Abstract:
Effects of light emitting diode(LED)with different intensities and qualities on growth and morphology of ‘Yugan’ pepper seedlings were studied,which aimed to provide the data base for industrialized cultivation.Through the two-factor experimental of three light intensity(50 μmol?m-2?s-1，100 μmol?m-2?s-1，150 μmol?m-2?s-1)and two light quality(red and blue).The results showed that there was the significant effect of light intensity and light quality on the growth of ‘Yugan’ pepper seedlings,and the interaction between light intensity and quality.The sole effect of light intensity on seedlings were further analyzed,which showed that the height,stem diameter,leaf number,branch number and stem spacing of seedlings were higher under 100 μmol?m-2?s-1 than 50 μmol?m-2?s-1 and 150 μmol?m-2?s-1.The experiment of light quality showed that the plant height,branching point high,spacing of stem,leaf length,leaf width and fresh weight were significantly increased by red LED,the branch number was significantly increased by blue LED,the biomass of seedlings by red∶blue=8∶1 was between red and blue LED.
