ABSTRACT The curing before storing the tubers is necessary for the formation of damage periderm, promoting greater post-harvest conservation. In which, the rate curing and the maintenance of the quality of the tubers depends on the temperature. This way, the search aimed to determine the effect of the curing temperature on the regeneration of the damage periderm and on the carbohydrate metabolism of cultivar Markies and Challenger potatoes tubers destined for industry. For this, the curing was carried out for 14 days on tubers with excoriation injury and tubers without excoriation (control) at temperatures of 8, 14 and 20 °C (RH ± 90%). The fresh mass loss rate (FMLR) daily was higher in the excoriation tubers. The excoriation injury and the temperature of 8 °C increased the total soluble sugar (TSS), reducing sugars (RS) and non-reducing sugars (NRS) of the tubers of ‘Markies’ and TSS of ‘Challenger’. The excoriation injury tuber the process of cell division was induced in the periclinal plane, forming phellogen, with few layers of collapsed cortical cells. In both cultivars, at 14 °C the new phellogen became more evident and at 20 °C some layers of a new cork were formed. In ‘Markies’ the development of new periderm was earlier than in ‘Challenger’, even at 8 °C. It is concluded that the temperature of 14 ºC provided better curing and regeneration of the excoriation periderm tubers maintain post-fry quality of potatoes destination by industry processing.

Resumo A ciência da complexidade apresentou uma proposta de ruptura paradigmática no meio científico. Entre outros avanços sua maior contribuição é na compreensão dos sistemas dinâmicos nãolineares, que predominam na natureza, revolucionando assim o conceito e análise dos sistemas físicos. Várias teorias da complexidade podem ser aplicadas à análise do relevo, sob a ótica dos sistemas não-lineares, e este paradigma possui potencial de revolucionar os estudos dos sistemas morfológicos, além de integrar diversos tópicos que antes eram analisados isoladamente. Neste trabalho, apresenta-se os conceitos das Estruturas Dissipativas, Teoria do Caos, Teoria das Catástrofes e Geometria Fractal, buscando correlacionar com análise dos sistemas geomorfológicos dinâmicos não-lineares sustentando-se que essas teorias possuem potencial teórico-metodológico plenamente aplicáveis em estudos de geomorfologia.

Abstract The complexity science presented a proposal for a paradigmatic rupture in the scientific environment. Among other advances, his greatest contribution is in the understanding of nonlinear dynamic systems, which predominate in nature, thus revolutionizing the concept and analysis of physical systems. Several complexity theories can be applied to relief analysis, from the perspective of non-linear systems, and this paradigm has the potential to revolutionize the studies of morphological systems, in addition to integrating several topics that were previously analyzed in isolation. In this work, the concepts of Dissipative Structures, Chaos Theory, Catastrophe Theory and Fractal Geometry are presented, seeking to correlate with the analysis of non-linear dynamic geomorphological systems, sustaining that these theories have theoreticalmethodological potential fully applicable in studies of geomorphology.

ABSTRACT The breakdown of dormancy and early sprouting is one of the main causes of losses of stored potatoes. Sprouting control becomes important especially when tubers are submitted to long-term storage for further processing by the potato industry. The objective of this work is to evaluate the effect of organic sprout inhibitors, eugenol and menthol essential oils, on the suppression of growth on non-dormant ‘Asterix’ tubers stored at 8 °C. Administration of eugenol and menthol essential oils reduced the number and the length of sprouts during cold storage up to fifty days. Nevertheless, the essential oils stimulated the break of bud apical dominance, stimulating auxiliary buds growth. The effect of the oils was restricted to inducing necrosis of superficial sprout cells without any apparent effect on the skin periderm structure. Repeated applications of oils are necessary to prolong the inhibitory effects of the essential oils on sprouts growth.
