A. Royo-Esnal and M.L. López. 2012. Fresh matter production by two forms of Oxalis latifolia as influenced by soil and climate. Cien. Inv. Agr. 39(2): 309-320. Oxalis latifolia is a widely distributed weed that mainly affects corn fields, orchards, plant nurseries and gardens. Two forms of the weed have been identified: the common form, with fish-tailed leaflets, bulbils growing on stolons and dark pink flowers, and the Cornwall form, with rounder leaflets, sessile bulbils and whitish-pale pink flowers. In this study, the fresh matter production, expressed as the increase of the bulbs' fresh weight, of both forms was compared during two growing seasons in two locations. The bulbs were grown in pots from spring to autumn, and different aspects of growth were measured at the end of each season. The total fresh matter production,
