Problems solved by technology

At present, there is no report on the seed germination system of Baihuashan grape. Therefore, we collected the seeds of Baihuashan grape at the end of 2018, explored a seed germination system with a high emergence rate of this species, and invented a Baihuashan grape seed germination technology for the first time

Embodiment 1

[0024] Collect fresh and ripe Baihuashan grapes in early September, put the whole bunch into mesh bags, and store them in a 4°C refrigerator for 1 month. At the beginning of October, take out the fruit, soak the fruit with water at room temperature until the peel becomes soft, remove the peel, wash the obtained seeds, select the plump seeds with water, and use filter paper to absorb the moisture on the surface of the seeds. The seeds were treated in the gibberellin solution of 0, 100, 500, 1000, 1500, 2000, 2500 and 3000 mg / L for 12, 24, 36 and 48 hours respectively (that is, the concentration of the gibberellin solution and the treatment time as a variable to conduct orthogonal experiments), and then placed on 4 layers of completely wet gauze (humidity of 60%), controlling the germination temperature to 25°C, and germinating in the dark, during which the humidity of the gauze was checked every morning and evening, and the germination was carried out. Moisturizing spray.

Embodiment 2

[0027] Collect fresh and ripe Baihuashan grapes in early September, put the whole bunch into mesh bags, and store them in a 4°C refrigerator for 1 month. At the beginning of October, take out the fruit, soak the fruit with water at room temperature until the peel becomes soft, remove the peel, wash the obtained seeds, select the plump seeds with water, and use filter paper to absorb the moisture on the surface of the seeds. The seeds are mixed with 3 times the volume of wet fine sand (humidity is 60%) and then loaded into the mesh belt, buried in the fine sand with humidity of 60% for sand storage stratification, the sand storage depth is 5cm, and the sand storage temperature is Store in the sand at 4°C for 3 months, check the humidity of the fine sand every 3 days, and spray for moisturizing. At the beginning of January, take out the seeds after being stored in the sand, wash them with water, mix the seeds with 3 times the volume of wet vermiculite (humidity is 60%) and place...

Abstract

The invention discloses a Vitis amurensis seed germination method, which comprises: taking mature Vitis amurensis fruits, placing in a refrigerator, storing for 1 month, soaking with clear water, removing the peel, and selecting full seeds for spare; the seeds are subjected to sand storage and stratification for 3 months and then germinate in darkness in a vermiculite matrix with the humidity of 60%, the germination temperature is 25 DEG C, and spraying is carried out for moisturizing in the germination period. According to the method disclosed by the invention, the germination system of the special wild plant, namely the Baihua vitis amurensis in China and the II-level key protection in Beijing is established for the first time, the noninvasive propagation of the Baihua vitis amurensis is realized, the seedling raising problem in the Baihua vitis amurensis population reconstruction process is effectively solved, and a good foundation is provided for increasing the individual number of the Baihua vitis amurensis and realizing long-term continuation of the Baihua vitis amurensis.

Description

technical field [0001] The invention belongs to biological cultivation technology, and in particular relates to a method for germination of Baihuashan grape seeds and its application. Background technique [0002] Vitis baihuashanensis (Vitis baihuashanensis) is a woody vine belonging to the Vitis family Vitis genus. It is a special product in North China and an endangered species only found in the northwest mountainous area of ​​Beijing. According to reports and field investigations, the number of wild individuals of this species was less than 20 in 1994, and has dropped sharply to 2 in 2016, and the growth conditions of these 2 wild individuals are deteriorating. Although the Baihuashan grape is listed as a Class II key protected wild plant in Beijing, its endangered status has not been fully paid attention to. Since the publication of this species, little is known about the morphological characteristics and survival status of the Baihuashan grape. At present, only tissue ...
