Abstract: In order to improve the winter corms reproduction methods of gladiolus in South China, reproductive experiments were conducted by using different size of gladiolus cormels and different sowing density. Results showed that the size of gladiolus corms harvested was affected by the size of sowing cormels and sowing density. When the circumference of sowing gladiolus cormels was 2.3—3.1 cm, and the sowing density was 400 grain·m-2, the numbers of commercial corms (circumference >6 cm) and cormels were the largest (255 grain·m-2 and 9813 grain·m-2). When the circumference of sowing gladiolus cormels was 2.3—3.1 cm, and the sowing density was 200 grain·m-2, the percentage of harvested commercial corms were the highest, upto 76.38%.
