Abstract

Wheat dual purpose (Triticum aestivum L.) has elevated biomass production, high tillering potential, long vegetative stage, short reproductive period. Therefore, this study aim to reveal the seeding rates effect on physiological attributes of wheat dual purpose seeds grown in three agricultural crops, and identify a population management strategy and check the response stability of the traits in southern Brazil. The tests were carried out during 2012, 2013 and 2014 agricultural crops. The experimental design was randomized blocks arranged in factorial scheme, being: three agricultural crops x two wheat genotypes dual purpose (BRS Tarumã and BRS Umbu) x five seeding rates (75, 150, 225, 300, 375 seeds m-2), arranged in three repetitions. The variance analysis revealed significant interaction to p>0.05 of probability for agricultural crops x dual purpose wheat genotypes x seeding rates for the characters first germination counting (FGC), germinated seeds percentage (GP), seedlings dry mass (SDM), and field emergence (FE). The genotype BRS Tarumã with increases of seeding rates, reduced the magnitude of germination and first germination counting in all agricultural crops. For wheat dual purpose seedling dry mass and field emergence decreased with seeding rates increment. Management strategies to improve the physiological quality of seeds wheat with dual purpose are specific to agricultural crops, providing applications in scientific research and as agricultural.
