| Popis: | The article substantiates the feasibility of studying the issue of seed germination of iris species under conditions of introduction. The viability of iris seeds from the subgenus Limniris (Iris ensataThunb.,Iris pseudacorusL.,Iris sanguineaDonn ex Hornem.,Iris setosaPall. ex Link,Iris versicolorL.) andXyridion(Iris carthaliniaeFomin,Iris gramineaL.,Iris orientalisThunb.) was estimated during long-term storage. Morphological and biological parameters of experimental seeds were descripted. The literature data on fast and one-time germination of seeds in representatives of the subgenusLimniriswas confirmed. The seeds of this group began to germinate after 21-36 days from sowing them in pots. In theXyridiongroup, seedlings appear after 2-4 months. The shortest period of seed germination (30 days) was observed forIris pseudacorus, the longest (2 years 7 months) - forIris graminea. The germination of iris seeds in moist habitats (subgenusLimniris) lasts for 4-6, the steppe species (subgenusXyridion) - 9-11 years. |
