Five bean cv. were exposed to natural daylength (approx. 12 h) and ambient temp., or to 6 h daylength, achieved by moving pots into a darkened room to determine their response to photoperiod. Cv. Mortino and Frijolica 0- 3.2 did not flower under the control conditions, but with the short day trea...

Mediram-se o rendimento e a qualidade de sementes das plantas e desprendidas, através de amostragens durante a fase de maturação em S. macrocephala, em Carimágua, Colômbia, no ano de 1983. O delineamento foi o de blocos casualizados com quatro repetições. As amostragens foram semanais entre 57 e ...

Photoperiod response of flowering in common bean (Phaseolus vulgaris L.) is thought to be controlled by the genes Ppd and Hr. However, cultivars also vary in the degree that cooler temperatures reduces their sensitivity to photoperiod. To examine the inheritance of this temperature sensitivity, c...

No Brasil, o potencial para o estabelecimento de uma exploração expecializada em produção de sementes de forrageiras é considerável. Para que estes produtores de sementes obtenham êxito em seu empreendimento é necessário que eles se estabeleçam em regiões ideais para esta atividade agrícola. Nest...

For a proper characterization of beans, as well as for future improvements in basic yield potential, it is necessary to understand the process of node formation on stems and the evolution of the axils, either vegetative or floral, at these nodes. Within a pure nonphotoperiodic var. of Phaseolus v...
