英文摘要: 

        The soluble protein content of damaged leaves of six kinds of cruciferous vegetables was measured by staining with Coomassie brilliant blue G-250 The results show that there were different influences on the soluble protein content of leaves damaged by Phyllotreta striolata(F) The soluble protein content of leaves of Raphanus sativusBrassica chinensis andB parachinensis was significantly higher than that of the control ( P 0. 05 ) after having been fed on byP striolatafor 8 d and 10 d Similar changes in soluble protein were detected inB oleracea after10 dand12 dandinB juncea and

B alboglabraafter 12 dThere washoweverno significant difference ( P 0. 05 ) in the soluble protein content ofB juncea leaves that had been fed on byP striolata for2 dprobably because of this speciesgreater insect resistance The soluble protein content of cruciferous vegetable leaves decreased after they had been fed on byP striolata for 212 daysThis may be a plant defense mechanism or a response to insect attack
