Embodiment 1
[0019] Embodiment 1 The inventive method
[0020] Main instrument of the present invention: artificial climate chamber (RGX-250)
[0021] The present invention is a kind of method that improves the germination rate of dianthus chinensis seeds, and it is carried out according to the following steps:
[0022] (1) Drying in the shade with the peel, the collected ripe fruits of Chonglou Dianchi are dried in the shade with the peel (in terms of mass fraction, dry in the shade until the water content is 29-31%).
[0023] (2) Remove the outer testa by rubbing off the outer seed coat of the seeds that have been dried in the shade with the peel. (You can rub off the outer testa to cool the water slightly, and dry it in a room without direct sunlight, and then store it in a seed bag for later use).
[0024] (3) Soak in high temperature, soak the seeds with the outer testa rubbed off in 40°C water for 48 hours.
[0025] (4) Seed coat damage treatment, after soaking the seeds in high t...
Embodiment 2
[0028] Embodiment 2 Seeds with pericarp dry in the shade and without pericarp dry in the shade compare
[0029] Embodiment 2 is by changing the single factor of drying in the shade with the peel and drying in the shade without the peel, and comparing its influence on the germination rate of the seeds of Chonglou. This embodiment carries out two treatments of drying in the shade with the peel and drying in the shade without the peel. The steps are the same as in Example 1, except that the dried fruit of the fruit is dried in the shade without the peel, and the remaining steps are the same as in Example 1, except that the collected ripe fruits of P.
[0030] The results of the experiment showed (see Table 1 for details): the germination rate of P. chinensis seeds was 96%±3% when the peel was dried in the shade (method A), and the germination rate of the seeds was 87% without drying in the shade (method B). %±2%.
Embodiment 3
[0031] Embodiment 3 high temperature water immersion compares with not carrying out high temperature water immersion
[0032] Embodiment 3 is by changing 40 ℃ high temperature water immersion and not carrying out the single factor of high temperature water immersion, compares its influence on the germination rate of the seeds of P. Any immersion) two treatments, the steps of 40°C high temperature water immersion treatment are the same as in Example 1, except that step (3) high temperature water immersion in Example 1 is omitted, other steps are the same as in Example 1 without high temperature water immersion treatment .
[0033] The experimental results showed (see Table 1 for details): the germination rate of the seeds of P. chinensis was 96%±3% when soaked in high-temperature water at 40°C (method A); the germination rate of the seeds of P. chinensis was 96%±3% without high-temperature water immersion (method B). The rate is 80%±4%.
