s?1, the blades matured and liberated zygotospores within 6 weeks. Get your free examples of research papers and essays on Physiological Density here.Under the optimum culture conditions of 25 ppt and 14L: 10D at 25☌ and 80 μmol The blades culture at 30☌ produced only archeospores after 2 weeks throughout the culture period. Fast growth of the conchospore germlings was observed at 25☌ under the both of photoperiods in 35 ppt and 80 μmol Early conchospore release occurred at 20-35 ppt and 10L: 14D under 30☌ and 80 μmol A higher physiological density suggests that the available agricultural land is being used by more and may reach its output limit sooner than a country that has a lower physiological density. s?1 of both photoperiods after 2 weeks in culture. The physiological density or real population density is the number of people per unit area of arable land.An early formation of conchosporangial branch was observed at 30☌, 20-40 ppt under 80 μmol s?1 under 35 ppt and 14L: 10D without formation of conchosporangial branch during 6 weeks of culture period.Maximum growth rate of the conchocelis showed at 25☌, 80 μmol s?1), salinity (10-40 ppt) and photoperiod (14L: 10D and 10L: 14D) on the growth and maturation for the conchocelis and blade phase of Porphyra vietnamensis Tanaka et Pham-Hoang Ho from Thailand were examined under laboratory conditions to investigate data of tropical species.The effects of temperature (10-30☌), photon flux density (10-80 μmol Laboratory of Applied Phycology, Tokyo University of Fisheries, 5-7 Konan 4, Minato-Ku, Tokyo 108-8477, Japan Rapeeporn Ruangchuay and Masahiro Notoya * Physiological Responses of Blade and Conchocelis of Porphyra vietnamensis Tanaka et Pham-Hoang Ho (Bangiales, Rhodophyta) from Thailand in Culture
