Following these preliminary treatments, the plant's root tips were preserved using a combination of glacial sulfuric acid and absolute ethanol in a 1:3 proportion. After fixation, the root tips were stained with a 0.5% solution of basic fuchsine in preparation for chromosome analysis, involving the creation of squash preparations. These dyed root tips were gently pressed in a 1% acetocarmine solution with zinc chloride as a mordant. Subsequently, the produced slides were scrutinized under a microscope. The results revealed that most in vitro-cultivated plantlets exhibited chromosomal stability, while a minority of the seedlings displayed aneuploidy.}, DOI = {} }
