Nonenzymatic antioxidants

Among the oysters, P. eous recorded highest levels of non-enzymatic antioxidative substances. Total glutathione content was significantly very high in P. eous, followed by P. sajor-caju, P. flabellatus and H. ulmarius. High level of total phenols, flavanoids, lycopene total carotenoid and vitamin A were recorded in P. eous. This was followed by P. sajor-caju, P. flabellatus and H. ulmarius. There was no significant difference in vitamin C content among the oyster mushrooms.

A study was conducted to investigate the effects of paclobutrazol (PBZ) (1.25 g a.i m-1 ) on the contents of non-enzymatic antioxidants, ascorbic acid, glutathione (GSH) and phenols and activities of antioxidant enzymes, peroxidase, catalase, superoxide dismutase and ascorbate peroxidase in buds and leaves of growing shoots of mango cv. Totapuri at four distinct phenological stages numerically represented as 510 (initiation of bud swelling), 511 (Swollen buds, 513 (bud burst) and 515 (panicle emergence) as per BBCH scale.

A field experiment was conducted to study the response of antioxidant enzymes to oxidative damage caused by heat stress induced by changing dates of transplanting in two rice (Oryza sativa L.) genotypes viz., ‘N22’ (heat tolerant) and ‘IR8’ (heat susceptible). During grain filling period, constitutive level of antioxidative enzymes viz., superoxide dismutase, catalase, ascorbate peroxidase, was found to be 35.7, 88.8 and 84.1% higher respectively, while the content of non-enzymatic antioxidants viz., ascorbate and proline was 78.5 and 81.

The mechanism of tolerance to high temperatures was investigated in two strawberry (Fragaria × ananassa Duch) cultivars, ‘Redlands Hope’ (‘R. Hope’, heat tolerant) and ‘Cal. Giant 3’ (‘CG3’, heat sensitive). Leaves were collected from plants that were exposed to gradual heat stress and heat-shock stress separately.
