High-efficient pregermination method of pyracantha fortuneana seeds

Abstract

The invention discloses a high-efficient pregermination method of pyracantha fortuneana seeds. The method comprises the following steps: selecting mature pyracantha fortuneana fruits as the pyracantha fortuneana seeds; putting the pyracantha fortuneana seeds into a plastic bag and then sealing; performing pregermination until a white part of buds is exposed and then comes out through anaerobic fermentation; elutriating with clean water; removing fruit flesh; soaking with clean water subjected to aeration for 24 hours for one day; taking out and draining; sowing into soil or seedbed for conventional young seedling cultivating. The high-efficient pregermination method disclosed by the invention has the advantages that seed embryos are difficult to damage, the germination rate is high, the cost is low, the efficiency is high, the labor strength is small and the germination cost is low.

Description

technical field [0001] The invention relates to a method for accelerating germination, in particular to a method for accelerating germination of firethorn seeds with high efficiency. Background technique [0002] Pyracantha forluneana, also known as torch fruit, rescue food, Qinling Begonia, etc., belongs to the genus Pyracantha of the family Rosaceae, and is mainly produced in Shaanxi, Jiangsu, Fujian, Hubei, Guangxi, Sichuan, Yunnan, Guizhou and other places. Typical native plants The tree species has strong adaptability, resistance to thin knots, drought resistance, pruning resistance, rapid growth, easy molding, lush branches and leaves, dense white flowers in early summer, numerous red fruits in autumn and long fruit-hanging time. It has high ornamental value and can be used in large quantities. Landscaping of factories, cities and roads and restoration of rocky desert vegetation. [0003] At present, the propagation of Pyracantha mainly includes three methods: seed pr...

Problems solved by technology

Generally speaking, cutting propagation is mostly used for plants with a low degree of lignification, such as ball orchid, gloxinia, gerbera, etc. Plants with a higher degree of lignification are used less and are not easy to succeed, such as grapes, pine trees, etc.; The cutting degree is high, the cuttings are not easy to survive, and the survival rate of the cuttings is affected by the season, temperature and moisture, and the survival rate is low when the management is not good.

The layering propagation technique is more difficult, and the source of seedlings is limited, it is not easy to form large-scale and factory production, and it is generally not favored by people; the processing technology of seed propagation is less difficult, and the seedlings grow fast and vigorously, but Pyracantha seeds are coated with horny and Germination is slow, the emergence speed is slow and uneven, and there is currently no method for accelerating the germination of mature Pyracantha seeds

At present, when pretreatment methods are used to treat Pyracantha seeds, seed soaking in concentrated sulfuric acid, soaking seeds in warm soup, gibberellin and other treatment methods are commonly used to increase the germination rate of seeds. However, this kind of operation is easy to cause damage to the seed embryo, and has the characteristics of low germination rate, high cost, low efficiency, high labor intensity, high germination cost, etc., and it is time-consuming and laborious, which brings great difficulty to large-scale Pyracantha seedlings , increasing the cost of Pyracantha seedlings

[0004] Therefore, the existing Pyracantha germination method has the disadvantages of easy damage to the seed embryo, low germination rate, high cost, low efficiency, high labor intensity, and high germination cost.
