Abstract

UV light treatment increases harvested seed yield. UV treatment in combination with chemical treatment also increases seed yield. UV treatment of corn, soybean, and wheat varieties resulted in enhanced harvested seed yield. Hormetic response, disinfection, disinfestations, and other factors are induced by UV treatments.

Claims

exact text as granted — not AI-modified
1 . A method of increasing the yield of harvested plants seeds, the method comprising treating plant sowing seeds with an effective dose of ultraviolet (UV) light. 
     
     
         2 . The method of  claim 1 , wherein the UV light comprises UV-C. 
     
     
         3 . The method of  claim 1 , wherein the UV light is pulsed UV. 
     
     
         4 . The method of  claim 1 , wherein the effective dose range from about 0.025-480 kJ/m 2 . 
     
     
         5 . The method of  claim 3 , wherein the pulsed UV light comprises a high peak power of wavelengths from about 200 to 1100 nm. 
     
     
         6 . The method of  claim 5 , wherein the pulsed UV light is substantially in the UV-C range of 200-280 nm. 
     
     
         7 . The method of  claim 3 , wherein the pulsed UV durations range from picoseconds to microseconds at 1-1900 mJ/cm 2 . 
     
     
         8 . The method of  claim 1 , wherein the harvested plant seed yield increase is by about 5%-10% when compared to yield from harvested untreated control seeds. 
     
     
         9 . The method of  claim 1  further comprising treating the sowing seeds with an agent. 
     
     
         10 . The method of  claim 9 , wherein the agent is selected from the group consisting of pesticides, insecticides, and fungicides. 
     
     
         11 . The method of  claim 1 , wherein the sowing seeds are from a crop plant. 
     
     
         12 . The method of  claim 1 , wherein the plant sowing seeds are selected from the group of plants consisting of soybean, corn, wheat, rice, cotton, sorghum, canola, barley, and vegetable. 
     
     
         13 . The method of  claim 1 , wherein the UV light treatment is applied to the sowing seeds on one side or two sides or the ends or a combination thereof. 
     
     
         14 . The method of  claim 1 , wherein the UV light is from a pulsed laser light source. 
     
     
         15 . A method of treating a plurality of plant sowing seeds with a physical stressor to induce a hormetic response, wherein the physical stressor is UV light and the hormetic response is increased yield of harvested plant seeds. 
     
     
         16 . The method of  claim 15 , wherein the UV light is pulsed. 
     
     
         17 . A plurality of ultraviolet light-treated plant sowing seeds such that the seeds result in plants whose harvested plant seed yield is increased, and wherein the UV light treatment is effective to induce a hormetic response. 
     
     
         18 . The ultraviolet light-treated plant sowing seeds of  claim 17 , wherein the seeds are selected from the group consisting of soybean, corn, wheat, rice, cotton, sorghum, canola and vegetable seeds. 
     
     
         19 . The ultraviolet light-treated plant sowing seeds of  claim 17 , wherein the UV light is pulsed. 
     
     
         20 . The ultraviolet light-treated plant sowing seeds of  claim 17 , wherein the UV light is UV-C with an effective dose range from about 0.025-480 kJ/m 2 . 
     
     
         21 . A plurality of UV-C light-treated sowing plant seeds, wherein the UV-C light is effective to induce an increased yield of the harvested plant seeds. 
     
     
         22 . The plant sowing seeds of  claim 21 , further comprising a treatment with an agent selected from the group consisting of pesticides, insecticides, and fungicides. 
     
     
         23 . The plant sowing seeds of  claim 21 , wherein the seeds are from a crop plant. 
     
     
         24 . The plant sowing seeds of  claim 21 , wherein the plant seeds are selected from the group consisting of soybean, corn, wheat, rice, cotton, sorghum, canola, and barley seeds. 
     
     
         25 . The plant sowing seeds of  claim 21 , wherein the UV-C light comprises an effective dose range from about 0.025-480 kJ/m 2 .
