Abstract

Iris halophila is an ornamental flower species distributed in arid regions, the germination percentage of its seeds is low, which causes a difficulty in its breeding, and the landscape application of this plant is severely constrained. The purpose of this study was to understand the dormancy of I. halophila seeds through conducting the absorbent and germination experiments. The results revealed that 25/10 ℃ was the most suitable temperature for germination of I. halophila seeds, and a germination rate of 44.33% was attained; it was considered that the germination inhibitory substances in endosperm may be the main factor restricting the germination of I. halophila seeds; seed coat may mechanically restrict the release of inhibitory substances in endosperm; the seed germination percentage could be increased through scarification and removal of endosperm and GA3, and scarification would be the best way of improving the germination of I. halophila seeds.

Key words： Iris halophila; ornamental plant species; seed dormancy; seed germination
