Inoculation with Azospirillum brasilense Cd of two leguminous species, soybean (Glycine max) and cowpea (Vigna unguiculata), demonstrated that: (1) A. brasilense significantly increased proton efflux from their roots; (2) inoculation reduced plant membrane potential (in soybean), (3) inoculation changed the phospholipid quantity in plant membranes of calli(More)
INTRODUCTION Ultraviolet type C (UV-C) radiation has higher energy than the UV-B radiation and has been less studied because it is completely absorbed by the ozone layer. However, artificial UV-C radiation can generate diverse modifications in the plants. Given that exposure to UV-C for short periods of time increases the antioxidant content, improving the(More)
Experiments were performed to determine optimal conditions for callus induction and plantlet regeneration from damiana (Turnera diffusa, Willd.) leaf explants. MS media [7] and B5 media [4] were used; both of them were supplemented with different combinations of 2,4-dichlorophenoxyacetic, acid (2,4-D) and 6-benzyl-adenine (BA). In all cases the samples were(More)
Tissue culture propagation was performed on the spice shrub damiana (Turnera diffusa. Willd.) using MS medium (Murashige and Skoog 1962) supplemented with different combinations of the plant growth regulators, 6-benzyl adenine (BA) and indole-3-butyric acid (IBA). Organogenesis of leaf explants from wild plants and explants from propagated cuttings was(More)
Plants of damiana(Turnera diffusa Willd.) are important to industry and traditional medicine in semi-arid climates. Although all populations are wild, no reports have been made previously of their different phenotypes. Here, we investigated various micromorphological characteristics and the levels of essential oils in two phenotypes. Oils were extracted(More)
Callus and cell suspension cultures of cowpea (Vigna unguiculata) were induced with 2,4-dichlorophenoxyacetic acid and grown at different NaCl concentrations. The cell biomass yield and its total lipid content decreased with increasing salinity. However, while the hexose content in lipids was higher, the amount of lipid phosphorus was significantly lower in(More)
In order to evaluate their responses to drought, we determined the photosynthetic activity water potential, stomatal conductance, transpiration, water use efficiency photosynthetic photon flux density and leaf temperature of Paulownia imperialis, P. fortunei and P. elongata in three different soil moisture conditions in the field. Our results showed that P.(More)
Damiana is a medicinal plant with many traditional uses and a reputation as an aphrodisiac. Essential oils produced by this plant are used in traditional medicine, and for the preparation of liquors and tea. The composition of essential oils from wild damiana, plants grown with micropropagated methods involving cell suspension, and explants in solid medium,(More)
Salinity is an unfavourable factor to plant growth, development, and quality because high salinity increases oxidative stress and damage in plants. Damiana (Turnera diffusa Willd.) plants grow in arid zones. They are socio-economically important as they have industrial potential. Currently, no reports on their tolerance to salinity are available. This study(More)
