Effects Of Salt Stress Of The Respiratory Components Of Some Plants, N.A. Kasumov, Z.I. Abbasova, G. Gündüz
Turkish Journal of Botany
Oxygen absorption, kinetic regularities of free radical oxidation and anti-oxidation activity were studied in roots and isolated mitochondria for various groups of plants under salt stress of NaCl, Na 2 SO 4 and Na 2 CO 3 . The results show that spearation of oxidation and phosphorylation obviously stimulates the oxygen absorption by plants under salt strees. Therefore, the anti-oxidation activity of roots decreases abruptly, resulting in an uncontrolled acceleration of free radical processes. The obtained data is a definite contribution to the concept concerning the toxic effect of salt on plants.

The effects of Polystimuline K (PS-K), as a cytokinin analogue, on delayed light component state (DF), intermittent fluorescence (IF) and chlorophyll (Chl) a/b ratio was investigated in the leaves of different genotypes of cotton ( Gossypium hirsutum L.) under salt stress (155 mM Na Cl) for different periods of time. It was shown that in the early perioid of salt stress, DF and IF amplitudes are decreased, which is indicative of a Photosystem II (PS II) activity decrease. It is possibly related to the damage of chlorophyll in the PS II donor site and the decrease of Chl b molecules …
