El objetivo de este trabajo fue analizar la acumulación, removilización, absorción postantesis y la eficiencia en la utilización de N bajo dos sistemas de labranza (reja y cincel) y diferentes tipos de fertilización, en los cultivares de trigo pan Buck Pronto y Buck Charrúa. Los tratamientos de fertilización fueron: testigo sin el agregado de N, aplicación de 90 kg ha-1 de N como urea a la siembra, aplicación de 90 kg ha-1 de N como nitrato de amonio calcáreo a la siembra y aplicación de N como urea y como nitrato de amonio calcáreo en dosis de 45 kg ha-1 a la siembra más 45 kg ha-1 a fin de macollaje, respectivamente. Se encontraron diferencias en el N acumulado entre sistemas de labranzas; con cincel se acumuló 18 kg ha-1 más que bajo reja, pero esto no se tradujo en el porcentaje de N contribuido al grano por removilización ni por absorción postantesis. La fertilización aumentó el N acumulado en un promedio de 50 kg ha-1. A su vez provocó un aumento en la contribución al grano del N removilizado, pero no mejoró el aporte del N absorbido postantesis, ni aún en la aplicación en dos momentos. Los cultivares presentaron diferencias en el N acumulado y en el porcentaje aportado al grano por removilización y absorción postantesis. La eficiencia de utilización del N dependió de la labranza y de la fertilización. |

This study presents the status of ex situ and in situ conservation for the crop wild relatives of rice, potato, sweet potato, and finger millet in Brazil, and the subsequent germplasm collection expeditions. This research is part of a global initiative entitled "Adapting Agriculture to Climate Change: Collecting, Protecting, and Preparing Crop Wild Relatives" supported by the Global Crop Diversity Trust. Species of the primary, secondary, and tertiary gene pools with occurrences reported in Brazil were included: Oryza alta Swallen, O. grandiglumis (Döll) Prod., O. latifolia Desv., O. glumaepatula Steud., Eleusine tristachya (Lam.) Lam., E. indica (L.) Gaertn., Solanum commersonii Dunal, S. chacoense Bitter, Ipomoea grandifolia (Dammer) O?Donell, I. ramosissima (Poir.) Choisy, I. tiliacea (Willd.) Choisy, I. triloba L., and I. cynanchifolia Meisn. The status of the ex situ and in situ conservation of each taxon was assessed using the gap analysis methodology, and the results were used to plan 16 germplasm collection expeditions. Seeds of the collected material were evaluated for viability, and the protocols for seed germination and cryopreservation were tested. The final conservation score, resulting from the gap analysis and including the average of the ex situ and in situ scores, resulted in a classification of medium priority of conservation for all the species, with the exception of I. grandifolia (high priority). The total accessions collected (174) almost doubled the total accessions of these crop wild relatives incorporated in Embrapa's ex situ conservation system prior to 2015. In addition, accessions for practically absent species were collected for the ex situ conservation system, such as Ipomoea species, Eleusine indica, and Solanum chacoense. The methods used for dormancy breaking and low temperature conservation for the Oryza, Eleusine, and Ipomoea species were promising for the incorporation of accessions in the respective gene banks. The results show the importance of efforts to collect and conserve ex situ crop wild relatives in Brazil based on previous gap analysis. The complementarity with the in situ strategy also appears to be very promising in the country.
