| Abstract: | In order to compare the differences of different clones of diploid and tetraploid Robinia pseudoacacia tissue culture plantlets, the morphological and physiological indexes of the diploid and artificially induced tetraploid tissue culture plantlets of Robinia pseudoacacia were determined and analyzed. The results showed that the growth and stress resistance of most tetraploid Robinia pseudoacacia clones were better than that of diploid clones; there were abundant variations between and with diploid and tetraploid Robinia pseudoacacia clones in different morphological and physiological indices, but the variation of tetraploid Robinia pseudoacacia was more abundant; there were complex correlations among the tested indices. Comprehensive consideration should be taken in selection and breeding. According to the results of the experiment and the breeding objectives, the excellent tetraploid Robinia pseudoacacia clones can be selected to enrich the germplasm resources of Robinia pseudoacacia and increase its genetic diversity. |
