Role of Propolis in Alleviation of Detrimental Effects of Salt Stress on Some Physiological and Cytogenetical Parameters in Onion (Allium cepa L.)
Dilek Çavuşoğlu
Abstract: In this article, role of propolis on cytogenetic and physiological parameters in Allium cepa L. seeds exposed to salinity were studied. On the other hand, salinity showed a significant inhibitory effect on the seed germination and seedling growth of Allium cepa. Moreover, salinity reduced significantly the mitotic index in root tip cells and increased the chromosomal abnormalities and micronucleus which is the simplest indicator, the most effective of cytological damage. Althought the detrimental effects of salinity on the seed germination, mitotic activity, seedling growth and chromosomal aberrations were alleviated flashilly in varying degrees by propolis application, it was ineffective in reducing of salt damage on the micronucleus frequency.
