萌发植物金莲花的生长和镉的积累。通过盆栽试验研究了嫁接在4种陆生十字花科树种砧木上的插条。将药用白菜实生苗的接穗嫁接到小白菜、萝卜、甘蓝型油菜和大白菜的砧木上。H·哈拉。1个月后采穗，在Cd污染土壤(10mgCd kg-1)中生长60d。与未嫁接的药用植物相比，嫁接在萝卜和甘蓝型油菜上的嫁接提高了药用植物插条的根、地上部和全株生物量。甘蓝型油菜砧木比大蒜砧木更有利于提高药用油菜插穗的生物量。与未嫁接的药用植物相比，四种砧木对药用植物的光合色素含量降低或没有显著影响。只有嫁接在甘蓝型油菜砧木上才能提高抗氧化酶活性。与未嫁接的药用植物相比，大蒜和甘蓝型油菜的砧木降低了药用植物插条根部和地上部的Cd含量，而其他砧木对地上部Cd含量的影响不显著。4种砧木对药用地锦插穗提取Cd的影响不明显。因此，嫁接后修剪并不能提高药用植物在Cd污染土壤中生长的修复能力。然而，萝卜和甘蓝型油菜的砧木降低了药用植物插穗中Cd的含量，这为药用植物在Cd污染土壤中作为野生蔬菜的安全生产提供了潜在的途径。
The growth and cadmium (Cd) accumulation of emergent plant Nasturtium officinale R. Br. cuttings taken from plants grafted onto rootstocks of four terrestrial Cruciferae species were studied in a pot experiment. Scions from N. officinale seedlings were grafted onto rootstocks of Brassica chinensis L., Raphanus sativus L., Brassica napus L., and Rorippa dubia (Pers.) H. Hara. Cuttings were taken after 1 month and grown in Cd-contaminated soil (10 mg Cd kg-1) for 60 days. Compared with non-grafted N. officinale, grafting onto R. sativus and B. napus rootstocks increased the root, shoot, and whole plant biomasses of N. officinale cuttings. Brassica napus rootstock was more effective than R. sativus rootstock for increasing the biomass of N. officinale cuttings. The four rootstocks decreased or had no significant effect on photosynthetic pigment contents in N. officinale cuttings compared with non-grafted N. officinale. Only grafting onto B. napus rootstock enhanced antioxidant enzyme activities. Compared with non-grafted N. officinale, R. sativus and B. napus rootstocks decreased the Cd contents in roots and shoots of N. officinale cuttings, whereas the other rootstocks had no significant effect on the shoot Cd content. The four rootstocks had no increase effects on Cd extraction by N. officinale cuttings. Therefore, cutting after grafting did not enhance the phytoremediation ability of N. officinale for growth in Cd-contaminated soil. However, R. sativus and B. napus rootstocks decreased the Cd content in N. officinale cuttings, which offers a potential approach for N. officinale safety production as a wild vegetable in Cd-contaminated soils.
