摘要: The diatoms Ditylum brightwellii and Nitzschia turgidula were grown in semi-continuous culture under various combinations of light intensity, temperature daylength (photoperiod). Growth was strongly limited by intensities below 0.03 cal/em2. min both species. Above this saturation growth rapidly approached but only gradually so Ditylum. rate continuous never significantly higher than with 16 hours plus 8 dark. In Ditylum, above cal/cm2. caused a strong inhibition at all temperatures. chlorophyll concentration the cells greater shorter photopceriod. cultures synchronised different intensity photoperiod, cell division generally took place light. Synchrony best short photoperiods bright Time courses are shown for synthesis photosynthesis cultures.
