本文概述了生长素生长调节的主要特征，并将其与fusicoccin的生理特性并列。质膜定位的H+/K+ ATP酶在生长反应中的基本作用进行了检查，并简要回顾了有关这种酶的信息。创伤对这种酶的活性的影响进行了详细说明，并得出结论，切除的组织段的生长停止不缺乏激素，但从ATP酶功能的损害。另外一个对激素研究具有重要意义的结论也得到了证实，即在切除的组织中，生长素通过实验实现了生长的再激活，这在很大程度上代表了损伤的加速恢复。此外，钙调素/Ca 2+系统可能是这个恢复步骤中的重要中间体。最后，无知的主要领域，倾向于增长，被认为是。
SummaryThis article outlines the main features of growth regulation by auxin and places them side‐by‐side with the physiological properties of fusicoccin. The fundamental role of the plasma membrane located H+/K+ATPase in growth responses is examined and the information about this enzyme briefly reviewed. The effects of wounding on the activity of this enzyme are detailed and it is concluded that growth in excised tissue segments ceases not from lack of hormone but from impairment of ATPase function. An additional conclusion of major importance for hormone studies is reached; that is, that the experimentally‐realized reactivation of growth by auxin in excised tissues represents largely an accelerated recovery from injury. Furthermore the calmodulin/Ca2+system may be an essential intermediary in this recovery step. Finally, the major area of ignorance, predisposition to growth, is considered.
