Redroot pigweed ( amaranthus retroflexus l . ) is an annual species of weeds which is widely distributed and important in cultivated field and other land all over the world 摘要反枝莧是世界性分布的一種惡性雜草, ?解其生物學特性將有助于對其進行有效防治。
On one hand , the growth of spad and the activity of nr had no significant difference at 5 % level . the maximum of soluble sugar content of amaranthus tricolor and bidens maximowiciziana showed significant difference compared with the contrched samples 試驗結果表明,隨著pb處理濃度的增加,各種富集植物的葉片葉綠素值、可溶性糖含量和硝酸還原酶活性表現出相同趨勢,上升后又下降。
Particularly , the activated ratios ( 1 ) of cu and zn in thlaspi goesingense were the highest , which were 2 . 74 % and 3 . 56 % , the activated ratios ( n ) of cd in amaranthus tricolor was the highest , which is 2 . 17 % , but the heavy metals activated ratios of other plants were around 1 . 1 % 其中,羽葉鬼針草對污泥中的cd和zn活化作用比較高,其活化率分別為2 . 17 、 2 . 27 ,僅次于遏藍菜;其次是紫穗槐, zn的活化率為2 . 55 。綠葉莧菜對cd的活化率較高。
The sequence of lead content in each hyperaccumulator was bidens maximowiciziana > amaranthus tricolor > sophora japonica > xanthium sibiricum > schizonepeta fenuifolio > vetiveria zizanioides in this study . on one hand , bidens maximowiciziana and amaranthus tricolor could transport the iiiost of the lead from roots to the above - ground parts , and the total heavy metal translocated ( tmt ) of bidens maximowiciziana and amaranthus tricolor rose to the 11 . 29mg and 9 . 17mg in 100 plants 結果表明,羽葉鬼針草和綠葉莧菜能把吸收的pb較多地運輸到地上部, 100棵羽葉鬼針草和綠葉莧菜地上部的遷移總量高達11 . 29mg和9 . 179mg ;羽葉鬼針草根系對pb的耐性最強,當pb處理濃度為loomg
