Germination of seeds of five cultivars of Echinochloa colonum (L.) link in response to potassium nitrate and white light of varying photon flux density and photoperiod

摘要: Single seed lots of each five cultivars the minor millet Echinochloa colonum (L.) Link (common name shama or jungle rice), produced under similar conditions, were tested for germination 10 days in an alternating-temperature regime 20°C/30°C (16/8 hours) with and without 0.2% potassium nitrate solution co-applied darkness white fluorescent light different photon flux area densities applied daily durations
