Fig. 1. The germination situations at the end of the seventh day of Allium cepa L. seeds. Group I (control) was treated with distilled water; Group II was treated with 0.15 M NaCl alone; Group III was treated with a 40 mg L 1 dose of KNO 3 ; Group IV was treated with a 40 mg L 1 dose of KNO 3 +0.15 M NaCl.

In this work, the effects of potassium nitrate (KNO3) on the seed germination, seedling growth (radicle length, radicle number and fresh weight), mitotic activity and chromosomal aberrations of Allium cepa L. germinated under both normal conditions and salt stress were studied. The final germination percentages, radicle lengths, radical numbers and fresh weights of onion seeds germinated in the medium with KNO3 alone were statistically the same as ones of the control seeds germinated in distilled water medium. In addition, the mitotic index in root tip meristems of A. cepa seeds germinated in the medium with KNO3 alone demonstrated a decrease according to ones of the control seeds germinated in distilled water medium, while their frequency of chromosomal aberrations showed an increase according to the control. On the other hand, salt stress considerably inhibited the seed germination and seedling growth of A. cepa. Furthermore, it markedly decreased the mitotic index in root tip meristems of the seeds and increased the number of chromosomal aberrations. The detrimental effects of salt on the seed germination, seedling growth, mitotic activity and chromosomal aberrations was dramatically alleviated in varying degrees by KNO3 application.

... Furthermore, there have been no findings published so far demonstrating the genotoxic effects of salinity on this plant's enzymatic parameters. Lathyrus sativus is a fantastic model organism (Cavuşoğlu et al. 2017) for assessing all potential consequences, particularly at the chromosomal level following various levels of stress production caused by high salt (100-500 mM NaCl). ...
