Pinus taeda (loblolly pine) is a widely-cultivated conifer that is particularly prevalent in the southeast United States and Southern Brazil. Some companies in Brazil are working with the third generation of improvement and other clonal tests of this species. The present study analyzed the interaction of genotype ×environment (G ×E) in clonal tests of loblolly pine planted in the South and Southeast regions of Brazil. For this, 75 clones and three commercial controls were tested using a randomized block design, with eight replications, and one plant per plot repeated across four sites. Measurements were performed at 11 years of age for diameter at breast height (dbh), total height, and volume. The GGE biplot and the Harmonic Mean of the Relative Performance of Genotypic Values (MHPRVG) methods were used to study the effects of G×E on dbh. The dbh was chosen because it is less subject to measurement errors and highly correlated with volume. The mean of heritability in the broad-sense among sites for dbh was high (0.89), as was the genotypic correlation between sites (0.78). Among the four tested environments, two sites can be considered as one mega-environment. Through the analysis, it was possible to verify the low magnitude of the effects of G × E on the tested clones. The best performing clones among all tests can be selected to produce commercial stands in areas with similar environmental characteristics to the sites tested herein. Thus, the composition of two breeding zones is recommended considering the tested clones.

RESUMO: O girassol é uma oleaginosa de destaque entre as culturas utilizadas em sucessão à soja na região dos cerrados. No entanto, poucas informações referentes aos efeitos da atividade residual de herbicidas aplicados na soja sobre o desenvolvimento e rendimento do girassol são conhecidas. Visando avaliar a atividade residual de herbicidas, aplicados em pré e pós-emergência na cultura da soja sobre o girassol cultivado em sucessão, foram conduzidos ensaios em campo e em casa de vegetação. No ensaio de campo, foram empregados nove tratamentos (doses em kg de i.a. ha-1): imazaquin (0,161), diclosulam (0,035), sulfentrazone (0,600) e flumioxazin (0,050), em aplicações de pré-emergência, e chlorimuronethyl (0,015), imazethapyr (0,060), imazethapyr (0,100) e fomesafen (0,250), aplicados em pós-emergência da soja, mais uma testemunha (sem herbicida). Um bioensaio foi conduzido em casa de vegetação com as amostras de solo dos tratamentos coletadas em seis épocas distintas (0, 35, 70, 105, 140 e 200 dias após a aplicação). Os resultados permitem concluir que o imazethapyr (0,100kg ha-1) e o diclosulam (0,035kg ha-1) causam redução no rendimento do girassol. A sensibilidade ao diclosulam perdura durante todo o cultivo do girassol. ABSTRACT: Bioactivity of herbicides used to soybean on sunflower crop in succession. The sunflower is a oilseed crop kind of prominence before the cultures used in succession in the Brazil. However, little information concerning the effects of residual activity of herbicides on the crop in this region are known. The aim of this study was to evaluate the residual activity of herbicides in weed management in pre and post-emergence soybean and evaluate its effects on sunflower crop in succession. In field experiments we adopted the randomized block design with four replications, being appointed nine treatments (kg of i.a. ha-1): imazaquin (0.161), diclosulan (0.035), sulfentrazone (0.600) and flumioxazin (0.050) in pre emergence applications, and chlorimuron-ethyl (0.015), imazethapyr (0.060), imazethapyr (0.100) and fomesafen (0.250) applied post emergence soybean and a control without herbicide. One bioassay was differentiated by the treatments contained in each treatment and soil samples collected at six different times (0, 35, 70, 105, 140 and 200 days after application); evaluated the dry matter accumulation of sunflower plants as a function of time of sample collection. The results showed that: imazethapyr (0.1kg ha-1) and diclosulan (0.035kg ha-1) caused a reduction in sunflower yield. Sensitivity to diclosulan continued throughout the interval evaluation of the range of bioassay.
