The results suggested that the activities of these enzymes quickly enhanced at 1 d, 3 d, 5 d and 7 d after inoculation by injecting conidia of the false smut fungus at 7-10 d before heading in the resistant cultivars, but slower increase in the susceptible cultivars, and also showed that there was correlations between the cultivar resistance to the disease and the three enzymes.

结果表明，在抗病品种中苯丙氨酸解氨酶、过氧化物酶和多酚氧化酶3种酶活性接种后迅速提高，变化幅度较大；而感病品种的酶活性在接种后缓慢增加，变化幅度小。由此说明，这3种防御酶与水稻抗稻曲病有一定的关系。关键词水稻；稻曲病；防御酶

Among transformed plants of cabbage and cauliflower, there were several transgenic lines having club root disease resistance.
