ABSTRACT
Red leaves may increase the productivity of plants in horticulture due to the involvement of antocyanes in photosynthesis. More often red colour is inherited as a dominant or not completely dominant trait. For red peaches the scheme of Gregor Mendel was approved. In Fj all peaches were red, in F2 the ratio of green plants to red plants obtained was 1:3 and by genotype 1:2.1. The spectral characteristic of red plants supporting the idea is that antocyanes enhanced light absorption at wavelength 380-370 run. From analysis of data for cultivars Red Haven (green leaf) and Negus (red leaf), the absorption of latter is much stronger at light waves 400-470. Negus showed a 42.5% increase in absorption at 430 nm compared to Red Haven. Light absorption intensity in red leaf exceeded absorption in green leaf by 8-10% at 400 - 710 nm.
