INTERACTIVE EFFECTS OF SALINITY STRESS WITH OR WITHOUT NICOTINAMIDE ON PHYSIOLOGICAL AND BIOCHEMICAL PARAMETERS OF TOMATO SEEDLING
Journal Title: Folia Pomeranae Universitatis Technologiae Stetinensis Agricultura Alimentaria Piscaria et Zootechnica - Year 2016, Vol 38, Issue 326
Abstract
The aim of this study is to determine the effect of both NaCl and KCl salt alone or in combination with nicotinamide, on growth and some biochemical parameters of Vilma cultivar of tomato under laboratory and field conditions. The combinations of salt solutions used ha a negative impact on the ability of seed germination and morphological characteristics of 14-day-old tomato seedlings. The addition of NaCl salt had a positive impact on the content of Chl a and Car in contrast KCl salt solution led to the decrease of photosynthetic and non- -photosynthetic pigments. Under field conditions, NaCl salt solution exhibited inhibitory effect on plant growth, concentration of Chl a, Chl b, and Car, simultaneously increasing oxidative stress parameters (proline and malondialdehyde – MDA). Moreover, leaves of tomato from the control group were darker in comparison to the remaining plants. It was observed that the addition of nicotinamide to the solution did not show protective effect on plants grown under salinity, except in a small increase of the concentration of proline.<br/><br/>
