Abstract:
Seeds of ‘Jinyou 35’ cucumber (Cucumis sativus L.) were inoculated with or without arbuscular mycorrhizal fungus (AMF) Glomus versiforme,then cucumber seedlings treated with 0,0.50,0.75,1.00,1.25,1.50 mmol?L-1 salicylic acid (SA) to investigate effects of the different chilling treatments (day/night temperature 12 ℃/5 ℃) on chilling resistance of cucumber plants.The results showed that inoculation with G.versiforme,comparing with the non-inoculation,significantly increased root activities,contents of leaf chlorophyll,soluble sugar and proteins and decreased membrane permeability and methane dicarboxylic aldehyde content under the treatment with the same concentration of SA.Treatment with 1.00 mmol?L-1 of SA and with G.versiforme inoculation showed the best beneficial effects in increasing chilling resistance of cucumber plants.It was suggested that the combination treatment with the SA application and AMF inoculation had potential in improving cucumber production in winter protective cultivation.
