Microsporogenesis in Brachiaria dictyoneura (Fig. & De Not.) Stapf (Poaceae: Paniceae).
Microsporogenesis was analyzed in five accessions of Brachiaria dictyoneura presenting x = 6 as the basic chromosome number. All accessions were tetraploid (2n = 4x = 24) with chromosome pairing in bi-, tri-, and quadrivalents. The recorded meiotic abnormalities were those typical of polyploids, including precocious chromosome migration to the poles, laggard chromosomes, and micronucleus format...
متن کاملColheita, beneficiamento e controle de qualidade de sementes de nabo forrageiro
The oil radish siliques maturation occurs in a non-uniform way, which makes it difficult to define the ideal harvesting time in order to produce high quality seeds. In addition, the high lipid content of the seed may hamper its preservation. To evaluate the effect of the maturation stage at harvesting on the physiological quality and chemical composition of the oil radish seeds stored under dif...
