Methods of seed treatment and resulting products
Provided herein are methods, compositions, and devices relating to administration of UV-B to a seed.
1. A method for improving at least one of plant performance and hardiness, comprising:
administering light enriched for UV-B to a seed, wherein at least 50% of the wavelengths of the administered light comprise UV-B, wherein the seed is treated at a temperature range of about 15° C. to 40° C.; and
bagging the seed for sale.
2. The method of claim 1 , further comprising storing the seed.
3. The method of claim 1 , wherein a wavelength of the UV-B is in a range of about 280 nm to about 290 nm.
4. The method of claim 3 , wherein an irradiance of the UV-B is up to 300 uW cm −2 .
5. The method of claim 3 , wherein an irradiance of the UV-B is more than 300 uW cm −2 .
6. The method of claim 3 , wherein the UV-B is administered at no more than 100 kJ m −2 .
7. The method of claim 1 , wherein a duration of administering the light is in a range of about 1 hour to about 30 hours.
8. The method of claim 1 , wherein the seed is treated at a relative humidity in a range of about 30% to about 100%.
9. The method of claim 1 , wherein a duration of light administration is for less than or at least 60 minutes.
10. The method of claim 1 , wherein a peak wavelength comprises 282 nm.
11. The method of claim 1 , wherein a wavelength of the UV-B is in a range of about 280 nm to about 290 nm, the irradiance is no more than 1.3×10 −4 W cm −2 s −1 , the UV-B is administered at no more than 100 kJ m −2 , and a duration of light administration is for less than or at least 60 minutes.
12. A method for improving at least one of plant performance and hardiness, comprising: administering light enriched for UV-B to a seed wherein at least 50% of the wavelengths of the administered light comprises UV-B, wherein the seed is treated at a temperature range of about 14° C. to 40° C., wherein a wavelength of the UV-B is in a range of about 280 nm to about 290 nm, and wherein an irradiance of the UV-B is more than 300 uW cm −2 .
13. The method of claim 12 , wherein the UV-B is administered at no more than 100 kJ m −2 .
14. The method of claim 12 , wherein the seed is treated at a relative humidity in a range of about 30% to about 100%.
15. The method of claim 12 , wherein a duration of light administration is for less than or at least 60 minutes.
16. A method for improving at least one of plant performance and hardiness, comprising: administering light enriched for UV-B to a seed wherein at least 50% of the wavelengths of the administered light comprises UV-B, wherein the seed is treated at a temperature range of about 14° C. to 40° C., and wherein the seed is treated at a relative humidity in a range of about 30% to about 100%.
17. The method of claim 16 , wherein an irradiance of the UV-B is up to 300 uW cm −2 .
18. The method of claim 16 , wherein an irradiance of the UV-B is more than 300 uW cm −2 .
19. The method of claim 16 , wherein a duration of light administration is for less than or at least 60 minutes.
