| Abstract: | With Lico - 6400 portable photosynthesis analysis system, light compensation point and saturation light intensity for the pteridophyte Neottopteris nidus grown in greenhouse were studied. The studies were conducted to investigate the relations between photosynthetic rate and light intensity and temperature. The resuhs showed that the compensation irradianee was 3.8 umol · m^- 2 · s^-1. Saturation light intensity was about 400 umol· m^-2 · s^-1. The net photosynthetic rate was the highest at leaf temperature 30 ℃, the optimal temperature was from 17 to 32 ℃. |
