ABSTRACT: The Amazonia Forest is an important biome that possesses great diversity of fauna and flora, which can play a significant role in several science areas, specially, the gene reserve for the future of humankind. Nevertheless, it is a very poorly understood environment, particularly the basis of this ecosystem, its soils. This study was conducted to gain insight in the mineralogy of important soils classes of the Amazonia sedimentary basin. The soils in the upland position in the landscape are developed from tertiary sediments belonging to the Alter do Chão series and those in the floodplain position are derived from quaternary, more specifically, Holocene´s sediments. Sand, silt and clay fractions were separated and X-ray diffraction analysis was conducted. Very simple mineralogy composed basically of quartz in the coarser fractions and kaolinite, goethite and anatase for the finer fraction was found for the Oxisol, the Ultisol and the Entisol from an upland toposequence but differences in kaolinite crystallography could be noticed among them. Gibbsite was virtually absent, in spite of the advanced degree of development of most of these soils. More distinctive mineralogy was revealed for the soils developed in the more recent sediments with quartz and feldspars in the sand and silt fractions and a suite of 2:1 minerals also appearing in their clay fraction, besides kaolinite and goethite. In one upland soil petroplinthite is the main feature and its mineralogy reflected its environment of formation which is usually associated with level to gently sloping areas with fluctuating water table.

Peach [Prunus persica (L.) Batsch, cv. Chiripá] fruit harvested from plants sprayed with gibberellic acid (GA3), at the beginning (T1) and end of pit hardening (T2), kept under cold storage (CS) and controlled atmosphere (CA/CS), and from plants not sprayed with GA3 (Control) and kept under CS, were evaluated in terms of fruit size and mass, ripening, occurrence of woolliness and expression of supposedly related genes and proteins. Peaches not sprayed with GA3 and submitted to CS had a high incidence of woolliness, high mRNA abundance of vesicle transport genes and low mRNA abundance of genes associated with cell wall loosening, ethylene biosynthesis and heat shock proteins (HSPs). Early GA3 spraying did not delay ripening but induced an increase in fruit size. In addition, it also induced a climacteric rise and prevented the occurrence of woolliness after CS. Woolliness prevention as a result of either GA3 or CA/CS treatments resulted in higher abundance of mRNAs associated with cell wall metabolism, mitochondrial HSPs and 1-aminocyclopropane-1-carboxylic acid oxidase (ACCO). A unique GA3 response consisted of a high mRNA abundance of genes and/or proteins such as HSP40-1er, HSP40-2er, HSPCTR2, Beta-mannosidase (Beta-Man) and Alfa-l-arabinofuranosidase (Alfa-Ara). |
