FERREIRA, Ladislau Soares et al. Acid soluble invertase and insoluble activity in potato tuber subsequent reconditioning after storage in different temperatures. Ciênc. agrotec. [online]. 2007, vol.31, n.6, pp. 1610-1615. ISSN 1413-7054. http://dx.doi.org/10.1590/S1413-70542007000600002.
The aim of this work was to quantify the activity of the acid soluble invertase enzymes and insoluble invertase in tubers of potato genotypes: Atlantic, Pérola, Asterix and C-1786-6-94 stored in different temperatures with recondition. One determined the activity of the acid soluble enzymes and insoluble invertase at 0 30 and 60 days of storage. In 30 days of storage the activity of the two enzymes was stimulated by the temperature at 4ºC. The recondition from 4º C to 20º C reduced the activity of the insoluble and acid soluble invertase in all cultivars, however in different way among them. The storage at 12ºC and the reconditioned from 12º C to 20º C had little influence on the activity of the acid soluble invertase. The activity of the insoluble invertase under 12º C was increased at 30 and 60 days of recondition in C-1786-6-94 clone and Atlantic cultivar. The storage at 20ºC did not alter the activity of the acid soluble invertase enzyme and insoluble invertase for the cultivars studied.
