Salt stress is one of the most limiting environmental factors for agricultural yields in the Semiarid region of Brazil. Considering the expansion of areas with sugarcane crops in this region, the selection of more adapted plant varieties to this environment is an essential tool for the sustainability of this activity. Thus, the objective of the present work was to evaluate the physiological and biochemical responses of plants of ten sugarcane varieties to salt stress. The experiment was conducted in a greenhouse using a randomized block design, in a 6×10 factorial arrangement consisting of six salinity levels in the irrigation water (0, 1.0, 2.0, 4.0, 6.0, and 8.0 dS m-1) and ten sugarcane varieties (VAT 90212, RB 72454, RB 867515, Q 124, RB 961003, RB 957508, SP 791011, RB 835089, RB 92579, and SP 943206), with three replications. Salt waters were applied every two days to increase the soil moisture to field capacity and promote leaching. The gas exchange, chlorophyll content, and total soluble and reducing sugars of leaves were evaluated at 90 days after planting. The highest chlorophyll contents were found in plants of the varieties Q 124, RB 96103, RB 835089, and SP 943206. The effect of salinity on the sugarcane plants affected their leaf gas exchanges and total soluble and reducing sugar contents, denoting the adaptability of plants to the stress conditions evaluated. The decrease of stomatal conductance resulted in decreases in photosynthetic rates in plants of all sugarcane varieties evaluated, except for RB 867515 MenosSalt stress is one of the most limiting environmental factors for agricultural yields in the Semiarid region of Brazil.

O sucesso na produção de sementes de amendoim forrageiro depende de diversos fatores que podem contribuir ou restringir a germinação, o estabelecimento e crescimento rápido das plantas e o acúmulo de um banco de sementes no solo que proporcione elevada produtividade de sementes de boa qualidade no menor período de tempo. O desenvolvimento da cultivar BRS Mandobi e do seu sistema de produção de sementes tem o objetivo de viabilizar a oferta de sementes de qualidade a preços acessíveis aos produtores no mercado nacional e internacional, de forma a permitir a utilização em larga escala dessa leguminosa nos sistemas de produção pecuários em ambientes tropicais. |
