Resumo: Sugarcane (Saccharum spp.) is an important crop due to sugar, ethanol and bioenergy production. Its cultivation may occur in tropical regions exposed to high salinity. The aim was to identify cultivars tolerant to salinity to allow the cultivation of sugarcane (Saccharum spp.) in saline soils. To test the hypothesis that sugarcane show natural genotypic variation to salinity tolerance, we tested ten cultivars (SP80-3280, RB855453 RB966928, RB855156, SP80-1842, SP80-1816, RB928064, RB867515, RB92579, RB855536) and two sugarcane species: IM76-228 (S. robustum) and IN84-82 (S. spontaneum) under two concentrations of sodium chloride (NaCl): control (concentration found naturally in the soil used: electrical conductivity of 0.083 dS m-1) and soil enriched with NaCl: EC of 7.2 dS m-1. Biometry and photosynthesis traits were evaluated. The plants were collected and leaf (LDM), stem (SDM), root and total dry matter were used to estimate the tolerance index (TI). A cluster analysis was done to identify phenotypic dissimilarity. Three distinct groups regarding salinity tolerance on biomass-basis were formed. The cultivars RB855156, SP80-1842, SP80-1816 and species IM76-228 showed no reduction in LDM and SDM. Nonetheless, the cultivars SP80-3280, RB928064, RB92579 and species IN84-82 were impaired by salinity. The cultivar SP80-1816 showed the highest biomass accumulation and the highest TI. Therefore, we found a great genotypic variation regarding salinity tolerance in sugarcane, which can be explored by growers to cultivate in saline soils. Also can be used by the Sugarcane Breeding Programs to improve the salinity tolerance.

Seu cultivo ocorre em regiões tropicais, sendo muitas vezes exposta a alta salinidade. O objetivo foi identificar cultivares tolerantes à salinidade para permitir o cultivo da cana-de-açúcar (Saccharum spp.) em solos salinos. Para testar a hipótese de que a cana-de-açúcar apresenta variação genotípica natural para tolerância à salinidade, testamos dez cultivares (SP80-3280, RB855453 RB966928, RB855156, SP80-1842, SP80-1816, RB928064, RB867515, RB92579, RB855536) e duas espécies de cana-de-açúcar: IM76-228 (S. robustum) e IN84-82 (S. spontaneum) sob duas concentrações de sódio: controle [concentração encontrada naturalmente no solo utilizado: condutividade elétrica de 0,083 dS m-1] e solo enriquecido com NaCl: CE de 7,2 dS m-1. Características de biometria e fotossíntese foram avaliadas. As plantas foram coletadas, separadas em folha (MSF), caule (MSC), raiz para determinação da matéria seca total da planta e assim estimar o índice de tolerância (IT). Uma análise de cluster foi feita para identificar a dissimilaridade fenotípica. Três grupos distintos em relação à tolerância à salinidade com base na biomassa foram formados. As cultivares RB855156, SP80-1842, SP80-1816 e espécies IM76-228 não apresentaram redução em MSF e MSC. No entanto, as cultivares SP80-3280, RB928064, RB92579 e as espécies IN84-82 foram prejudicadas pela salinidade. O genótipo SP80-1816 apresentou o maior acúmulo de biomassa e o maior IT. Portanto, encontramos uma grande variação genotípica quanto à tolerância à salinidade em cana-de-açúcar, que pode ser explorada pelos produtores para cultivo em solos salinos. Também podem ser utilizadas pelos Programas de Melhoramento da Cana-de-Açúcar para melhorar a tolerância à salinidade.Universidade Federal de Lavras2022-08-15T19:37:53Z2022-08-15T19:37:53Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfZULMA, A.
