摘要
将获得的8株耐重金属菌株与苗龄为5 d的水稻植株同时置于1/2 MS培养基上共培养,7 d后统计水稻(Oryza sativa)生物学性状。结果表明,菌株3与水稻共培养后,株高、根长与对照之间无差异,但根数和鲜重与对照差异显著。菌株39与水稻共培养后,株高、根长、鲜重与对照无差异,但根数与对照差异显著。其他菌株与水稻共培养后,株高、根长、鲜重、根数与对照差异显著,尤其是菌株52对水稻生长负面影响最大。
Eight heavy metal resistant strains and rice（Oryza sativa）plants with seedling age of 5 days were co-cultured in 1 / 2Ms. Biological character of rice was analyzed after 7 days. Rice co-cultured with strain 3 showed no difference with the control in plant height and root length but significant difference in fresh weight and root number. Rice co-cultured with strain 39 showed no difference with the contrast in plant height, root length and fresh weight but significant difference in root number.Rice co-cultured with other strains exhibited no difference with the contrast in the 4 biological characters. But strain 52 has the most negative effect on the growth of rice.
