Estudio sobre la estructura y variabilidad de la oca (Oxalis tuberosa Mol.)
From the study on the morphology, structure and variability of Andean tuber "Oca" (Oxalis tuberosa Mol.), the following conclusions may be drawn: Oxalis tuberosa Mol. is an annual dicotyledonous herbaceous plant, which is usually propagated by tubers. It is a polyploid (68-70 somatic chromosomes) and as such the most promising selection work will be the establishment of clones. Under different environmental conditions outside its own habitat these plants behave in a different manner in regard to their growth habit, flower abundance and color. Stolons are cauline and their structure is similar to shoots. Oca varieties are easily identified by the color and form of their rhizomes. This is the usual way to make the identifications. It was found that the intense coloring of the stem is closely related to the color of the rhizomes. All plants with green stems have white rhizomes. Great quantities of starch are found in the inner layers of the cortex and less in the medullar part. Cárdenas" statement that all cultivated oca flowers are yellow-orange in color is corroborated
