Cutting management of dual purpose wheat and implications on seed quality

Abstract

The nutritive value of a dual purpose forage, its structural and morphological composition, seed production capacity are determining characteristics in the selection of a genotype. The objective of this work was to evaluate the effect of cutting management on yield components, physiological quality of the seeds in the subsequent generation. Experiment I: the field cutting management was performed, and the yield components and the physiological quality of the seeds were evaluated. Experiment II: where the components of plant yield and physiological quality of the seeds were evaluated. The cutting managements affect the components of yield, such as thousand seed weight and seed mass per cob, as well as germination, first germination count and seedling dry mass of dual purpose wheat. In the generation that evaluates the quality of the seeds produced, the cuts do not influence the physiological quality of the seeds, however, they affect the yield components, number of cobs per plant, one thousand seed weight and seed mass per cob.
