The understory evergreen trees showed maximal photosynthetic capacity in winter, while the overstory deciduous trees showed this capacity in spring. The time lag in productive ecophysiologically active periods between deciduous overstory and evergreen understory trees in a common temperate forest was clearly related to the amount of overstory foliage.

In remote sensing, many spectral indices such as NDVI (Normalized Difference Vegetation Index) or NDWI (Normalized Difference Water Index) have been developed for plant management in agriculture. However an essential problem exists that the remote sensing indices are not based theoretically on the spectral properties of the molecules of photosynthetic(More)
