• Manipulating Crop Row Orientation to Suppress Weeds and Increase Crop Yield (2010, background): “Photosynthetically active radiation (PAR) was also measured at the late-flowering stage of crops (i.e., just before biomass assessment) at midday on a sunny day at the center of the crop row space with a linear ceptometer1 (Pearcy 1991).”
• Estimation of leaf area index in eucalypt forest with vertical foliage, using cover and fullframe fisheye photography (2007, unknown): “Hence, the first aim of this study was to answer the questions ‘‘Can L be reliably predicted from foliage cover in vertical leaved forest’’ and ‘‘What is k at the zenith in such forest?’’ An apparent advantage of hemispherical or fisheye methods, which measure the gap fraction at more than one zenit”
• Seasonal changes in photoprotective mechanisms of leaves from shaded and unshaded field-grown coffee (Coffea arabica L.) trees (2008, methodology): “The PAR intercepted by an individual leaf was estimated using azimuth and elevation angle of the sun, the solar declination at the sampling dates, in addition to leaf inclination and leaf azimuth angles (Pearcy 1989).”
• Seasonal patterns in post-dispersal seed predation of Abutilon theophrasti and Setaria faberi in three cropping systems (2006, methodology): “For each sampling period, three 15second measurements of photosynthetically active radiation (PAR) were collected below and above the canopy in each plot between 10:00 and 14:00 (Pearcy 1991).”
• Sources of errors in measurements of PAR (2000, methodology): “Following mass production of quantum sensors LI-190SA (silicon photodiode covered with a visible bandpass interference filter and a coloured glass filter) by LI-COR (LI-COR, 1986; 1991) use of quantum sensors has been rapidly expanded (e.g. Norman et al., 1969; Britton and Dodd, 1976; Howell et al.,”
