The insecticide tiamethoxam, the best resistance inducer for cold storage of tangor Ortanique

This study aimed to evaluate changes in the fruit composition?quality of Tangor Ortanique (Citrus sinensis x C. reticulata) after treatment with inducers of resistance in pre-harvest and cold storage. The pre-harvest treatments were: control (T1), selenium (T2), silica (T3), Acibenzolar-Smethyl (T4), methyl jasmonate (T5), tiamethoxam (T6)(*) andimidachoprid (T7). The storage temperature was at 5?1 ?C with a relative humidity of 90?5%, with subsequent shelf life simulation of 7 days at 22?2 ?C, in the following periods, in days, of 0 (P1), 15 (P2), 30 (P3), 45 (P4) and 60 (P5). The evaluations were: color (L * and Hue angle); pH; titratable acidity (TA); soluble solids (SS); ratio; and ascorbic acid (AA). By observing the L* data, all treatments were superior than?control. In the Hue angle, the fruits of T5 and T6 kept better?characteristics. For pH and ratio variables there was no?significantly difference between treatments; while for AT?and SS, T3, T4 and T5 showed lower levels. As for AA, T3?and T4 fruits showed lower levels. Regarding to the storage?time, all the evaluated values d ecreased over time, but the?treated fruits maintained overall characteristics. Among the?analyzed treatments, T5 achieved higher fruit qualities. Financial support: CNPq, CAPES and Embrapa.
