Abstract

It was shown that the early growth of Trapella sinensis seedlings can be divided into two distinct stages based upon susceptibility for different growth‐regulators, such as gibberellin, kinetin, and the extract of Chlorella cells grown in light. The two stages were observed on the 7th and the 10th days, respectively. Especially the epicotyl showed different sensitivities to the growth regulators mentioned above. The effect of gibberellin (GA~3~), kinetin and the extract of Chlorella cells grown in light on the growth of T. sinensis seedlings after germination at 23 °C in light at 2000 lux was investigated. Each addition was done at zero time and after 3, 6 and 10 days growth, and the effect was observed subsequent every 3 or 4 days.
