Abstract

The comparison of primary adventitious roots structure was done in a survey study of 17 Solanum tuberosum cultivars differently tolerant to drought by means of microscopic methods. Cell wall autofluorescence combined with aniline blue treatment of handmade sections was shown to be a convenient method for fast examination of large amount of plant material. Secondary structure limited to the formation of vascular cambium and its derivative tissues was found in all the cultivars examined. Anatomical differences were found between cultivars, individual plants and individual roots, and they were most evident in regard to the extent of secondary structure formation and number of primary vascular tissues strands. By means of image-analysis method, cross-section areas of the root and xylem were measured in 16 cultivars, and by means of statistical analysis significant differences were found between cultivars in regard to these traits.
