Abstract

  Wheat is one of the most consumed and produced cereals in the world, accounting for about 35% of world grain production. Due to genetic improvement, it is a cereal that has great capacity of adaptation to diverse edaphoclimatic conditions and resistance to abiotic factors. Among these, one of the factors of greatest concern in agriculture is soil salinity, which causes the reduction of plant development, and consequently impairs its production. In this context, the objective of this work was to study the influence of salinity on germination and initial growth of wheat seedlings. Throughout the simulation of saline stress, wheat seeds from cultivar IPR Catuara TM were used, and tested the following concentrations of NaCl: 0; 15; 30; 45; 100 e 200 mmol L-1. The following determinations were analyzed: germination, length and dry mass of seedlings. For the statistical analysis, the statistical design was applied in a completely randomized design, with four replicates of 50 seeds, submitting the data to regression analysis. From the obtained results it can be concluded that: Up to the dose 100 mmol L-1 of NaCl, the germinative power of the seeds is above 80%; The seedling length is affected from 30 mmol L-1 and the seedling dry mass from 100 mmol L-1, the dose 200 mmol L-1 of NaCl was considered extremely harmful for the initial growth of the culture.
