采用200～400mg·L^-1多效唑(PP333)和1000～2000mg·L^-1矮壮素(CCC)对处于生长中期的2个彩色马蹄莲(Zantedeschia antedeschia)盆栽品种进行矮化处理,结果显示彩色马蹄莲的株型明显矮化,茎杆增粗。统计分析表明:PP333处理的矮化效果较明显,其中以300mg·L^-1效果最佳,说明PP333对设施栽培条件下彩色马蹄莲的防徒长、抗倒伏的矮化处理有实用价值。

Using 200-400 mg·L^{- 1} PP333and 1 000- 2 000 mg·L^-1 CCC on two cultivars of potted Zantedeschia antedeschia, the heights of them were obviously dwarfed after one month sprayed weekly, and the plant stems grew thickly. The results of statistic analysis show that PP333is more effective than CCC in dwarf culture, and the optimum concentration of PP333is 300 mg·L^{- 1}. It suggests that PP333has applied value in dwarfing treatments of Z. antedeschia under facilities-cultivation.
