Figure 1.
Differences in electrical conductivity (EC) in root samples of rice plants treated with different levels of Gd-DTPA for different periods of time.
Figure 2.
Comparison of plant heights after short-term treatment with different concentrations of Gd-DTPA solution.
Figure 3.
MRI images (transverse slices) of rice root samples immersed in different concentrations of Gd-DTPA for 3 h (A), 6 h (B), 9 h (C) and 12 h (D).
In each image, numbers 1 to 5 represent 0-DTPA, respectively.
Figure 4.
Average signal intensity (ASI) values of root samples that treated with different concentrations of Gd-DTPA at all four different time points.
Figure 5.
Spin-lattice relaxation times (T1) of root samples that treated with different concentrations of Gd-DTPA at different time points.
Figure 6.
Concentrations of Gd in rice roots treated with 5-DTPA at different time points.
Figure 7.
MRI image of rice root immersed in 5-DTPA for 6 h (A).
Aging or dead tissues is marked with arrows. Image B shows a photograph image of the root sample.
Figure 8.
Treatment with 5-DTPA in different growth media.
The plant height was altered at different growth periods. The growth media included sandy soil and paddy soil. A1 and B1 represent sandy soil and paddy soil treated with Gd-DTPA, and A2 and B2 represent untreated sandy soil and paddy soil, respectively.
