Influence of IAA on the cellulose density of in vitro pollen tubes in Torenia fournieri
| Culture time (h) | Treatment | No. of pollen tubes | The average fluorescence value | The total areas of pixels falling within pollen tubes | The total cellulose fluorescence value of pixels falling within pollen tubes |
| 0.5 | Control | 26 | 138±5 | 573±45 | 79030±3545 |
| IAA | 45 | 106±4*** | 742±90** | 75569±5186* | |
| 1 | Control | 44 | 94±9 | 1039±313 | 114882±258 |

Values given in the table are means and standard errors of three experiments. The analysis of significant variance was performed between the control group and IAA treatment according to Student's unpaired ttest. Comparison was made on the same treatment time.
* P > 0.05 indicates no difference; ** 0.01 < P < 0.05 indicates distinct difference; *** P < 0.01 indicates extreme distinct difference.
