Abstract:
With cucumber ‘Lyuyou Fourth’ as test material，effect of different concentration of ionic liquids（0，5，10，15，20，25，30 mg/L）1-hexyl-3-methyl imidazole bromide salts([C6mim]Br)influence on seed germination，seedling morphology，physiological and biochemical characteristics of leaf were studied.The results showed that ionic liquid [C6mim]Br reduced the cucumber seed germination rate and germination potential in different levels,decreased the seedling root and stem length，reduced proline (Pro) and chlorophyll content of seedling leaf，and the above inhibitory effect should have the characteristics of a typical dose dependent.With the ionic liquid [C6mim]Br concentration increased，superoxide dismutase (SOD) and peroxidase (POD) vitality in cucumber seedling leaves all increased at first then decreased.Echoing each other at a distance，superoxide anion radicals (O?[TX-*4]2) production rate and malondialdehyde (MDA) content decreased at first and then rose.Low concentration of [C6mim]Br could start stress protective reaction of protective enzyme system，alleviate the ionic liquid [C6mim]Br’s toxic effects in a certain degree，but its ability to regulate was limited，when the concentration of ionic liquids>15 mg/L of ionic liquids，with the increase of ionic liquid concentration，protective enzyme vigor declined intensively.
