fruit quality - Opis:
- Physalis peruviana is one of the most promising tropical fruit plants because of its rapid growth, high yield, and nutritional quality. Th is study was designed to investigate plant development under heavy metal contamination (Cd, Pb) and responsiveness to arbuscular mycorrhizal fungi (AMF) colonization by Rhizophagus clarum and Claroideoglomus claroideum. Th e antioxidant capacity, total lipid content and fatty acid profi le in fruits, accumulation of Cd and Pb in diff erent plant parts, plant dry biomass, and mycorrhizal colonization were determined. As a result of inoculation, a considerable reduction in Cd and Pb in the fruits was observed, compared with non-inoculated plants. Th e fruit number and dry weight increased in plants associated with C. claroideum. Th ese plants also showed higher acid phosphatase activity, root protein accumulation and glomalin production. Th e type of antioxidant defense was AMF strain-dependent. Antioxidant activity and H2O2 neutralization were enzymatic rather than non-enzymatic processes in the fruits of C. claroideum plants compared with those forming an association with R. clarum. Mycorrhizal establishment changed the composition and concentration of fruits’ fatty acids. Th e ratio of unsaturated fatty acids was increased. With respect to the accumulation of bioactive compounds in golden berry the present fi ndings are important for obtaining the optimum benefi ts of mycorrhizal association under unfavorable conditions.
