以智利江蓠(Gracilaria chilensis)为实验材料,分别研究了智利江蓠在不同光照强度(20μmol·m-2·s-1,72μmol·m-2·s-1,108μmol·m-2·s-1,180μmol·m-2·s-1)和不同温度(12、15、18、21、24和27℃)条件下的生长及生化组分的变化。实验结果表明,最适合智利江蓠生长的光照强度为72μmol·m-2·s-1,温度为21℃。在适宜光照强度和温度条件下,智利江蓠不仅具有较高的生长速率(RGR),而且藻胆蛋白和可溶性蛋白(SP)含量也相应的达到最高值,而丙二醛(MDA)的含量却降到最低值,说明智利江蓠受到外界的胁迫较低。可溶性糖(SS)的含量随着光强的升高而增加,在21℃条件下出现最低值。总体来说,智利江蓠适合在低光照强度和适中温度条件下生长。
In this study, Gracilaria chilensis was used as experimental material to study the effects of different light intensities (20μmol · m-2 · s-1,72μmol · m-2 · s-1,108μmol · m-2 · s- 1,180μmol · m-2 · s-1) at different temperature (12,15,18,21,24 and 27 ℃). The experimental results showed that the optimum illumination intensity was 72μmol · m-2 · s-1 for the growth of R. chinensis and the temperature was 21 ℃. Under suitable light intensity and temperature, the M. chinensis had not only higher RGR, but also phycobiliproteins and soluble protein (SP) content reached the highest corresponding value, while the content of malondialdehyde (MDA) But it dropped to the lowest level, indicating that Chile’s riverside is under the threat of the outside world. The content of soluble sugar (SS) increased with the increase of light intensity, and the lowest value appeared at 21 ℃. In general, Chilean Gracilaria is suitable for growth at low light and moderate temperatures.
