1. Experiments on the seed germination of some palms (Butia capitata, Phoenix canariensis and Washingtonia robusta) were carried out. Germinations of Phoemix canariensis seeds and Washingtonia seeds are easy, but that of Butia capitata seeds shows a little difficulty caused by the dormancy or some other inhibiting factors.
2. The optimum temperature and days required for germination are 30°C and about 60 days in Butia capitata, 30-35°C and about 20 days in Phoenix canariensis, and 25-35°C and 8 days in Washingtonia robusta, respectively.
3. Sand and vermiculite are better for Phoenix and Washigtonia while clayey soil is preferable for Butia as the germination bed.
4. There are some differences in the morphological and anatomical structures of seeds among the species experimented. Therefore the process of germination must vary depending on the species. The germination of Washingtonia robusta seeds is easy as the structure of its seed is simple like that of cereal seed.
