Abstract:
With Lythrum salicaria Linn and Iris pseudacorus Lridaceae as test materials，the study was carried out to determine the germination ability of the seeds of Lythrum salicaria Linn and Iris pseudacorus Lridaceae.The experiment set different mass concentrations gradient of salt solution which were 0，2 500，5 000，10 000，15 000 mg/L，to deal with the seeds respectively.And the seed germination rate，germination energy，germination index，and vigor index were measured under salt stress.The results showed that the germination rate，germination energy，germination index，and vigor index of seeds of Lythrum salicaria Linn and Iris pseudacorus Lridaceae had declined with the increase of salt concentration.The indicators of the seed of experiment data demonstrated that the degree of decline of Lythrum salicaria Linn was lower than that of Iris pseudacorus Lridaceae.The root of Lythrum salicaria Linn of salt sensitivity was greater than the shoot，and the shoot of Iris pseudacorus Lridaceae of salt sensitivity was greater than root，at the beginning of the seed germination.
