Abstract：The effects of short -term CO2 enrichment on physiological and biochemical indexes,photo-synthesis and growth and development of Anthurium andraeanum ‘Anthaqxm’were studied in greenhouse. The results showed that CO2 enrichment treatment increased the contents of chlorophyll,soluble sugar,starch and net photosynthetic rate,decreased the soluble protein content,transpiration rate and stomatal conduct-ance,and the value of chlorophyll a /b had no obvious change.CO2 enrichment could also promote the plant growth,development and early flowering,and improve the flowering rate.At the 30th day after treated,com-pared with control,the chlorophyll content of T1 [(500 ±30)μmol /mol],T2 [(700 ±50)μmol /mol],T3 [(900 ±100 μmol /mol)]increased by 12.78%,16.74% and 25.99%,the net photosynthetic rate in-creased by 18.73%,40.25% and 45.06%,the stem height increased by 5.54%,16.22% and 23.36%, and the flowering rate increased by 9.09%,30.30% and 48.48%,respectively.
