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.
两用小麦刈割管理及其对种子品质的影响
双重用途牧草的营养价值、结构和形态组成、制种能力是基因型选择的决定性特征。本研究的目的是评价刈割管理对后代种子产量组成和生理品质的影响。试验一:进行田间刈割管理,评价种子的产量构成和生理品质。实验二:评价植株产量和种子生理品质的组成部分。刈割管理对双料小麦千粒重、每芯粒重、发芽率、初发芽数和幼苗干质量等产量组成有影响。在评价所产种子质量的世代中,刈割不影响种子的生理品质,但影响产量组成、单株穗轴数、千粒重和每穗粒重。
