Embodiment 1

[0021] Put the selected Xantho sorbifolium seeds in 80°C distilled water for 10 minutes, take out the seeds and rinse them with distilled water for 3 times, then place them in 3 times the river sand, keep the river sand moist, and then store the seeds in a constant temperature environment at 25°C Accelerate the germination and stir once a day, the germination rate of the sorbifolium sorbifolium seeds is 58.30% after 11 days, and the germination rate of the seeds after 12 days is 60.00%. The germination potential of the seeds was 52.5%.

Embodiment 2

[0023] Put the selected sorbiflora seeds in 80°C distilled water for 15 minutes, take out the seeds and rinse them with distilled water for 4 times, then place them in 3 times the river sand, keep the river sand moist, and then store the seeds in a constant temperature environment at 25°C Accelerate the germination and stir once a day, the germination rate of the sorbifolium sorbifolium seeds is 55.83% after 10 days, and the germination rate of the seeds after 12 days is 58.83%. The germination potential of the seeds is 51.83%

Embodiment 3

[0025] Put the selected Xantho sorbifolium seeds in 80°C distilled water for 12 minutes, take out the seeds and rinse them with distilled water for 3 times, then place them in 3 times the river sand, keep the river sand moist, and then store the seeds in a constant temperature environment at 25°C Accelerate the germination and turn it once a day, the germination rate of the sorbifolium sorbifolium seeds is 58.30% after 10 days, 59.83% after 11 days, and 60.00% after 12 days. The germination potential of the seeds was 53.50%. Example 4

Abstract

The invention provides a germination accelerating method for rapidly relieving dormancy of xanthoceras sorbifolia seeds, belonging to the technical field of seed treatment. The method comprises the following steps of carrying out constant-temperature water bath on xanthoceras sorbifolia seeds in distilled water with the temperature of 70-85 DEG C for 10-15 minutes within 10-12 days before sowing; and taking out the xanthoceras sorbifolia seeds, flushing the xanthoceras sorbifolia seeds with distilled water for 2-3 times, placing the xanthoceras sorbifolia seeds into river sand, and storing the seeds at the temperature of 20-25 DEG C to accelerate germination for 10-12 days. Compared with the prior art, the germination accelerating method has the advantages that not only is the germination time of the xanthoceras sorbifolia seeds effectively shortened, but also the germination rate and germination potential of xanthoceras sorbifolia are remarkably increased, the germination rate of the xanthoceras sorbifolia seeds is about 60%, the germination potential of the xanthoceras sorbifolia seeds is higher than 52%, the high germination accelerating speed is achieved, and the germination accelerating effect of xanthoceras sorbifolia and the evenness of young seedlings obtained after the xanthoceras sorbifolia seeds germinate are improved to great extent. The method is few in limiting condition, convenient to operate, capable of effectively reducing the cost and increasing the production efficiency and suitable for large-scale production. The germination accelerating method has guiding significance on increasing the germination rate of the xanthoceras sorbifolia seeds and popularizing and planting the xanthoceras sorbifolia seeds on a large area.

Description

technical field [0001] The invention relates to a germination accelerating method for rapidly relieving dormancy of sorbiflora sorbifolium seeds, and belongs to the technical field of seed treatment. Background technique [0002] Xanthocerassorbifolia Bunge belongs to Sapindaceae (Sapindaceae) Xanthoceras Bunge. It is a unique woody oil tree species in my country. The characteristics of drought tolerance and salt tolerance have great development prospects in the vast northern regions of China and the alpine mountainous regions in the south. However, the long dormant period of X. sorbifolium seeds results in a very low natural germination rate of X. sorbifolium seeds, which seriously hinders the large-scale promotion and planting of X. sorbifolium, a tree species with both ecological and economic value. [0003] The low germination rate and long germination time of X. sorbifolium seeds are caused by the deep dormancy of seeds, which brings huge losses to agricultural and fore...
