Abstract
The study aimed to investigate the characteristics of the diploid and tetraploid Indigofera tinctoria L. which were induced by colchicine. Their growth rates and morphological traits were compared before the production from their planting plots would be evaluated in the future. Regarding the growth rates of both the diploids and tetraploids investigated from many features, it was found that the teraploids, on statistical basis, significantly had higher growth rates in terms of having more leaflets and branches than those of the diploids. However, in terms of their height, circumferences, and number of nodes, both the tetraploids and diploids did not have significant different growth rates at statistical level. Nevertheless, there was a tendency that the growth rates of the tetraploids were higher than those of the diploids in every aspect. When comparing the seventeen-weeks old Indigofera tinctoria L. diploids with the tetraploid Indigofera tinctoria L., it was found that their heights, circumferences, node numbers, branch numbers, leaflet numbers per one compound leaf were not statistically different from each other. The numbers of their compound leaves significantly differed from each other at the statistical level, though. That is the diploids had more compound leaves than those of the tetraploids. In the meantime, the tetraploids’ leaflets were wider and their leaflet index was significantly higher than those of the diploids at statistical level although their leaf lengths were not statistically different. In addition, the tetraploids tended to have more compound leaf weight, leaflet weight, leaflet area, and leaflet weight/leaflet area than those of the diploids.
