The calculation of node appearance is an important part of simulation models of crops with decumbent growth habit like muskmelon (Cucumis melo L.). The objective of this study was to adapt and evaluate a multiplicative non-linear model for estimating node appearance in muskmelon under greenhouse conditions. A series of experiments were conducted inside a plastic greenhouse in Santa Maria, RS, Brazil, using the muskmelon hybrid HY-MARK. A total of eleven planting dates were performed during 2002, 2003, and 2004. The number of visible nodes (NN) on the main vine was evaluated twice a week. The NN data from three planting dates were used to estimate the coefficients of the non-linear model and the plastochron (linear model), used as a comparison model. The NN data from the other eight planting dates were used as independent data for evaluating the models. The non-linear model had a good performance in simulating the main vine node number in this muskmelon hybrid, with a root mean square error of 2.4 nodes. The non-linear model was superior to the linear model as deviations (predicted-observed) were greater with the latter compared to the former model. |

The objective of this work was to estimate the incidence and prevalence of Garlic common latent virus (GarCLV) in the main production regions of garlic (Allium sativum) in Argentina, and to perform phylogenetic and recombination analyses in isolates from these regions. Leaf samples (3,050) were taken from four garlic commercial types, in 13 departments of the four main garlic‑producing provinces of Argentina, in a 1,175‑ha sampling area. Virus infection was evaluated with DAS‑Elisa test using specific antiserum, and the phylogenetic and recombination analyses were done with capsid protein (CP) nucleotide sequence of seven GarCLV isolates from the provinces. The incidence of GarCLV in the evaluated provinces varied between 6.7 and 22% of the samples, whereas the prevalence varied between 52.6 and 70%. In the analysis of garlic commercial types, Morado showed the highest incidence of the virus, in the province of San Juan, whereas Rosado Paraguayo had the lowest incidence, in the province of Cordoba. Nucleotide identity in the CP sequences ranged between 80.3 and 97.6%. The phylogenetic analysis shows the presence of two main groups of GarCLV and of a possible third group that would include only a German isolate. The recombination analysis between isolates from different parts of the world evidences the presence of recombinant isolates from Poland and Australia. |
