Various stages of the life cycle of the marine brown alga Laminaria saccharina (L.) Lamour. (Laminariales, Phaeophyta) including male and female gametophytes, female gametes, zygotes and young sporophytes of different age were investigated for their potentials of carbon dioxide ((14)CO2) fixation. Rates of photosynthesis attain the same order of magnitude in all stages. Photosynthetic (14)CO2-fixation is accompanied by a substantial light independent carbon assimilation. This is confirmed by rate determinations of the equivalent carboxylating enzymes present in the plants, ribulose-1,5-bisphosphate carboxylase (EC 4.1.1.39) and phosphoenolpyruvate carboxokinase (EC 4.1.1.32) as well as by chromatographic analyses of the appropriate [(14)C]-assimilate patterns.
研究了海洋褐藻海带（Laminaria saccharina）（Laminariales，Phaeophyta）的各个生命周期阶段，包括雄性和雌性配子体、雌性配子、受精卵和不同年龄的幼孢子体，以研究它们固定二氧化碳（(14)CO2）的潜力。所有阶段的光合作用率都达到了相同的数量级。光合作用（14）CO2 固定伴随着大量的光独立碳同化。这一点通过对存在于植物中的等效羧化酶（核酮糖 1,5-二磷酸羧化酶（EC 4.1.1.39）和磷酸烯醇丙酮酸羧激酶（EC 4.1.1.32）的速率测定以及对适当的 [(14)C]-同化模式的色谱分析得到了证实。
