Pinacea oleracea seeds obtained from a local farmer had been planted using standard procedures on a cultivated arable land in mid tropical summer period in the months of June and July, 2016 in Ede, semi urban western Nigeria. The growth pattern of Pinacea oleracea has been studied via the infrared remote sensing of notable solar-induced physiological parameters of the canopy from germination to flowering stage. The physiological parameters observed were Canopy Reflectance at panchromatic wavelengths, Fluorescence, Fluorescence Intensity, Chlorophyll luminescence, leaf surface Moisture and temperatures. Measurements were taken 6 hourly every day for five days, at Germination, onset of Foliage and Flowering stages. Results showed that the spectral responses varied with cloud covers, time and sunshine hours of the day. Though slightly low at germination results also indicated that solar-induced canopy reflectance increased with the onset of foliage and became fairly sinusoidal at the flowering stage. Results further showed that Canopy Reflectance and fluorescence intensity as well as chlorophyll luminescence exhibited some degradation with time.
