Abstract:
Taking violet as the test material,the effects of different concentrations of aluminum stress (0,5,10,20,40 mmol·L-1) on the seed germination and physiological characteristics of violet seedlings were studied by using the filter paper method and pot experiment methods,in order to provide a reference for revealing the physiological mechanism of violet seeds and seedlings in response to aluminum stress.The results showed that with the increase of aluminum ion concentration，the germination potential，germination rate，maximum root length，stalk height，crown width，stem diameter，leaf number，shoot fresh weight and dry weight，root fresh weight and dry weight were significantly decreased.The activity of peroxidase (POD) in seedling leaves increased first and then decreased with the increase of aluminum ion concentration.The activity of superoxide dismutase (SOD) and the content of malondialdehyde (MDA) increased with the increase of aluminum ion concentration.When the aluminum ion concentration reached 20 mmol·L-1，the POD activity of seedling leaves reached the maximum.When the aluminum ion concentration reached 40 mmol·L-1，the SOD activity and MDA content of seedling leaves reached the maximum，which seriously inhibited the growth of violet seedlings.Violet has strong tolerance to aluminum toxicity，which can be used for landscaping in industrial and mining areas or acidic soil areas with aluminum ion concentration lower than 40 mmol·L-1.
