The experimental results showed that the inductivity of chimera buds reached the maximum,or 90.2% when the germ-free plantlets were on the medium of MS+0.2 mg/L 6-BA and under light treatment of 2 000 lx.
Using stems as materials,propagation in vitro of Dioscorea fordii Prain et Burkill was studied under the temperature of(25±1)℃,illumination intensity of 24～30 μmol·m-2·s-1 and illumination time of 10 h/d,in the MS basic culture medium.
以淮山(Dioscorea fordii Prain et Burkill)茎段为材料,以MS为基本培养基,在(25±1)℃、光照强度24~30μmol/m2.s-1、光照时间10 h/d条件下对淮山的组织培养与快速繁殖技术进行了研究.
MS was more effective than other materials as basic medium in the whole experiment. The best medium of proliferation was MS+6-BA 0.2 mg/L+IBA 0.05 mg/L,illumination intensity 1 000 lx,subcultures interval was 4 weeks.
【Method】Qingfeng and Maixiang were growing under the solar greenhouse,the low light was simulated with shade film to the three degree of 100% light intensity(CK),60%-70% light intensity(T1) and 30%-40% light intensity(T2).
The results showed that the growth and physiology indexes of the plug-seedling were obviously better than those of seedlings in other treatments when relative water content of growing media was 70 %-80 %,the amount of fertilizer applied was 500 mL nutrient solution every two days and the light intensity was 320 μmol·m-2·s-1.
Taking root segment of phloxpanicula-ta as explants, affecting central factors, exogenous hormones and light, for the plantlet regeneration were tested. The experimental results showed that root Segment were cultured at a photoperiod of 14 hours daily with medium MS+6-BA1.5mg/L+NAA0.5mg/L for Plantlet Regeneration .
The results showed that, conserved at 0±2℃ and 4±2℃, in darkness for 6 months, the plantlets all survived and could continue to be conserved; conserved at 15±2℃ with a 8h/d photoperiod and 1080 Lux for 6 months, the plantlets were slim .
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.
