Embodiment 1

[0053] (a) Cleaning: clean the dirt and impurities on the surface of foxtail seeds with distilled water.

[0054] (b) Dormancy breaking treatment and disinfection: soak in 10% sodium hypochlorite for 24, 48, and 72 hours respectively.

[0055] (c) Rinse: Rinse with sterile water 8 times to wash away the sodium hypochlorite attached to the surface of the Foxtail grass seeds.

[0056]On the basis of the above scheme, the germination test was carried out using the traditional laboratory dish culture method.

[0057] The beneficial effects described in the present invention can be achieved by figure 1 The data in is further reflected.

[0058] figure 1 Among them, the determination cycle of Setaria seed germination rate is 7 days, germination rate = number of germinated seeds / total number of seeds in 7 days; each treatment sets 4 repetitions, and each repetition is 50 seeds; select uniform size, similar color and storage conditions Same batch of seeds.

Embodiment 2

[0060] (a) Cleaning: clean the dirt and impurities on the surface of foxtail seeds with distilled water.

[0061] (b) Dormancy breaking treatment and disinfection: soak in 15% sodium hypochlorite for 24, 48, 72 hours.

[0062] (c) Rinse: Rinse with sterile water 8 times to wash away the sodium hypochlorite attached to the surface of the Foxtail grass seeds.

[0063] On the basis of the above scheme, the germination test was carried out using the traditional laboratory dish culture method.

[0064] The beneficial effects described in the present invention can be achieved by figure 2 The data in is further reflected.

[0065] Note: figure 2 Among them, the determination cycle of Setaria seed germination rate is 7 days, germination rate = number of germinated seeds / total number of seeds in 7 days; each treatment sets 4 repetitions, and each repetition is 50 seeds; select uniform size, similar color and storage conditions Same batch of seeds.

[0066] Known from above data,...

Abstract

The invention discloses a method for improving the germination rate of seeds of Setaria viridis. The seeds of the Setaria viridis are soaked in 10% sodium hypochlorite solution for 48 hours or in 15%sodium hypochlorite solution for 24 hours, so that the germination rate of the seeds of the Setaria viridis can be obviously improved, the highest germination rate can reach 97%, and the rate is increased by 81.83%-93.33%. According to the method, the bacterial infection of a seed material of the Setaria viridis can also be effectively avoided, the dual effects of disinfection and breaking of dormancy can be achieved, and a basis is provided for future development of the Setaria viridis serving as a novel C4 model plant.

Description

technical field [0001] The invention belongs to the field of agricultural biotechnology, and relates to a method for improving the germination rate of foxtail seeds. Background technique [0002] Setaria is an annual herb of the Poaceae Setaria genus, which reproduces by selfing seeds and has universal dormancy characteristics. In recent years, with the development of the field of plant life science, Setaria, as a new type of C4 model, has attracted the attention of many scientific researchers. Compared with other C4 model plants, it has the advantages of short plant, short growth cycle, many offspring, easy survival, easy mutation, small genome and clear gene sequence; and, Setaria is compatible with many grass crops, such as millet, corn, etc. , has a relatively close genetic relationship, and has a unique advantage in studying the photosynthesis mechanism of C4 plants. [0003] In April 2017, in the journal Nature Plants, the researchers used Setaria as a model plant to...
