Photosynthesis and photosynthetic metabolism of carbon in different variety of leguminous plants under conditions of drought
In this article experimental data on the influence of soil drought on the intensity of potential photosynthesis (IPPh) and photosynthetic metabolism of carbon in the leaves of different varieties of leguminous plants in the flowering phase are presents. It was shown that in all explored objects the content of the glycolate pathway intermediates (GPI) in the experimental plants was higher than in the control plants. The inclusion of carbon 14C in PHEP-carboxylation products, including malate, also has this tendency. In general, it was found that the change in the studied parameters of intensity of potential photosynthesis and the photosynthetic metabolism of carbon depending on the effects of soil drought may be due to the mechanism of physiological and biochemical adaptation of plants to these stressful conditions.
