from the “thermodynamic limit ” (e.g. self-gravitating systems and small quantum systems) [1, 2, 3].

Equilibrium statistics of Hamiltonian systems is correctly described by the microcanonical ensemble, whereas canonical ones fail in the most interesting, mostly inhomogeneous, situations like phase separations or away from the “thermodynamic limit ” (e.g. self-gravitating systems and small quantum systems) [1, 2, 3]. A new derivation of the Second Law is presented that respects these fundamental complications. Our “geometric foundation of Thermo-Statistics ” [3] opens the fundamental (axiomatic) application of Thermo-Statistics to non-diluted systems or to “non-simple ” systems which are not similar to (homogeneous) fluids. Supprisingly, but also understandably, a so far open problem c.f. ref. [4] page 50 and page 72. 1 Minimize

Equilibrium statistics of Hamiltonian systems is correctly described by the microcanonical ensemble. Classically this is the manifold of all points in the N−body phase space with the given total energy. Due to Boltzmann-Planck’s principle, e S = tr(δ(E − H)), its geometrical size is related to the entropy S(E,N,V, · · ·). This definition does not invoke any information theory, no thermodynamic limit, no extensivity, and no homogeneity assumption. Therefore, it describes the equilibrium statistics of extensive as well of non-extensive systems. Due to this fact it is the fundamental definition of any classical equilibrium statistics. It addresses nuclei and astrophysical objects as well. S(E,N,V, · · ·) is multiply differentiable everywhere, even at phase-transitions. All kind of phase transitions can be distinguished sharply and uniquely for even small systems. What is even more important, in contrast to the canonical theory, also the region of phase-space which corresponds to phase-separation is accessible, where the most interesting phenomena occur. No deformed q-entropy is needed for equilibrium. Boltzmann-Planck is the only appropriate statistics independent of whether the system is small or large, whether the system is ruled by short or long range forces.

Classically this is the manifold of all points in the N−body phase space with the given total energy. Due to Boltzmann’s principle, eS = tr(δ(E − H)), its geometrical size is related to the entropy S(E, N, · · ·). This definition does not invoke any information theory, no thermodynamic limit, no extensivity, and no homogeneity assumption, as are needed in conventional (canonical) thermo-statistics. Therefore, it describes the equilibrium statistics of extensive as well of non-extensive systems. Due to this fact it is the fundamental definition of any classical equilibrium statistics. It can address nuclei and astrophysical objects as well. All kind of phase transitions can be distinguished sharply and uniquely for even small systems. It is further shown that the second law is a natural consequence of the statistical nature of thermodynamics which describes all systems with the same – redundant – set of few control parameters simultaneously. It has nothing to do with the thermodynamic limit. It even works in systems which are by far larger than any thermodynamic ”limit”. Keywords: Classical Thermo-statistics, Non-extensive systems.

Equilibrium statistics of Hamiltonian systems is correctly described by the microcanonical ensemble. Classically this is the manifold of all points in the N−body phase space with the given total energy. Due to Boltzmann’s principle, e S = tr(δ(E −H)), its geometrical size is related to the entropy S(E, N, · · ·). This definition does not invoke any information theory, no thermodynamic limit, no extensivity, and no homogeneity assumption, as are needed in conventional (canonical) thermo-statistics. Therefore, it describes the equilibrium statistics of extensive as well of non-extensive systems. Due to this fact it is the general and fundamental definition of any classical equilibrium statistics. It can address nuclei and astrophysical objects as well. As these are not described by the conventional extensive Boltzmann-Gibbs thermodynamics, this is a mayor achievement of statistical mechanics. Moreover, all kind of phase transitions can be distinguished sharply and uniquely for even small systems. In contrast to the Yang-Lee singularities in Boltzmann-Gibbs canonical thermodynamics phase-separations are well treated. 1 Minimize
