The crisp melon seeds of example 2 were treated by the pretreatment method before germination, and the soaking times of 0, 6, 9, and 12 hours for the hydrolysis-resistant stable ion titanium aqueous solution were respectively set for two changing factors of 0, 5, 7, and 10mg/L titanium ion concentration.
Timely observing the germination condition of seeds, recording the germination vigor of the seeds after 1d, recording the germination rate, radicle length and embryo axis length of the seeds after 3d, sowing the seeds in a plug tray at proper time, observing the growth vigor of plants after 30d according to the conventional management of seedling culture, and recording the growth index. The test was randomly bagged for use at 200 seeds per serving and repeated 3 times. The results of the implementation are shown in tables 1 and 2.
TABLE 1 influence of treatments with different seed soaking time and different hydrolysis resistance stabilizing ion titanium concentrations on seed germination of melon
TABLE 2 influence of treatments with different seed soaking time and different hydrolysis-resistant stable ion titanium concentrations on melon seedling growth
The result shows that the treatment method has obvious promotion effect on germination indexes such as germination rate, germination potential, radicle length, hypocotyl length and the like of the crisp melon seeds, and has good influence on seedling growth vigor such as root length, fresh weight, leaf area and strong seedling index, especially has uniform growth vigor, and the axial length of the three-day embryo can reach more proper 13-17 mm, can avoid overgrowth lodging in later stage, and is pleasant to see in seedling production. Wherein the combination of soaking seed for 9h and stabilizing ion titanium concentration for hydrolysis resistance of 7mg/L is optimal.
Test three
Influence of different illumination conditions on germination and seedling growth of melon seeds
The melon seeds of example 2 were treated for S5 XS 2 by the pretreatment method, and red light irradiation was performed for 24 hours, blue light irradiation was performed for 24 hours, and the germination accelerating light condition changing factor was set for 24 hours.
Based on example 2, the titanium ion concentration was changed to 0mg/L, the germination accelerating conditions were changed to 24 hours under dark conditions, and other conditions were unchanged, to serve as a control group.
Timely observing the germination condition of seeds, recording the germination vigor of the seeds after 1d, recording the germination rate, radicle length and embryo axis length of the seeds after 3d, sowing the seeds in a plug tray at proper time, observing the growth vigor of plants after 30d according to the conventional management of seedling culture, and recording the growth index. The test was randomly bagged for use at 200 seeds per serving and repeated 3 times. The results of the implementation are shown in tables 3 and 4.
TABLE 3 influence of different illumination conditions on seed germination of melon
| Illumination conditions | Germination percentage/100% | Germination potential/100% | Radicle length/mm | Embryo axial length/mm |
| Red light irradiation for 24 hours | 98.00 | 94.50 | 28.60 | 16.80 |
| Blue light irradiation for 24 hours | 99.00 | 95.33 | 31.50 | 14.28 |
| Light-shielding for 24 hours | 96.00 | 90.67 | 24.00 | 11.60 |
| Control group | 80.30 | 73.00 | 21.50 | 10.28 |
TABLE 4 influence of different illumination conditions on melon seedling growth
| Illumination conditions | Root length/mm | Fresh weight/g | Leaf area/mm 2 | Index of strong seedlings |
| Red light irradiation for 24 hours | 12.89 | 7.69 | 2200 | 9.2 |
| Blue light irradiation for 24 hours | 16.57 | 7.81 | 2055 | 9.5 |
| Light-shielding for 24 hours | 11.91 | 6.14 | 1915 | 9.0 |
| Control group | 10.89 | 6.02 | 1818 | 7.4 |
The result shows that the red and blue light irradiation can improve the germination condition and seedling growth vigor of the melon seeds to different degrees, wherein the red light can promote the growth and development of the overground parts of plants, the blue light can promote the growth of the underground parts of the plants, and the stem node overgrowth is inhibited. The red and blue light irradiation and hydrolysis resistant stable ionic titanium aqueous solution treatment can promote seed germination and also can play a role in preventing high-foot lodging in the seedling stage of crisp melon.
