North Carolina and Bermuda isolates of the green seaweed Ulvaria oxysperma (Kuetz.) Bliding were grown in cross-gradient light-temperature culture to determine the effects of varied photon fluence
rates, temperature and photoperiod on their growth and reproduction. Results indicated significant genetic-based variation
between the two populations.
Spheroplast were obtained from the vegetative thallus of the North Carolina isolate following enzymatic digestion with abalone
gut extract and maceration. Single cell isolates developed new cell walls in 2–3 days and attached to nylon net substrate.
Cultured isolates regenerated into juvenile plants with normal development and morphology.
Results are discussed in terms of the suitability of this economically important species for land-based mariculture. 相似文献

The pattern of development of a fouling community, based on research data on their formation in the mussel culture in the White Sea is presented. The succession may come to an end either by the mussel community or by the community of Styela rustica, which is analogous to the natural epitbenthic biocenosis of Laminaria saccharina. It also might develop with the deletion of some stages. The presence of the mussel phase is not necessary in the development of fouling. The final stage of the fouling development is determined, apparently, by hydrological conditions. 相似文献
