Polyploidization, or genome doubling, has a significant impact on plant speciation and adaptation, and it is commonly used in agriculture to improve crop traits. In this study, we investigated the induction of polyploidy in three wild Allium species native to Korea: A. senescens and A. spirale Willd. and A. taquetii, using colchicine treatments tailored to meet specific experimental requirements. By avoiding tissue culture methods, we developed a more accessible, cost-effective, and scalable approach to polyploidization. Our research demonstrated that polyploid Allium plants exhibit distinct phenotypic changes, such as reduced growth rates and increased stomatal size. Flow cytometry and chromosome counting confirmed the successful induction of polyploidy, with clear peaks indicating double DNA content and stable chromosome numbers in polyploid plants. The presence of B chromosomes in A. spirale Willd. following polyploidization suggest interesting genetic dynamics.
Despite the initial growth lags, polyploid plants may offer enhanced photosynthetic efficiency and resilience under optimal conditions. This study highlights the potential of polyploidization to improve ornamental traits in Allium species, thereby contributing to the diversification and sustainability of ornamental plant offerings.
Future research should focus on the long-term performance and ecological adaptability of polyploid Allium species to fully harness their horticultural potential.
