Physiological changes of seedlings inoculated with spp. under drought stress.

Tree regeneration is significantly affected by water deficiency, which could be alleviated by the inoculation of spp In this study, the effects of rhizosphere inoculation with spp on the antioxidant system and osmotic substances in the seedlings of was investigated under experimental drought stresses, with the relative water content 50%-60%, 35%-50%, and 20%-35% as the light, moderate and severe drought stress, respectively. The results showed that, with increasing drought stress, the activities of protective enzymes, SOD and POD in the needles of seedlings were significantly promoted, the contents of MDA and proline were remarkably increased, whereas the contents of soluble protein and starch showed a decreasing trend. Inoculation with spp promoted much stronger increase in the activities of SOD and POD in the needles, yet the MDA content showed a lower level of increase.

Intensity-modulating graphene metamaterial for multiband terahertz absorption.

In this paper, we design a tunable strength multiband absorber consisting of a graphene metamaterial structure and a thick dielectric interlayer deposited on a metal ground plane. We investigate the tunable conductivity properties of the graphene metamaterial and demonstrate multiband absorbers with three absorption bands using a polyimide interlayer in the 0-2.25 THz range by numerical simulation.
