Problems solved by technology

[0004] However, the germination rate of E. elongatum seeds was only about 75% under natural (25°C) conditions for 7 days, and the germination rate could be increased to 81.5% at most if the time was prolonged.
It takes 9 days for the treatment of variable temperature 10℃~20℃ (low temperature 16h + high temperature 8h cycle) to reach a germination rate of 91.5%. high-quality development of the industry

Embodiment 1

[0028] The present embodiment provides a method for promoting the germination of E. elongatum seeds, comprising the following steps:

[0029] Select the seeds of Echinopsis elongatum with full grain and uniform texture, disinfect them with 5% sodium hypochlorite for 20 minutes, and rinse them with distilled water;

[0030] Place the sterilized and rinsed Thiopyrum elongatum seeds in a petri dish with double-layer filter paper, and add gibberellin GA with a concentration of 1500mg / L 3 solution in which the seeds are soaked, and then loaded with seeds and gibberellin GA 3 The petri dish of the solution was placed at a constant temperature of 25° C., and cultured alternately under light (2500 lx) for 16 hours and in darkness for 8 hours.

[0031] The above treatment was repeated 5 times, and 50 seeds were repeated each time. Add an appropriate amount of culture solution of the same concentration to the seeds every day, and turn over the seedlings with sterilized tweezers when t...

Embodiment 2

[0034] The present embodiment provides a method for promoting the germination of E. elongatum seeds, comprising the following steps:

[0035] Select the seeds of Echinopsis elongatum with full grain and uniform texture, disinfect them with 5% sodium hypochlorite for 20 minutes, and rinse them with distilled water;

[0036] Place the sterilized and rinsed Thiopyrum elongatum seeds in a petri dish with double-layer filter paper, and add gibberellin GA with a concentration of 1000mg / L 3 solution in which the seeds are soaked, and then loaded with seeds and gibberellin GA 3 The petri dish of the solution was placed at a constant temperature of 25° C., and cultured alternately under light (2500 lx) for 16 hours and in darkness for 8 hours.

[0037] The above treatment was repeated 5 times, and 50 seeds were repeated each time. All the other operations are the same as in Example 1.

[0038] In the present embodiment, on the 7th day, the seed germination rate was 89.67%.

Abstract

The invention provides a method for accelerating an elytrigia elongata seed to sprout. The method comprises the following steps of: culturing the elytrigia elongata seed under a condition of 25 DEG Cand 6h illumination / 8h darkness, and meanwhile, carrying out gibberellin GA3 processing, wherein the concentration of the gibberellin GA3 is 1000-1500 mg / L. According to the method provided by the invention, through a combined function of a proper temperature, illumination and the gibberellin of the specific concentration, the germination rate of the elytrigia elongata seed is improved, the germination efficiency of the elytrigia elongata seed is greatly improved, and the germination rate can be 96.67% only in seven days. The method disclosed by the invention is simple to operate, is easy tomaster, and can provide important technical guidance for realizing the large-scale normalized planting of the artificial grassland of the elytrigia elongata.

Description

technical field [0001] The invention relates to the technical field of plant seed germination, and more specifically, relates to a method for promoting germination of Etypyronium elongatum seeds. Background technique [0002] Elytrigia elongata (Elytrigia elongata) is a perennial rhizome herb of the genus Elytrigia in the Triticeae family Poaceae. It has strong drought and salt tolerance and is one of the ideal herb plants for improving saline-alkali land. One, also a relative of wheat (Triticum aestivum), has become an indispensable wild gene pool for improved wheat. It is native to southern Europe and Aria Minor, and is currently planted in the warm regions of western North America. After being introduced in my country, it is planted on the saline-alkali land in the north (Xinjiang, Inner Mongolia, Gansu and other provinces) and the eastern coast. It is an excellent forage grass in the region and can be used as an ideal grass species for ecological environment construction...
