註釋

Rice genotypes adapted to different edaphic conditions display diverse canopy architectures. To investigate how rice water-deficit adaptability is associated with canopy physiological and morphological characteristics, one irrigated-lowland (cv. IR64) and one aerobic (cv. Apo) rice genotypes were selected from the six rice genotypes based on their similar growth durations but contrasting above-ground architectures. Compared with cv. IR64, cv. Apo allocated less leaf area and less nitrogen to strongly shaded leaves and its leaf angles were less responsive to the long-term water deficit, allowing the vertical nitrogen distribution to better acclimate to light distribution within its canopy. The favourable above-ground architecture and canopy nitrogen profile relative to the light profile contributed greatly to the higher biomass gain and yield in cv. Apo under water deficit.
