Title

Impact of Pretreatment Methods on Chromosome Stability in Regenerated Plantlets

Author

Abstract

The root tips of various in vitro-cultivated young plants, encompassing Anogeissus species, Capparis decidua, and Maytenus emarginata, underwent treatment with colchicine and exposure to cold temperatures at -4°C overnight. 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.

Conclusion

The impact of several pretreatment procedures on the stability of chromosomes in regenerated plantlets of Anogeissus acuminata, Capparis decidua, and Maytenus emarginata was investigated in this work. The findings demonstrated that most plantlets produced in vitro had stable chromosomal counts, notably in the case of Anogeissus acuminata, which exhibited excellent stability throughout several passes. Additionally, Capparis decidua demonstrated a constant chromosome count, contradicting earlier volatility results, with very few aneuploid cells. The appropriate diploid genome count of Maytenus emarginata was verified despite obstacles in the cytological investigation of the regenerants. This work demonstrates how crucial cytological studies are to secure the stability and genetic integrity of regenerants in tissue culture.
