An efficient procedure for shoot regeneration was obtained by endosperm culture in Actinidia deliciosa cv. Hayward. Mature endosperm cultured on MS medium supplemented with 2 mg/l 2,4-D and 5 mg/l kinetin developed callus with 80% efficiency. Callus was transferred on MS medium containing different plant growth regulators (2,4-D, TDZ, IAA, NAA, BAP, kinetin, 2iP) for regeneration. There were si...
Aminopeptidase (AP) activity in ripe but firm fruit of Actinidia deliciosa was characterized using L-leucine-p-nitroanilide as a substrate. The enzyme activity was the highest under alkaline conditions and was thermolabile. EDTA, 1,10-phenanthroline, iodoacetamide, and Zn(2+) had inhibitory effect while a low concentration of dithiothreitol (DTT) had stimulatory effect on kiwifruit AP activity....
Evidence exists to suggest that melatonin (MT) is important to abiotic stress tolerance in plants. Here, we investigated whether exogenous MT reduces heat damage on biological parameters and gene expression in kiwifruit (Actinidia deliciosa) seedlings. Pretreatment with MT alleviates heat-induced oxidative harm through reducing H₂O₂ content and increasing proline content. Moreover, MT applicati...
The antioxidant potential of Actinidia macrosperma C. F. Liang (Actinidiaceae) was investigated in vitro for total phenolic content, along with total antioxidant activity (TAA), 1,1-diphenyl 2-picryl hydrazyl (DPPH), and lipid peroxidation (LP). The results indicated that different polarity extracts of A. macrosperma exhibit different biological activities, which depends mainly on the presence ...
