Summary:Physical and chemical mutations can cause such genetic changes naturally at low rates or spontaneously. Polyploidy has played a significant role in higher plant evolution and diversification. Chromosome doubling chemicals including colchicine, trifluralin, and oryzalin have been used to promote artificial polyploidization. Ploidy manipulation can cause morphological and physiological changes in plants by changing nuclear DNA content, gene expression, and developmental processes. Polyploid plants have more biomass, higher yield, better biotic and abiotic stress tolerance, and higher primary and secondary metabolites. Plant's ploidy can be determined in two ways : Directly and indirectly.
