| Source | D.F. | MGT | GI |
| T | 7 | < 0.001*** | < 0.001*** |
Note: All values are showed as mean (S.E.) (n = 8). Within a column for MGT and GI of each temperature, values followed by different letters are significantly different by least significant differences of Duncan’s new multiple range test.
*** means P < 0.001.
a, seed were no germination at 10°C; thus, MGT and GI could not be calculated.
