The protective effect of jasmonic acid (JA) was evaluated under the stress conditions (100 mM NaCl). The potato plants
Solanum tuberosum
L, mid-season variety Lugovskoy, were used in the experiments. The plant-regenerants were grafted and grown in test tubes on the modified Murashige and Skoog agar medium in the absence (control) or presence of JA at concentrations of 0.001, 0.1, and 10 μM under the optimal conditions or with addition of NaCl. After 28 days of cultivation, the growth (stem and root lengths, tier and leaf numbers, and plant mass) and physiological (proline and photosynthetic pigment contents and teh osmotic potential of cell exudate) characteristics of the plants were assessed. Jasmonic acid (0.1 and 10 μM) has been demonstrated to display a pronounced protective effect on potato plants under the salt stress condition. JA abolished partially the negative salt effect on the main photosynthetic pigments and maintained the cell osmotic status during salinization.
