Because there were no significant differences in light condition under the canopy in vertical, the saplings came into their first suppression period when they were 5—8 years old, with a height growth rate less than 0.1 m·a-1 lasting for 10 years.
+7g/lGelatin, feasible illumination intensity was 3-5d dark culture combined with 1000-15001x light culture 12h/days, the highest multiplication rate was 9.3. On average, there were 32 shoots white can be used for rooting in one bottle.
The results indicated that the total radiation and PAR were respectively 90% and 71% of full sunlight in gap center, and 30～40% and 25～33% in expanded gaps,while the light under canopy was less than 10% of full sunlight.
Oil Contents of Cinnamomum pauciflorum seedlings under 61.5% and 33.8% full sunlight were higher than that of plants under full sunlight by 5%,but oil content of Cinnamomum pauciflorum seedlings under 15.4% full sunlight was lower than that of plants under full sunlight by 5%.
The heterogeneous features of the distribution of litter, fine roots, and sunlight was estimated by employing the geostatistics, and the standing biomass of litters, fine root biomass, and light transmittance, as well as the production and turnover of fine roots of larch trees were calculated base on the estimation.
In light of Brenti's work on certain R-polynomials, this formula raises interesting questions about the possibility of relating Ext groups between Weyl modules to Kazhdan-Lusztig combinatorics.
Light microscopy revealed compressed villi, oedema, mononuclear cell filtration, and vacuolization on the cytoplasm of epithelial cells in the jejunum of hyperlipidemic rats.
A seaweed-chamber experiment was performed, indicating that gaseous I2 is one of the important precursors that lead to new particle formation in the presence of solar light in the ambient air at the coastal tidal area.
Investigation on the acute biochemical effects of light rare earths on rat serum by NMR-based metabonomic approaches
1H-NMR spectroscopy and pattern recognition (PR) method were used to assess the acute biochemical effects of light rare earths.
But when it was irradiated under UV illumination or solar irradiation for some time, the catalyst could be reused without loss of catalytic activity.
For three tested samples, under UV illumination CCT01 has the highest activity for MB photocatalytic degradation, while in the case of RB, CCT02 is the most active photocatalyst.
Under visible light illumination, CCT005 has the highest activity for both MB and RB photocatalytic degradation.
After treatment of the mycelium with 5-azacytidine, the protoperithecia formation was accompanied by inversely proportional changes in the formation of conidia, both in the dark and after illumination.
A New Type of Adaptation of the Cyanobacterium Spirulina platensis to Illumination Conditions
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.
