[Objective] The research aimed to study the influence of temperature on the growth of Hydrilla verticillata in the wastewater treatment process.[Method] By using the single factor experiment design,four temperatures which were 5,15,25 and 35 ℃ were set.The growth situation of H.verticillata under the different temperatures was observed in the treatment process of domestic sewerage.[Result] H.verticillata grew luxuriantly at 35 and 25 ℃.Via the cultivation of 15 days,the plant length,branch number,root number and biomass of H.verticillata respectively increased 2.8 and 1.2 cm,7.0 and 5.9 branches,6.2 and 3.7 roots,21% and 25%,which were all significantly or extremely significant higher than that at 5 ℃.Under the cultivation condition of 15 ℃,H.verticillata grew slowly.The increment of plant length,branch number and root number were higher than that at 5 ℃,but they had no significant difference.[Conclusion] During 5-35 ℃,the higher temperature could promote the growth of H.verticillata in wastewater treatment process.
