摘要: AbstractSpatial and temporal variations of photosynthetic photon flux density (PFD) measured using small photodiodes (Hamamatsu, model G1118) attached on the leaf surface rice (Oryza sativa L.) differed with orientation inclination even at same height canopy. Under sunny conditions, fluctuation pattern PFD was mainly determined by surface, not daily change in open, e. g., high peaks were observed morning east-oriented leaves, but only low north-oriented leaves. overcast however, depended highly open irrespective inclination. The present study suggests that should be considered as major factors influencing regime (spatial variation total PFD) within To determine effects spatial crop prod...
