“…the accumulation of TSC may have contributed to the maintenance of the water status of the plant, favoring tissue protection and physiological processes, which is an important mechanism in the tolerance of V. surinamensis to the presence of Cd, at least during the experimental period. The results obtained in present study in relation to total soluble carbohydrates were evidenced by Anand et al [23].…”

Biochemical metabolism of young plants of Ucuúba (Virola surinamensis) in the presence of cadmium

Virola surinamensis is a forest species widely distributed in the estuaries of the Amazon. These ecosystems are susceptible to contamination by Cadmium (Cd), indicating that the plant has strategies for tolerating this metal. The aim of this study was to assess the nitrogen and carbon metabolism of young plants of Ucuúba (Virola surinamensis) in the presence of cadmium with the perspective of the phytoremediation of contaminated environments. The used experimental design was a completely randomized design with five Cd concentrations (0, 15, 30, 45, and 60 mg L− 1), for 60 days. In general, Cd did not affect nitrate concentration in the root but had a positive effect on leaves. The reduction of nitrate reductase (NR) in plants exposed to Cd was followed by a decrease in ammonia, total soluble amino acids (TSA), and total soluble proteins (TSP). Cd promoted an increase in the concentration of total soluble carbohydrates (TSC), proline, sucrose, and reducing sugars in the plants. The increase in TSC, sucrose and proline, suggests a metabolic regulatory mechanism of V. surinamensis against Cd stress.

“…In fact, a significant positive correlation coefficient (r = 0.784; p = 0.0367) was observed between these variables in plants under Cd, ie the decrease in TSP in V. surinamensis under Cd would be associated with a reduction in NRA. The results obtained in present study in relation the total soluble proteins were evidenced by Anand et al [23].…”

“…When the TSC accumulates, it may contribute to maintaining the plant's water status, favoring tissue protection and physiological processes, an essential mechanism in the tolerance of V. surinamensis to Cd, at least during the experimental period. The total soluble carbohydrate results obtained in this study corroborate with Anand et al (2017).…”

“…This assumption is supported by the signi cant positive correlation coe cient (r = 0.784; p = 0.0367) between these variables in plants under Cd, i.e., the decrease in TSP in V. surinamensis under Cd would be associated with a reduction in NRA. The results obtained herein concerning the total soluble proteins agree with Anand et al (2017).…”
