Effect of osmopriming on Dormancy Break and Germination Parameters of Fritillaria imperialis Seed
Abstract:   (396 Views)

Fritillaria imperialis is one of the valuable medicinal and ecotourism species in Zagros region. While germination and establishment of this plant are problematic, seed priming may increase germination capacity of this plant. This research was designed in two separate experiments. First experiment was done to find the effects of osmopriming on dormancy break of seed as factorial in randomized complete block design with 4 replicate. Experimental factors included duration of stratification (4 and 8 weeks), osmotic potential created with PEG (-3, -6, -9 and -12 bar), and duration of priming (12, 24, 36 and 48 hours). The results showed that potential of -12 bar during 12h and 8 weeks stratification affected germination percentage, germination rate, length of seedling and vigor index (Ι and II) significantly but were not effective in reducing the need for stratification. The second experiment was conducted to study effects of osmotic potential and priming duration on improving germination traits after breaking dormancy. According to data analysis, effect of potential and priming duration on all of the mentioned traits were significant and improved.
