Abstract: A breeding method for rapidly stabilizing cotton distant hybridization progeny is disclosed. It belongs to the technical field of plant breeding. The disclosure is based on VSG (G. barbadense semi-compatible material) as female parent, general G. hirsutum materials as male parent of the cross to get F1 generation of G. barbadense-G. hirsutum hybrid materials, and treats the F1 generation of young bolls with 0.03-0.05% of colchicine aqueous solution to induce F2 generation to separate the stable intermediate materials or new varieties with excellent genes of both G. barbadense and G. hirsutum, so as to produce new cotton germplasm resources. The main innovation of the present disclosure lies in that it changes the previous treatment position and method of colchicine on cotton plant, and the disclosure is not limited by haploid and directly treats the cotton bolls on F1 cotton plants.

Abstract: A light modulator (e.g., for terahertz radiation) may be constructed using a prism in which light undergoes total internal reflection (TIR) at one surface. A tunable conductive layer is disposed on the TIR surface. The tunable conductive layer can have a conductivity that is dynamically controllable, e.g., by applying a voltage across the tunable conductive layer or by optically pumping the tunable conductive layer. The tunable conductive layer can absorb a portion of the reflected light beam, attenuating the beam, with the attenuation being a function of the electrical conductivity of the tunable conductive layer. The phase of the reflected light beam can also be altered as a function of electrical conductivity of the tunable conductive layer.
