32P isotope tracing technique was used in this study,and the results indicated that phosphorus stored or pre-existed in roots would be remobilized in maize under phosphorus deficiency from root cortical cells with lysis to shoot mostly rather than root apex during aerenchyma formation.

Kraus等的试验表明玉米根系从土壤中吸收的32P可在根皮层内保留15 d，之后逐渐减少[2]。这意味着与叶片的情形相似，根内也进行着磷的活化和再运转。当植物处于磷胁迫下时，根系吸收的磷素远不能满足植物各器官生长发

但是实验主义似乎如此广泛地与任何种类的评论意识密切合作，以至于稀释先锋派公式成了沉思者的烦恼——特别是如果你真是的话，正如法兰生回忆他自己，"那些瘦瘦的年轻人中的一个，戴着吓人的眼镜"，"看上去他们掌握了大量关于贴上小标签的滚石乐团的资料。"

巴西橡胶树是重要的经济树种，其独特的乳管结构和生产期长的特性，有可能发展成为一个高效、低成本的"植物生物反应器"，潜藏着巨大的商业开发价值。

Through one week field work and laboratory classification and identification, the species of the periphyton community in the water are examined.

岩溶泉水体的这种着生藻类群落结构的形成与岩溶泉水的富钙、偏碱性有很大的关系。
