Chromosome doubling in plants
WebMay 4, 2024 · The obtained chromosome doubling plants grew slower than the conventional plants in the subculture in the early stage, but the growth rate after subculture 2–3 times was no significant difference between chromosome doubling seedlings and the conventional seedlings. The reason for this remains to be further analyzed. WebImprovements are constantly being made but the most widely used and most successful method for chromosome doubling of haploid plants is the use of a mixture of 0.2–0.4% colchicine and 1–2% dimethyl sulfoxide depending on the genotype and species.
