The influence of natural light intensity on the seed germination of the yellow-fruited form of Psidium cattleianum Afzel. ex Sabine was studied in the greenhouse complex conditions of Donetsk Botanical Garden. It was found that maximum germination (44.1 %) is achieved under full illumination (3882.4± 235.9 lx). 50 % reduction in light intensity significantly reduces germination by 14.4 %. The results proved the positive photoblastism of seeds and the importance of optimal light regime for the species propagation.
