摘要
The effect of seed density on the germination of 2 columnar Cactus species (Isolatocereus (dumortieri and Myrtillocactus geometrizans) was evaluated using 5 seed density treatments (1, 5, 10, 20 and 50 seeds). Isolatocereus dumortieri had a lower germination percentage with increasing seed density; germination of M. geometrizans was not affected by seed density. These results suggest that I. dumortieri seedlings might compete for resources with siblings.
