| 摘 要： | 用＾３２Ｐ示踪原子法通过水培试验研究了酸性条件下铝对１年生杉木的根和叶磷吸收和代谢的影响。结果表明，在ｐＨ＝３时，用酸铝处理根和叶后，根中＾３２Ｐ－无机磷增加到对照的１９５％，叶片＾３２Ｐ－无机磷转运指数由４３．０降低到２０．０。根的Ｐ总含量中的各＾３２Ｐ－化俣物比例发生较大变化，无机磷增加到对照的１７５％，有机化合物，脂类化合物，ＤＮＡ，ＲＮＡ分别减少到对照的５５％，４２％，３６％，４０％；叶中

| Abstract: | The influence of acid\|aluminum on the absorption and metabolism of the one\|year\|old chinese fir root and leaf was studied using isotope atom indicator 32 P with water culture. The results showed that after the treatment of the acid\|aluminum(pH=3), the absorption of 32 P\|inorganic phosphorus in root increased to 195% of the CK, the transport index of the 32 P\|phosphorus in the leaf decreased from 43.0 to 20.7. The proportion of the 32 P\|compounds in the root changed, 32 P\|inorganic compounds increased to 175% of the CK, and 32 P\|organic compounds, Lipid, DNA and RNA decreased to 55%,42%,36% and 40%, respectivily. The change of the proportion of the 32 P\|compounds in the leaf was not evident, except the DNA. |
