Abstract:
Taking mature Impatiens balsamina L.seeds as test materials，the effects of SA under NaCl stress on the indexes such as the germination vigor，germination rate，germination index，the average radicle length and average hypocotyl length were determined.In addition，such indexes as soluble sugar，soluble protein and malondialdehyde (MDA) contents of the seedlings were also measured.The results showed that SA treatment caused significant effects on the germination indexes of the seeds and the physiological indexes of the seedlings.The seeds treated by SA at the concentration of 50 mg/L had the most significant increases in all indexes.MDA content in the seedlings decreased to the minimum value 50 mg/L SA could effectively alleviate the damages of salt stress to the seeds and seedlings of Impatiens balsamina L.and promote the salt resistance of the seeds and seedlings.
