Title: Effects of different treatments on seed germination of Mentha rotundifolia
Abstract: Objective To evaluate the seed morphology of Mentha rotundifolia and the effect of different treatments on seed germination,and to provide a scientific basis for seeding and artificial cultivation of M.rotundifolia.Methods Length and width for seed and weight of one thousand seeds were measured and seed germination percentages were recorded and analyzed statistically,through setting conditions including different culture temperatures,different light qualities,and soaking treatment with different concentration of GA3/KNO3.Results The seed morphology in M.rotundifolia is oval with(1.77 ± 0.01) mm of length and(1.13 ± 0.01) mm of width.The weight of one thousand seeds is(1 175.5 ± 21.02) mg and the weight after seed absorbing water is about 8.8 times more than seed dry weight.The optimal temperature is 30 ℃ for seed germination;Seed germination could be affected under different light qualities and full darkness conditions.White light was the most conductive to seed germination,but full darkness was the least conductive.After soaking treatment with GA3/0.25% KNO3,not only seed germination percentage could be significantly promoted,but also germination index and vigor index were affected.Conclusion The suitable condition for seed germination in M.rotundifolia is gained through this research,which will provide important guiding reference for seeding and artificial cultivation of M.rotundifolia.
