Preparation of the Test Substrates
Stock solution (10000 mg/L): directly dissolving 1.0036 g test substance into 100 mL acetone.
The test medium was prepared by adding appropriate test solution and to 100 g quartz sand. Then 30 mL deionized water was thoroughly mixed.
The test substrates for concentration analysis were prepared at the same time, while no deionized water added. Details of the media preparation are showed as follows:

Test Performance
Fresh test solutions were added to glass dishes that were filled with 100g clean quartz sand. The seed was then positioned on the substrate allowing adequate room for anticipated growth. The radicle end of the seed was aligned in the direction of this growth. The dishes were sealed with preservative film with some holes. The dishes were then placed in a climatic chamber. During the test, the following conditions were maintained:
Light: complete darkness.
Temperature: (25±1) °C.
Humidity: (80±5) %.
Seeding densities: 15 seeds /dish for range-finding test.
Replicates: none for range-finding test.
The test period was ended when at least 65 percent of the control seed had germinated and developed roots at least 20 mm long. When both conditions were satisfied, the mean number of seed germinating and mean root length per treatment (and control) were determined. EC50s for germination and root elongation were determined for each species tested and reported along with their 95 percent confidence limits. - Details on test organisms:

EC50s for germination and root elongation were determined for each species tested and reported along with their 95 percent confidence limits.
Observations & Measurements
As different seed germination and root elongation varies dependent on species, the exposure duration for each test species were shown in followed table. When the exposure ended, numbers of seeds that germinated were counted and root lengths measured. All root elongation measurements for a given species were made sequentially before proceeding to the next species. Root length was measured from the transition point between the hypocotyl and root to the tip of the root.
Temperature in the germination facility was reported at the start and the end of the test. The pH of the test solutions was recorded at the initiation of the test.
Validity of Test
(1) Control group
One blank control and one solvent control series were also run in addition to the treatment series.
(2) Validity of test result
During the whole test period, more than 65 percent of the blank control and solvent control seed germinated at the end of test. Therefore the test was considered valid.
Data Processing
For the estimation of the Lowest Observed Effect Concentration (LOEC), and hence the No Observed Effect Concentration (NOEC), for effects of the chemical on root elongation, the mean growth rate for each concentration were compared with the control mean using a multiple comparison method of Dunnett’s tests (ANOVA, SPSS 17.0).
For the estimation of the Lowest Observed Effect Concentration (LOEC), and hence the No Observed Effect Concentration (NOEC), for effects of the chemical on germination, Chi-square Test was used (SPSS 17.0).
Probit analysis (SPSS 17.0) was used to calculate the EC50 and EC50 confidence limits. This method was not carried out because of the low toxicity of the test substance. - Nominal and measured concentrations:

- Analysis Results of the Test Concentration
(1) Specificity
Under the above UPLC condition, the retention times of test substance was about 2 min, 3.9 min and 9.3 min (see Figure 2), while there was no chromatographic peak at the retention time for the control sample (see Figure 3). The results showed that the chromatographic peak was the characteristic peak of the test substance. And the analytical method had specificity.
(2) Calibration curve
A series of standard solutions with concentrations of 0, 0.50, 1.00, 2.00, 5.00, 10.0 and 20.0 mg/L were measured under the UPLC conditions mentioned above. Based on the test result, a linear regression equation was obtained between the concentration and the sum of 3 peak area: A=102565c-5988.5, with good linearity of r2 = 0.9999, where A represents peak area (AU); and c is the concentration of the test substance (mg/L) (see Figure 1). The results showed that linearity for concentration range of 0 to 20.0 mg/L was good.
(3) Detection limit and quantitation limit
The detection limit was 0.06 mg/L (S/N ≥ 3), and the quantitation limit was 0.20 mg/L (S/N ≥ 10).
(4) Analysed results of the test concentration
According to the test result, the analysed concentration for nominal concentration of 100 mg/L, 500 mg/L and 1000 mg/L were 99.1 mg/L, 497 mg/L and 1015 mg/L respectively (Table 1). The measured concentrations were more than 90 percent of the nominal concentrations, so the final test results were based on nominal concentrations.
Effects on Germination Rates and Root elongations
Table 3 showed germination rates and germination inhibition rates observed for the seeds of different species. Table 4 to Table 13 showed root lengths and root lengths inhibition rates observed for the seeds of different species
At the end of the test, over 65% of the control seeds germinated and the roots developed were longer than 20 mm. Compared with the germination rates of the blank control and solvent control groups, the germination rates of the highest concentration group (1000 mg/L) were < 50%.
The mean root length for each concentration was compared with the solvent control mean using an multiple comparison method of Dunnett’s tests (ANOVA PSS 17.0). The results showed that no significant difference was observed for Brassica chinensis L. (Cabbage), Lactuca sativa (lettuce), Oryza sativa L. (Rice), Brassica oleracea (Kohlrabi), Cucumis sativus (cucumber), Zea mays (corn), Sesamum indicum (sesame), Lycopersicon esculentum (tomato), Glycine max (Soybean) and Raphanus sativus (Radish) (p > 0.05).
According to the statistical results of the germination rate for each seed by analysis of Chi-square Test (SPSS 17.0), the germination rates of all treatments for the 10 seeds shown no significant different (p > 0.05).
Under valid test conditions, the LOEC, NOEC and EC50 for Brassica chinensis L. (Cabbage), Lactuca sativa (Lettuce), Oryza sativa L.

Under valid conditions, the phytotoxicity of the test substance (GL500) to 10 terrestrial plant species was conducted according to “The guidelines for the testing of chemicals” (HJ/T 153-2004).
In the test, 10 plant species including Brassica chinensisL. (Cabbage), Lactuca sativa (Lettuce), Oryza sativaL.(Rice), Brassica oleracea (Kohlrabi), Cucumis sativus (Cucumber) , Zea mays (Corn),Sesamum indicum (Sesame), Lycopersicon esculentum (Tomato), Glycine max (Soybean), Raphanus sativus (Radish) (15 seeds/group/species) were exposed to 100, 500 and 1000 mg/Lof the test substance. A blank control and a solvent control without the test substance were run at the same time. At the beginning of the test, the pH values of the test solution were between 6.35and7.56. During the test, the temperature in the germination facility was maintained in the range of 24.5°C to 25.2°C. At the end of the test, more than 65 percent of the control seeds germinated and the roots developed were longer than. So the study met the acceptability criteria prescribed by the protocol. Therefore the test was considered valid.
The initial concentration of GL500 in the test solution at the start of the test was determined by UPLC. According to the test result, the measured concentration of 100mg/L, 500mg/L and 1000 mg/L were 99.1 mg/L, 497 mg/L and 1015 mg/L respectively.The measured concentrations were more than 90 percent of the nominal concentrations, so the final test results were based on nominal concentrations.
The results showed that there was no significant phytotoxicity observed at rates of100mg/L, 500 mg/L and 1000 mg/L in the range-finding test for Brassica chinensisL.(Cabbage), Lactuca sativa (Lettuce),Oryza sativaL. (Rice), Brassica oleracea (Kohlrabi), Cucumis sativus (Cucumber), Zea mays (Corn), Sesamum indicum (Sesame), Lycopersicon esculentum (Tomato), Glycine max (Soybean),Raphanus sativus (Radish) (p> 0.05).
