Abstract


In order to see any effect of GAA_3 on the rates of respiration and photosynthesis in Chorella, the plants were cultivated in media under 10,000Lux of light at 25。c. of temperature, supplied the air containing 25% of carbon dioxide (CO_2) and the media were set up in six kinds of concentration of GAA_3 such that one was for the control (no GAA_3) and other five, for the experimentals (10, 50, 100, 150 and 200 ppm of GAA_3)
The results of the examination after six days of cultivation showed that the growth of Chlorella cell was enhanced in all of five experimentals, especially the most conspicuous acceleration was shown in 10 ppm of GAA_3 and the acceleration rates in comparison with the control are as follows: packed cell volume, 240%; cell number, 410%; chlorophyll contents, 280%.
The results of the present experiment also showed that the respiration rate was enhanced but photosynthesis was restrained in less than 100 ppm of GAA_3 and the situation was reverse in more than 100 ppm of GAA_3.
