Abstract

The invention relates to a method for simplifying saving of a seedless grape embryo, which is achieved by saving an in vitro embryo of the seedless grape embryo and comprises the following steps: preparing a synthetic medium, selecting and sterilizing young fruit, carrying out isolated culturing on the ovule, embryo stripping and embryo culture; selecting seed abortion seedless grape young fruit 72 days after flower blooming, washing the young fruit and sterilizing the young fruit at a clean bench respectively by corrosive sublimate and alcohol and stripping the ovule under aseptic conditions; then, inoculating the young fruit on the synthetic medium for carrying out dark culture, wherein the pH value of culture medium is 5.8-6.2 and culture temperature is 25-30 DEG C; carrying out embryostripping treatment on the ovule after the ovule is cultured for 40-60 days; and continuing to inoculate the ovule to the synthetic medium and carrying out illumination culture on the ovule for 2000-4000LX. When the illumination culture is carried out on the ovule for 20-30 days, then embryo begins to germinate, a radicle gradually grows at the lower part of the embryo and two cotyledons gradually grown at the upper part of the embryo and finally the seedling is obtained. According to the method in the invention, a growth culture medium, a germination culture medium and a seedling formation culture medium are integrated into a whole and the saving of the seedless grape embryo is simplified and accelerated.

Description

technical field [0001] The invention relates to a method for simplifying seedless grape embryo rescue, which effectively simplifies the cultivation steps and accelerates the seedling formation process. Background technique [0002] Embryo rescue technology is to prepare a medium-the composition is similar to the nutrients supplied by the surrounding tissues in the embryo sac environment, and carry out in vitro culture before the abortion of zygotic embryos, so that the embryos that are about to be aborted continue to develop, and finally germinate into a complete embryo. plants. This technology realizes seedless plants that cannot be obtained by conventional cross-breeding. Since Haberlandt put forward the hypothesis of plant cell "totipotency" based on cell theory in 1902, plant embryo culture has developed rapidly. In 1904, Hanning successfully used the embryos of radish and horseradish for the first time to do systematic plant embryo culture on artificial medium. In 19...
