Avaliou-se a eficácia do modelo Ceres-Wheat na estimativa da produtividade e datas de florescimento e de maturidade fisiológica de trigo, cultivar IAC 24. Para comparar os valores estimados pelo modelo Ceres, utilizou-se de dados observados em ensaio de campo com trigo irrigado e adubado com diversas doses de N-fertilizante: 0, 30, 60, 90 e 120 kg ha-1 de N no primeiro ano e 0, 45, 90, 135 e 180 kg ha-1 de N no 2o ano. O modelo simulou satisfatoriamente a fenologia, os componentes do rendimento e o rendimento do trigo, inclusive o efeito da adubação nitrogenada. As estimativas das datas de florescimento e maturidade fisiológica apresentaram pequenos desvios em relação às datas observadas a campo, que se deveu à ocorrência de temperaturas médias diárias maiores do que a media histórica e consequentemente um encurtamento do ciclo da cultivar. Embora haja necessidade de refinamento na estimativa de alguns processos, os resultados indicam que o modelo CERES-Wheat é adequado para estimativas da fenologia e rendimento da cultivar de trigo IAC-24 para previsão de resposta à adubação N. |

Citrus relatives are a relevant source of valuable traits for use in citrus breeding, including resistance to diseases such as Huanglongbing (HLB). Resistant rootstocks may impact tree responses to HLB. This requires graft compatibility, which has been poorly investigated within the Aurantioideae. In this study, the biometric characteristics and the anatomy of the graft union of 86 scion/rootstock combinations were assessed. This comprised 18 genotypes/species and 8 genera from Citrinae, Balsamocitrinae, and Clauseninae subtribes sensu Swingle and Reece. Most graft combinations were found to be noncompatible. Phylogenetic proximity did not ensure successful grafting as, for example, Orange jasmine autografts failed, whereas some intergeneric grafts were successful (>60% of graft-take). Plant scion height was directly related to graft-take, but the correlation between the scion and rootstock stem diameters was not a reliable indicator of graft compatibility. Rangpur/Tabog, Tabog/Rangpur, Wampee/Rangpur, Wampee/Pomeroy, Wampee/Swingle, Pomeroy/Wampee, and Swingle/Wampee were the most compatible intergeneric graft combinations. Graft-take success for this was at similar levels to those of sweet orange grafted on common citrus rootstocks. The position as a scion or rootstock in the combination affected the performance and was specific to the genotypes tested. The lack of differentiation between xylem-derived calli and the accumulation of phenolic compounds at the graft union were clear anatomical and biochemical markers, respectively, of incompatibility for most Aurantioideae combinations. In the field, within a set of the ten most promising combinations, Hamlin/Rangpur (control) was the only one that became infected by ?Candidatus Liberibacter asiaticus?. This was first observed 12 months after planting. Overall, the assessment of biometric traits and anatomy of the graft union allowed Aurantioideae genotypes to be divided into four clusters, with respect to their graft compatibility, as follows: fully compatible with high graft-take and plant growth; potentially compatible with high graft-take but lower plant growth; partially incompatible with lower graft-take and poor plant growth; and fully incompatible with a complete absence of graft-take.
