| Research Abstract |
In this study, I proposed the following hypothesis ; a plant individual can discriminate itself from non-self by chemicals secreted from roots. Based on the hypothesis, I predicted that a mode of competition will be different between interclonal and intraclonal competition and that the difference can be detected by a growth experiment with clonal individuals and chimera individuals.
The growth experiment was conducted with aubergine plants(Solanum melongena L.). I established a method to create a chimera individual composed from two genetically different individuals. However, surviving rates of the chimera individuals were much lower than those of intact plants because of virus infection or unknown reasons. Therefore, it was very difficult to collect enough numbers of replicates. In addition, large variances of growth rates of chimera required larger numbers of replicates than originally planned ones. These unexpected problems made difficult to complete the experiment.
Fortunately, I ran several other experiments relevant to the abovementioned experiment. Their results were currently submitted to the international journals and they are under review now.
