Assessment of 1-Triacontanol treatment of sweet corn (Zea mays L. convar. saccharata) aimed at the improvement of salt tolerance based on a pot experiment

Abstract

In our research, the salt stress of two sweet corn hybrids (Tyson and Sweetstar) was induced by irrigation with saline water in a pot experiment. We studied the possibility of the decrease of the negative effects of salt stress by applying 1-Triacontanol (TRIA) in various (3, 6, and 9 μM) doses. Plant height, raw biomass, root biomass, parameters characterizing the photosynthetic activity (SPAD, NDVI, chlorophyll content), and proline content were determined in order to quantify the effect of the TRIA treatment on salt tolerance. We concluded that triacontanol treatments had a positive effect on the studied parameters of both hybrids.
