| Abstract | ||
| An experiment was conducted in plant laboratory, Plant Protection Dept., College of Agriculture, University of Kufa. Hornwort samples were collected from Kufa River during August, 2006. The aim of study was determined the effect of different levels of pH on growth parameters (plant fresh and dry weights, number of branch and length) of plant and knowledge optimum and maximum pH plant can growth in it. Plants were placed into aquarium containing solutions, with pH values (7.00, 9.58, 10.19, 10.94, 11.43, and 12.23) with three replicates. Results showed that the control treatment (pH = 7.00) due to producing the highest values of measured growth parameters. Meanwhile, treatment of (pH = 12.23) gave the lowest values for the above mentioned parameters. | ||
