Embodiment 1

[0021] A method for improving the germination rate of forsythia seeds, specifically comprising the following steps:

[0022] S1, using the water precipitation method to select forsythia seeds with full particles and shiny seed coats, soak the seeds in an aqueous solution of potassium permanganate for 2 hours, then remove them, rinse them with pure water for several times until the residual potassium permanganate solution is cleaned, and obtain Soak the seeds, 50 seeds are processed each time during the soaking process, and three groups of repetitions are established;

[0023] S2, soaking the soaked seeds obtained in S1 in a gibberellin solution with a concentration of 100 mg / L for 8 hours to obtain the seeds to be germinated;

[0024] S3, placing the seed to be germinated obtained in S2 on the bud bed, then putting it into a culture container and cultivating it for 12 days under the culture conditions of 12 hours of light and 12 hours of darkness in the photoperiod;

[0025] ...

Embodiment 2

[0027] The specific steps of the method provided in Example 2 and Example 1 are the same, the only difference is that in step S2, the soaking time is 4 hours.

Embodiment 3

[0029] The specific steps of the method provided in embodiment 3 and embodiment 1 are the same, the only difference is that in step S2, the soaking time is 12h.

Abstract

The invention discloses a method capable of increasing forsythia seed germination rate. The method includes following steps: S1, selecting forsythia seeds with full grains and glossy seed skin, adopting a potassium permanganate water solution to soak the seeds for 1-3h, fishing out, and washing to obtain soaked seeds; S2, soaking the soaked seeds obtained in the S1 into a gibberellin solution of 50-200mg / L for 4-24h to obtain seeds waiting for germination; S3, putting the seeds waiting for germination obtained in the S2 onto a germination bed, and putting into a culture container for culture for 11-13d at temperature of 20-30 DEG C in an illumination condition and 15-25 DEG C in a dark condition, wherein a light cycle is 12h of illumination and 12h of darkness. The method can greatly increase forsythia seed germination vigor and germination rate, seed germination rate can reach 91.33%, and germination period is shortened; the method is simple in operation, low in cost, time-saving andlabor-saving.

Description

technical field [0001] The invention belongs to the technical field of planting, and in particular relates to a method for improving the germination rate of forsythia seeds. Background technique [0002] Forsythia is a plant of the Oleaceae Forsythia genus, which has extremely high utilization value and development prospects. Forsythia is a traditional Chinese medicinal material commonly used in my country, and it is also one of the "five major commercial medicines" in China. It can be used as medicine all over the body. The flower color is golden, it has the characteristics of a long flowering period and a large number of flowers. It is an important early spring flower viewing plant in northern my country. It is widely used in landscaping and can also be used as one of the fresh cut flowers. It has a very high ornamental value. Due to the high economic value of forsythia, people over-harvest wild forsythia, and the wild area of ​​forsythia decreases sharply, resulting in sh...
