Seed Morphology and Germination of Native Tulipa Species

چکیده
Seeds are important for the preservation and reproduction of wild tulips in situ, but only a few studies have been carried out on their seed morphology germination characteristics. In this study, eight tulip species native to China were used. Their superficial ornamentation, relationship between germination, effects manipulating incubation temperature, coat, gibberellin (GA3) application studied. The seeds diverse shape, size, color, weight, as observed by stereomicroscopy scanning electron microscopy. Tulipa edulis (Miq.) Baker had half-moon-shaped with embryo invisible irregular striped which was different from other seven that sector-shaped visible reticulate ornamentation. Especially, muri feature decorative pattern meshes highly variable decisive at both section levels L. We also classified dormancy type nondeep complex (MPD). Embryo length, embryo/seed length ratio, coat color correlated (T50), while T50 still mainly affected optimized temperatures 4 °C and/or 4/16 °C. Gibberellin has positive regulating effect species, 100 ?M considered most effective concentration. These results highlight taxonomic significance genus based testa morphology, we support notion T. should be regarded an independent genus—Amana. Meanwhile, our study provided way could shortened within 2 months under experimental conditions, will help rapidly multiply utilize resources.
