Embodiment 1
[0034] Example 1: ARTP treatment test of Chang 7-2 corn variety
[0035] (1) Select 750 Chang 7-2 corn seeds with plump and complete grains and a moisture content of 15-17%, and divide them into 15 portions on average, 50 grains in each portion.
[0036] (2) ARTP processing. The above-mentioned 15 parts of dry seeds are processed by the ARTP generating device, and the corn seeds are neatly placed in the carrier tray suitable for larger plant seeds of the plant-type ARTP generating device during processing, preferably ensuring that each seed is an embryo. Upward, which is conducive to improving the efficiency of ARTP treatment. With 99.99% helium as the working gas, the working pressure is ambient atmospheric pressure, and the working temperature is 30°C. The power supply is 400W, the working air flow rate is 15L / min, and the plasma emission source and The distance between the corn seeds was 2-5mm, the treatment time was divided into five levels of 0, 30, 60, 90 and 120min, an...
Embodiment 2
[0048] In order to further study the change of seed germination rate after ARTP short-term treatment, for the corn seeds of the new DH variety, the same operation method and calculation method as in Example 1 were adopted, except that the treatment time was three times: 0, 5, and 10min. Level, the germination rate of this variety is obtained, which is recorded in Table 2.
[0049] Table 2 Statistical table of seed germination rate
[0050]
[0051] As can be seen from Table 2, for the corn seeds of the new DH variety, the treatment time is divided into 0, 5, and 10min, and the germination rate is in a declining mode. Therefore, at least after ARTP treatment, the germination rate decreases, which is beneficial Storage of corn seeds.
Embodiment 3
[0052] Embodiment 3: PH4CV corn seed ARTP treatment test under different conditions
[0053] (1) Selection. 900 PH4CV corn seeds with plump and complete grains and a water content of 15-17% were taken, and the experiment was designed according to random blocks, and each treatment group was repeated three times.
[0054] (2) Seed treatment. ①Dried seeds: Treat according to step (3), the treatment time is three levels of 0, 15 and 30 minutes, each treatment group is repeated three times, and each repetition is 50 seeds. ② Wet seeds: Soak in water for 12 hours at 25°C, and then treat according to step (3). The treatment time is 0, 15 and 30 minutes, and each treatment group is repeated three times, with 50 seeds in each repetition.
[0055] (3) ARTP processing. The seeds in (2) are processed by the ARTP generator, with 99.99% helium as the working gas, the working pressure is ambient atmospheric pressure, the working temperature is 30°C, the power supply is 380W, the working a...
