The leaves of succulent Crassula multicava growing in greenhouse conditions showed disease symptoms, yellow and gradually browning spots, and the disease was caused by Pestalotia sp. In the excised healthy leaves of Crassula multicava kept in natural or inverted position in natural light conditions the accumulation of red-violet anthocyanins were formed but in the excised leaves with disease symptoms caused by Pestalotia sp. kept in the same light conditions anthocyanins did not form at a distance of about 4-8 mm from infected spots. The possible mechanism of anthocyanins accumulation in the excised healthy leaves of Crassula multicava in light and the lack of anthocyanins accumulation around the infected spots caused by Pestalotia sp. is discussed.
