light intensity
However, in habitats lacking sufficient nutrition and with higher light intensity, survival rates and space-occupying ability of two kinds of seedlings (sexual and asexual produced) were low and the space would be preempted by grown-up plantlets.
      
The time required for fluorescence to reach its peak intensity and the degree of fluorescence quenching depending on light intensity are analyzed.
      
In the diatoms limited in nitrogen and assimilating exogenous glucose, P was found to decrease or increase depending on the light intensity, glucose concentration, and the duration of exposure.
      
In the diatoms assimilating both nitrate nitrogen and glucose, compared to those supplied with nitrates alone, P was higher at the medium and high light intensities and lower at the low light intensity.
      
High light intensity improved the physiological state of carp yearlings, while zero illumination had an inverse effect.
      
Full disappearance of Chl a forms at 668, 676, and 690 nm and a sharp decrease in Chl b form at 648 nm in treated seedlings grown under 30 or 100 lx light intensity shows close contact of these forms with carotenoids in the thylakoid membrane.
      
Incorporation of labeled nucleotides increased with increasing light intensity.
      
The particle distribution function over the diameters was found by means of the light intensity emitted by the stream of particles.
      
The effect of channel geometry on the reproducibility of the integrated light intensity was studied.
      
In vivo, this size is controlled by light intensity during growth, thus implying more sophisticated optimization strategies, since larger antenna size demands finer structural tuning.
      
We demonstrated that the BChl c: BChl a ratio in the chlorosomes varied from 55: 1 to 110: 1, depending on light intensity.
      
The development of plants depends on the photoperiod length, light intensity, temperature, and length of light day integral.
      
At low modulation frequencies, the real and imaginary components are of the same sign, whereas at high modulation frequencies the components have opposite signs (photocurrent lags behind a change in the light intensity).
      
It was found that the light intensity affect the lipid content and fatty acid (FA) ratios in the algae.
      
The lipid content was 2.5-3.6 times higher in the algae at low light intensity.
      
After maintenance of the branches in an aquarium under a light intensity of 30% PARs for 30 days (experiment 1) or for 90 days (experiment 2), the samples were exposed to 95% PARs for 120 days in the same aquarium.
      
Off-to-on state switching under a fixed light intensity and a pulse supply voltage is considered.
      
Evaluation of the Effect of Light Intensity on the Measurement of the Photosynthetic Rate in Plankton Microalgae by the Chloroph
      
On the basis of the energy model, we determined the upper limit bmax = 0.003 for light intensity range I>amp;lt; 4.4 W/m2 and the lower limit bmin = 0.0003 for I = 400 W/m2.
      
The degree of light-induced activation of FNR was dependent on the light intensity, the duration of plant exposure, and the leaf age.
