The effect of different photon flux densities (PFD) and temperatures on the relative growth rate (RGR) and the concentration of three halogenated monoterpenes in samples of Plocamium cartilagineum L.( Dixon), a marine alga (Rhodophyceae), were studied. The highest RGR (22.8 +/- 0.04 d(-1)) was obtained at 15 degreebC and 41 ,mol m(-2) s)(-1) of PFD and the lowest (18.0 +/- 0.12 d(-1)) was obtained at 18 degrees C and 120 micromol m(-2) s(-1). The different temperatures and light used in assays did not affect significantly the production of organic compounds. The production of mertensene and violacene was not affected significantly. However, compound 1 reached the highest concentration at 15 degrees C and 65 micromol m(-2) s(-1)). The relationship between growth and production of monoterpenes of P. cartilagineum and the effect of temperature and the PFD were analyzed.
研究了不同光子通量密度（PFD）和温度对软骨藻（Plocamium cartilagineum L.（Dixon），一种红藻门的海洋藻类）样品的相对生长速率（RGR）以及三种卤代单萜浓度的影响。在15℃和41 μmol m⁻² s⁻¹的PFD条件下获得了最高的RGR（22.8±0.04 d⁻¹），而在18℃和120 μmol m⁻² s⁻¹条件下获得了最低的RGR（18.0±0.12 d⁻¹）。测定中使用的不同温度和光照对有机化合物的产生没有显著影响。松节藻烯和紫罗烯的产生没有受到显著影响。然而，化合物1在15℃和65 μmol m⁻² s⁻¹时达到最高浓度。分析了软骨藻单萜的生长与产生之间的关系以及温度和PFD的影响。
