摘要: The gas chromatography-mass spectrometry (GC-MS) analysis revealed that the composition of root exudates released by grafted eggplants differed not only from the non-grafted eggplants but also from the tomato rootstock plants. Ten chemical classes were isolated and identified in root exudates of grafted eggplants. The effects of benzyl benzoate identified in root exudates of grafted eggplant were determined at 0.05 to 4.0 mmol.L-1 concentrations on seed germination and seedling growth of eggplant. The benzyl benzoate stimulated the seed germination and seedling growth of eggplant. However, benzyl benzoate inhibited the malondialdehyde (MDA) content 0.05 to 1 mmol.L-1., but stimulated it >0.5 mmol.L-1. POD activities were enhanced in all treatments. The PAL activities were higher than control (CK) from 0.05 to 0.1 mmol.L-1, but lower than CK from 0.5 to 4.0 mmol.L-1.
