| 摘 要： | 缺硫培养6天的水稻幼苗,其叶片和根中的硝酸还原酶(NR)活性明显下降。用1pPm 的6-苄氨基腺嘌呤(6-BA)处理培养了10天的水稻幼苗根系,24小时后缺硫培养的水稻幼苗叶片和根系的 NR 活性升高,加硫培养的水稻幼苗叶片和根中的 NR 活性下降。用~(35)S示踪发现,6-BA 可降低加硫幼苗对~(35)S 的吸收和转化,但促进缺硫幼苗对~(35)S 的转化。

| Abstract: | The effects of sulfur and 6-Benzyladeine on the nitrate reduetase activi- ty in rice seedlings were studied by the water culture method.The activity of nitrate reductase was decreased,when plants were grown in sulfur deficient solution.Both sul- fur deficient plant and the control were treated in nutrient solution with 6-Benzylade- nine concentration of 0.01,0.1 or 1 ppm.It was found that the nitrate reductase acti- vity of former plant was increased.while the activity of the latter one was decreased. When the plants were treated in untrient solution with 6-Benzyladenine concentration of 1 ppm,the transformation of inorganic sulfur to organic compounds was markedly incre- ased in the sulfur deficient plant.However it was decreased in control plant. |
