Abstract
Rapid pulse programming of a seed, to obtain improved germination probability, and increased root mass, and crop yield, by illuminating the seed with radiation of a wavelength distribution from 300 nm to 20 microns, with a minimum average irradiance of 0.2 Watts/cm2 and a maximum average irradiance of 7 Watts/cm2, and having a narrow specific range of cumulative illumination energy from ½ Joules/cm2 to 3 Joules/cm2 or a higher transition point cumulative illumination energy, so as to specifically engage an irradiance-sensitive and energy-sensitive hidden stimulative exposure response in the seed and so as to avoid illumination of higher cumulative illumination energy that would cause a different and destructive exposure response in the seed. Preferred wavelengths include one or both of Medium Wavelength Infrared (MWIR) radiation and an Indigo Region Illumination Distribution (IRID), which may be applied to an illuminated agricultural planter.
