Keller-Grein, Gerhard[Caracterización y evaluación agronómica de germoplasma de nuevas leguminosas forrajeras tropicales]Caracterización y evaluación agronómica de germoplasma de nuevas leguminosas forrajeras tropicales

With graphs, illustrations, photos, and tables, the utilization of tissue culture techniques for the conservation and international exchange of cassava is briefly described. Likewise, the results of the phenotypic stability of cassava cv. M. Mex 20, M. Col 650, M. Col 2197, CM 305-38, and CM 323-...


Roca, William M.Narvaez, JRodríguez, J.Reyes, R.Mafla, G.Beltran, J.Roa E, J.C.Ramírez, H.Rodríguez, A.M.[Utilization of tissue culture techniques for the conservation and international exchange of cassava (Manihot esculenta) germplasm]Utilization of tissue culture techniques for the conservation and international exchange of cassava (Manihot esculenta) germplasm

Plant tissue culture includes a wide range of techniques: protoplast, cell, anther, callus, meristem and organ culture, all having one common factor: the growth of vegetative material in an aseptic environment; i,e., the sterilized culture medium in test tubes. In spite of the fact that several o...

A scale of stages of development of the bean plant applicable to both determinate and indeterminate growth types is defined and described. It consists of 10 critical phenological steps comprised into 2 phases: one vegetative (V) and the other reproductive (R). The stages V 0 (germination), V 1 (e...


Fernández, F.Gepts, Paul L.[A scale of development stages of the bean plant Phaseolus vulgaris. A summary for consultation]A scale of development stages of the bean plant Phaseolus vulgaris. A summary for consultation

Different assays on climbing beans in relay cropping or associated with maize, N fixation and Rhizobium inoculation, and bush beans in monoculture are reported. These were conducted in La Selva, Antioquia (Colombia), through a collaborative project between the Instituto Colombiano Agropecuario (I...

IBYAN = International Bean Yield and Adaptation Nursery (Phaseolus vulgaris L.): Frijol arbustivo (bush beans) - (1976-1987)]Vivero Internacional de Rendimiento y Adaptacion de Frijol (Phaseolus vulgaris L.) IBYAN = International Bean Yield and Adaptation Nursery (Phaseolus vulgaris L.): Frijol arbustivo (bush beans) - (1976-1987)

Some basic concepts of physiology are presented in relation to bean cultivation, and the external and internal factors affecting crop development and production are described: the environment (edaphic and climatic factors), photosynthesis and factors that affect it (light, CO2, O, temp., wind and...
