Abstract  

The effects of IAA on the growth,chlorophyll and protein content of Ulva pertusa were studied under room temperature of 22℃ and continual lighting of 40 μE·s-1·m-2.Results showed that the concentration of IAA ranged from 0.01 to 10.00 mg·L-1 had different level effects,compared with the control group.With the increasing of IAA concentration,the diameter and the chlorophyll and protein content of Ulva pertusa in experiment group also increased.It was also suggested that the optimal growth and the max value of chlorophyll and protein content of Ulva pertusa achieved when the concentration of IAA was 1.00 mg·L-1.However,the growth of Ulva pertusa was found fractional inhibited and the content of chlorophyll and protein had began to degrade,when the concentration of IAA exceeded 3.00 mg·L-1.

Key wordsUlva pertusa      IAA      growth      chlorophyll      protein
