Compared with natural seeds, artificial seeds obtained by tissue culture technology have the following advantages:
1. The replication speed is fast and the structure is complete.
2. Different components of "seed coat" can be configured according to the growth needs of different plants.
3. In terms of mass propagation and artificial afforestation of seedlings, artificial seeds can reduce the cost more than the propagation method of test-tube seedlings, and it is convenient for mechanized sowing and can save labor.
4. Somatic embryos are produced by asexual reproduction system, so hybrids can be fixed.
5. Sometimes some pesticides, bacterial fertilizers, beneficial microorganisms, hormones, etc. It can be added to artificial seeds, which has better nutrition supply and disease resistance, thus obtaining the possibility of more vigorous growth.
6. The way of embryoid development can be used as a bridge between genetic engineering and higher plant genetic engineering.
7. The problems of poor reproductive ability, difficult seed setting or low germination rate of some crop varieties were solved.
8. It is possible to cultivate new varieties faster without seasonal restrictions.
9. It can completely maintain the genetic characteristics of fine varieties, and the production is not limited by seasons.
10. The size is consistent, the seeds are evenly sown and the seedlings are neat.
1 1. It is convenient for storage and transportation.
12. The medium used has the characteristics of small quantity, small volume, rapid propagation, rapid germination and seedling formation, and convenient transportation and storage.
13. Artificial seed technology is suitable for the propagation of rare tree species with difficult preservation of germplasm resources, unstable genetic traits or poor fertility.
14. Artificial seeds can overcome the virus accumulation caused by asexual reproduction and can quickly propagate virus-free seedlings.
