A special germination box for genetic transformation of large seeds

Abstract

A germination box special for large seed genetic transformation is composed of a box body, a box cover and a carrying bed. The opaque box cover covers the opaque box body to form a black box. A long bar opening is formed in the upper portion of the box cover, and a ventilation assembly is embedded into the long bar opening. The carrying bed comprises a metal wire mesh, cloth and water containing padding, and the metal wire mesh is of a hollow tabulate structure which is formed by metal wires in weaving and shaping modes. A pair of side ears capable of allowing both hands to hold conveniently is fixed on flanges on the two sides of the carrying bed. A cavity of the metal wire mesh is fully filled with the water containing padding, and the cloth is laid on the upper surface of the metal wire mesh. The germination box special for large seed genetic transformation is simple in structure because of only consisting of three components, is beneficial to a full-course sterilizing technology and can be cleaned conveniently. The padding such as quartz sand with good water containing performance is contained in the carrying bed, the common moisture maintaining need can be met, and thus the germination rate and the growth speed of seeds in the box are made to be consistent.

Description

technical field [0001] The invention relates to a tool for seed germination in a laboratory, in particular to a special germination box for large seeds such as corn seeds. Background technique [0002] In a corn breeding laboratory, corn seeds need to be germinated. During the germination process of corn seeds, the following requirements should be met: breathable, sterile, moist and avoid direct soaking. [0003] At present, in the laboratory, the commonly used method is to use a stainless steel fast food box as a germination box. The specific method of use is to lay a layer of filter paper on the bottom of the fast food box. It is more difficult and often wrinkled, which affects the germination rate and growth rate of seeds. Then spread the seeds on the filter paper, pour a certain amount of water into the fast food box, cover the fast food box and place it in a constant temperature and humidity incubator to germinate. [0004] Due to the good sealing performance of the ...
