摘　　要：对沙角衣藻 杂交水稻体系在含可溶性有效磷、磷矿石粉和无磷的三种培养基中有效磷浓度和碱性磷酸酶活性变化关系的研究结果发现:在全磷培养基中,随着有效磷含量的减少,体系中碱性磷酸酶活性随之升高;其中含磷矿石粉的无磷培养基中,加藻比无藻的培养基的碱性磷酸酶活性升高更突出;在无任何磷源的体系中,有藻的培养基碱性磷酸酶仍呈上升趋势,表明在缺磷胁迫下,藻和水稻都能产生碱性磷酸酶分解矿石磷.In this paper, the authors discussed the relation between the phosphorus density and the alkaline phosphatase activity in the algae (Chlamydomonas sajao Lewin)-rice (O.sativa L.) experiment system.Three culture mediums were designed: having available phosphorus, having phosphate rocks and without any kind of phosphorus.It was found that alkaline phosphatase activity was increased when Chlamydomonas sajao Lewin was transforming and availing the phosphate rocks.As a result, the concentration of the available phoasphorus in the medium increased greatly.
