摘要

The authors found out from the results of previous experiments that some morphologicali changes of corn plants by the wilting treatments were due to the raising of auxin level in the neighbouring of nodes, but it has been unknown what is a main cause in its process, namely, whether the raising of tryptophan (TTP) as the precursor of IAA produced of common proteins by hydrolysis or the conversion of bound auxin to free auxin. In order to discuss these problems, the spray treatments on corn plants with tryptophan (TTP) and naphthalene acetic acid (NAA) solutions were tried. 1. Both NAA-spray treatment and TTP-spray treatment on corn plants accelerated the internodal elongation, and the differential influences have beep observed remarkably in the case of the former treatment in comparison with the latter. The former made the interrnodal elongation accelerate considerably on each internode which had finished their elongation or was elongating vigorously. On the internodes which were going to elongate, the latter made those elongation accelerate, but the former made them reduce even with lO ppm solution. 2. The slack influence appeared on the elongation of leafblades under TTP-spray treatment, because each of leaves appeared after the treatment was made to increase in length. NAA-spray treatment have influence on the elongation of all leafblades which were elongating and it accelerated those elongation directly with lOppm solution, but reduced with lOppm solution. 3. The influence of TTP-spray treatment on the growth of born plants was confirnled repeatedly and the results were like the wilting treatment that brought on the increace of the length of internodes and leafblades. 4. It seems that the increase of auxin content in the neighbouring of nodes under the wilting condition is due to the raising of TTP produced of common proteins by hydrolysis.

NAA喷雾处理和玉米植物的TTP喷雾处理均加速了剧本伸长率，并且在与后者相比，在前一种治疗的情况下显着地观察到差异影响。前者使互联网伸长率大大加速，每个节间加速，在每个都是伸长的，或者剧烈伸长。在将要伸长的内部，后者使那些伸长率加速，但是甚至用LO PPM解决方案使它们降低。 2.在TTP喷雾处理下的叶片伸长率上出现了松弛的影响，因为在处理时，每种叶片出现在长度上增加。 Naa-Spray治疗对伸长的所有叶片的伸长率有影响，并且它直接用LopPM溶液加速了那些伸长率，而是用LoPPM溶液减少。 3. TTP喷雾治疗对出生植物生长的影响反复构建，结果是萎缩的处理，从而提高了间叶片长度的增强。 4.似乎在衰竭条件下，节点附近的疾病含量的增加是由于通过水解产生常见蛋白质的TTP。
