Photosynthetic Pigments of Subtropical Plants

Abstract

This chapter concerns the assessment of environmental and varietal affects on photo- synthetic pigment groups. It is revealed that the dynamics of pigment accumulation in subtropical plants within the conditions of Russia’s damp subtropics is a complex pro- cess and depends on species plants. With this in mind, hazelnut maximum green pig- ments were achieved in May, and then in August, there was a decline associated with the onset of short periods of drought and increased temperatures. In Actinidia and tea plants, the highest content of green pigments is achieved in August, which is associated with the biology of these crops. However, regardless of species, with the onset of the dry period (July–August), plants increase their accumulation of carotenoids. The high content of carotenoids that accounts for stress during a period of water availability is evi- dence of their participation in the formation mechanism of subtropical plants’ resistance to
