Abstract

The effects of photosynthetic photon flux（PPF） and electrical conductivity（EC） in a nutrient solution on growth of Chrysanthemum morifolium plantlets using a microponic system were studied. Results showed that with high PPF （250 molm-2s-1），the pH and EC value of the nutrient solution changed significantly. Compared to the other two treatments（0.8 and 1.6 mScm-1 of EC，50 and 100 molm-2s-1 of PPF），a high PPF（250 molm-2s-1） and EC （3.0 mScm-1） increased fresh weight，dry weight，shoot length，root length，and number of new leaves. Also，compared to the two lower PPF treatments（50 and 100 molm-2s-1），with the high PPF，CO2-uptake，stomatal conductance，and transpiration in leaves were higher. Thus，a high PPF and EC value for the nutrient solution was favorable for the growth of Chrysanthemum morifolium plantlets in a microponic system culture.［Ch，5 fig. 1 tab. 11 ref.］
