摘要:
以1个耐低磷和1个低磷敏感水稻为材料，通过土培试验研究磷、砷双重胁迫对水稻苗期生物学特性及磷、砷吸收的影响，并比较不同品种之间的差异. 结果表明，相同磷水平下，外加砷浓度为小于25 mg/kg时，水稻的生物量、叶宽、株高、SPAD值及磷吸收量均随砷浓度的增加而增加，当砷浓度达到50 mg/kg时开始下降，两个品种表现相同趋势. 说明少量砷可以刺激水稻生长，促进磷的吸收，砷用量过多则抑制水稻的生长及磷的吸收. 相同砷水平下，水稻生物学性状及磷、砷吸收量随磷用量的增加而增加，两个品种亦表现相同趋势. 说明适当施磷肥可以缓解砷对水稻生长的抑制作用. 上述结果表明，低浓度的磷、砷具有协同效应，高浓度的磷、砷表现拮抗作用. 此外，相同磷、砷水平下，供试耐低磷水稻的生物学性状及其相对值较低磷敏感水稻大；但相对磷吸收量（除磷处理为150 mg/kg外）比低磷敏感水稻小，而砷吸收量及其相对值均比低磷敏感水稻多，这可能与二者的磷营养特性及水稻对磷和砷的竞争吸收有关. 图7 表1 参19
Abstract:
One low-P tolerant rice genotype and one low-P sensitive rice genotype were used to study the effect of P and As couple stress on their growth, and P and As absorption of their seedlings planted in soil. The results showed that at the same P level, the biomass, leaf width, plant height, SPAD value and total P of the rice genotypes increased with As concentration ranging from 0 mg/kg to 25 mg/kg, and then decreased with As concentration increasing to 50 mg/kg. The two rice genotypes showed the same tendency, which means meant that a small quantity of As might stimulate rice growth and absorb more P, while 50 mg/kg As would start to suppress rice growth and P absorption. At the same As level, the biological characters and P and As absorptions of the rice genotypes increased along with increasing of P supply. So proper P supply might alleviate the inhibition of rice by As. These indicated that the low levels of As and P displayed synergistic effect, while high levels of those displayed antagonism effect. Moreover, At the same P and As levels, the biomass, leaf width, plant height and SPAD value of the low-P tolerant rice genotype and their relative values were larger than those of low-P sensitive rice genotype, but the low-P tolerant rice genotype also absorbed more As than the low-P sensitive rice genotype, indicating that the uptake capability of rice to As might be related to its P nutrient character and its competitive absorption between P and As.
