Problems solved by technology

Studies have shown that there are substances that inhibit seed germination in the iron-clad gold pulp, pericarp, seed coat, and seed embryo, and there are physical and physiological dormancy at the same time, which makes it difficult to germinate.
[0003] At present, the use of concentrated sulfuric acid or gibberellin in existing technologies can help break its dormancy characteristics and improve germination potential, but concentrated sulfuric acid is difficult to obtain in actual production, and there are risks and safety problems in operation, so it is not suitable to use
It takes about a week for iron-coated gold seeds to germinate without treatment, and the germination is extremely irregular, with a time span of more than 35 days, which has a great adverse effect on the actual artificial seedling cultivation
Although the existing technology uses 500 mg / L gibberellin to increase the germination potential (statistical germination potential on the 15th day) to about 48%, and the germination rate to 66%, but the time required for germination is still long, and the uniformity of germination is also low. It needs to be improved. For farmers, it is not convenient to configure a certain concentration of gibberellin in actual production.

Embodiment 1

[0027] 1. Select purple-black iron-coated gold-free fruits (do not pick green to red fruits, which are all immature fruits, and the seeds in fruits in this growth stage are not fully developed, which will affect normal germination).

[0028] The iron-clad gold seed that embodiment 1 adopts is Berchemia lineata The mature fruit of (L.)DC. was used for seeding.

[0029] 2. Rub the fruit picked in step ⑴ while it is fresh, peel off the skin and flesh, and rinse off the residual flesh and juice attached to the seeds with clean water.

[0030] 3. With 0.3%KMnO 4 Solution Soak the seeds treated in step (2) for 30 min for disinfection, and rinse them with clean water.

[0031] 4. Use the sterilized (simple method: put the fine sand into water and boil for more than 25 minutes) and then mix the cooled wet sand with the seeds treated in step (3). The sand humidity is required to be 50%~90%, and the volume ratio of seeds to sand is between 1:3~1:5.

[0032] 5. Put the mixture of see...

Embodiment 2

[0035] The method and iron-coated gold seeds are the same as in Example 1, except that the refrigerated time in step (5) is 90 days.

Embodiment 3

[0037] The method and iron-coated gold seeds are the same as in Example 1, except that the refrigerating time in step (5) is 120 days.

Abstract

The invention provides a method for breaking dormancy and promoting germination of berchemia lineata seeds. The method comprises the following steps of: S1, picking mature berchemia lineata fruits, and obtaining seeds; S2, mixing the berchemia lineata seeds obtained in S1 with wet sand uniformly and refrigerating the mixture; and S3, taking out the mixture refrigerated in S2, and implementing germination and seedling. According to the method provided by the invention, and the seeds start to germinate in the third day, the germination rate within a week can reach about 85%; and at the tenth day, the germination basically ends, and the germination rate can reach 90%. The method provided by the invention is easy in material acquisition, easy and safe in operation, low in cost, and suitable for artificial seedling for broad general farmers, thus providing an important technical support for the realization of artificial propagation of berchemia lineata.

Description

technical field [0001] The invention belongs to the technical field of iron-clad gold seed cultivation methods, and more specifically relates to a method for breaking dormancy and promoting germination of iron-clad gold seeds. Background technique [0002] Iron-clad gold, the original plant is Rhamnaceae plant iron-clad gold Berchemia lineata (L.)DC. or Guangzhigoucatecha B. polyphylla Wall var .leioclada Handel-Mazzetti, mostly used as medicine with dried roots or stems, is a commonly used national medicine. In recent years, due to the discovery that iron-clad gold has good curative effects in many aspects such as anti-inflammatory, analgesic, antibacterial, liver protection, and anti-tumor, it has been more and more developed and utilized, and its market demand has increased significantly. At present, the source of iron-clad gold medicinal materials is basically wild excavation, and the resource reserves are gradually decreasing. There are few genuine iron-clad gold ...
