“…Ascorbate peroxidase (APX) activity was measured according to Nakano and Asada (1981) with modification as in Spanò et al (2011a). Enzyme activity was assayed from the decrease in absorbance at 290 nm (extinction coefficient 2.8 mM −1 cm −1 ) as ascorbate was oxidized and the unit of activity was expressed as micromole of ascorbic acid oxidized min –1 .…”

The Mediterranean basin is characterised by increasingly dry summers and the study of the adaptive traits developed by plants living in this stressful environment is of great interest, also in relation to climate projections for this area.Cistus monspeliensis, Myrtus communis and Phillyrea angustifolia are three co-occurring shrubs typical of the Mediterranean maquis. Their functional and physiological parameters were studied in spring, summer and autumn in order to highlight adjustments of these traits and to test eventual different adaptive strategies.Soil and leaf chemical characteristics were determined in the different seasons. Leaf area, specific leaf area, leaf dry matter content, succulence index, pigment contents hydric status and main markers of oxidative stress and antioxidant response were detected.The stressful summer season induced disturbance in hydric balance, decrease in succulence index and chlorophyll content and high contents of hydrogen peroxide. Thanks to higher enzymatic activities and total glutathione content, in the two evergreen species M. communis and P. angustifolia oxidative damage remained at levels equal to or lower than the other seasons. Only in the semideciduous C. monspeliensis both functional and biochemical traits showed a higher stress condition in summer. The higher stability of functional traits in the two evergreen species may be explained by the sclerophyllous nature of their leaves. Four environmental variables – Tmax, Tmin, soil conductivity and organic matter – mostly influenced NMDS segregation of these species.

“…The lower germination presented by Núcleo Bandeirante accession after the desiccation is probably due to the fact of its greater sensitivity to desiccation. According Spanó et al (2011) [28] different protective mechanisms seem to act in combination but their relative importance changes as maturation progresses and in response to the drying method. There was formation of normal seedlings, with well-developed root and shoots and with no apparent damage at 60 days of in vitro culture in both accessions.…”

“…Tolerance to dehydration varies from species to species and among tissues of the same plant, and appropriate humidity must be reached to ensure adequate survival of the material [22]. Besides that, desiccation tolerance is directly related to changes in cellular components, to the activation of antioxidant enzyme systems, to oligosaccharides and to heat-resistant proteins [3,8,28].…”

RESUMO:Objetivou-se, com essa pesquisa, realizar a classificação quanto a tolerância à dessecação e a capacidade de armazenamento de sementes de cinco espécies florestais de matas ciliares da bacia do Alto Rio Grande, no Estado de Minas Gerias. SEED STORAGE BEHAVIOR OF FOREST TREE SPECIES SEEDSABSTRACT: Seeds of five forest species were classified according to their physiological storage behavior. Seeds of Casearia sylvestris Swart (Salicaceae), Qualea grandiflora Mart. (Vochysiaceae), Guarea kunthiana A. Juss. (Meliaceae), Eremanthus incanus Less. (Asteraceae), Protium heptaphyllum March. (Burseraceae) were collected and taken to the laboratory, where they were processed and submitted to both rapid and slow drying, storage and assayed for viability. After physiological classification regarding storage behavior, it was observed that seeds of C. sylvestris and E. incanus presented orthodox behavior. Seeds of G. kunthiana and P. heptaphyllum were classified as recalcitrant and Q. grandiflora as an intermediate, which did not tolerate low moisture content.
