The scarcity of good quality water is a limiting factor for irrigated agriculture, especially in arid and semi-arid regions, and it is necessary to identify genotypes with economic potential that are tolerant to saline stress, as well as appropriate strategies for irrigation with saline water. The aim was therefore to assess the tolerance of coloured cotton genotypes to cumulative salt stress at different stages of plant development, as well as the influence of the salinity conditions in which the seeds were formed in a new cultivation cycle. Two experiments were carried out in a greenhouse,...

The use of saline water in agriculture has become a reality in many areas of the world, as tolerance to salinity varies between stages of crop development and also with the genotype used. Equally important are studies into plant recovery after exposure to salinity, which could be a strategy for using saline water in irrigation. With this in mind, the aim of this research was to determine the tolerance of naturally coloured cotton genotypes, varying the stages of plant development, under conditions of low and high salinity and to assess recovery after exposure to saline stress. In an...
