Anatomical and morphological spine variation in Gymnocalycium kieslingii subsp. Castaneum (Cactaceae)

Original language description

Although spine variation within cacti species or populations is assumed to be large, the minimum samplesize of different spine anatomical and morphological traits required for species description is less studied. There are studies where only 2 spines were used for taxonomical comparison amnog species. Therefore, the spine structure variation within areoles and individuals of one population of Gymnocalycium kieslingiisubsp. castaneum (Ferrari) Slaba was analyzed. Fifteen plants were selected and from each plant one areolefrom the basal, middle and upper part of the plant body was sampled. A scanning electron microscopywas used for spine surface description and a light microscopy for measurements of spine width, thickness, cross-section area, fiber diameter and fiber cell wall thickness. The spine surface was more visible anddamaged less in the upper part of the plant body than in the basal part. Large spine and fiber differenceswere found between upper and lower parts of the plant body, but also within single areoles. In general, the examined traits in the upper part had by 8-17% higher values than in the lower parts. The variationof spine and fiber traits within areoles was lower than the differences between individuals. The minimumsample size was largely influenced by the studied spine and fiber traits, ranging from 1 to 70 spines. Theresults provide pioneer information useful in spine sample collection in the field for taxonomical, biomechanicaland structural studies. Nevertheless, similar studies should be carried out for other cacti speciesto make generalizations. The large spine and fiber variation within areoles observed in our study indicatesa very complex spine morphogenesis. (C) Roman Gebauer et al.
