Dois ensaios de girassol foram conduzidos na safrinha 2011 com objetivo de avaliar genótipos mais adaptados às condições de cerrado de Rondônia e regiões adjacentes de Mato Grosso. Os ensaios foram instalados no Campo Experimental de Vilhena, da Embrapa Rondônia (12º45? S e 60º08? W, 600m de altitude), em blocos casualizados, com 10 tratamentos e quatro repetições, em duas épocas de semeadura, com intervalo de 18 dias. Foram avaliadas as variáveis: produtividade, população final de plantas, altura de plantas, dias para florescimento e dias para maturação. Foram observadas diferenças estatísticas para todas as variáveis avaliadas, confirmando a necessidade e a importância de se avaliar diferentes genótipos de girassol para o cerrado de Rondônia e regiões adjacentes do estado de Mato Grosso, visando selecionar os mais adequados para cultivo. Os genótipos que mais se destacaram, considerando as duas épocas de semeadura, foram o CF 101, V70004 e a testemunha M 734. SUNFLOWER GENOTYPES EVALUATION FOR RONDONIA AND MATO GROSSO SAVANNA:NATIONAL NETWORK - FINAL 2. Two sunflower trials were carried out to evaluate more adapted genotypes to Rondonia savanna condictions and neighboring regions of Mato Grosso State. The trials were installed in Vilhena Experimental Station, of Embrapa Rondonia (12º45? S, 60º08? W, 600m altitude), in a completely randomized blocks design, with 10 treatments and four replications, in two sowing dates, 18 days spaced. Grain yield, stand, plants height, days for flowering and days for maturation were evaluated. In both sowing dates, all parameters showed statistical difference, confirming the necessity and importance of sunflower genotypes evaluation to select those more adapted to Rondonia and Mato Grosso savanna conditions. CF101, V70004 and M 734 genotypes showed the best results in the two sowing seasons.

In the common bean (Phaseolus vulgaris L.), premature nodule senescence affects biological nitrogen fixation (BNF), reducing crop yield. Here, we investigated the molecular and biochemical changes in common bean nodules undergoing aging senescence. The experiments were carried out with three common bean genotypes and two nodule groups: senescent and non-senescent nodules. The expression patterns of 12 genes were assessed using RT-qPCR. In addition, global activities of ascorbate peroxidase (APX) and catalase (CAT), lipid peroxidation and total sugar content of nodules were also determined. Our results show that PvLb gene expression was down-regulated and PvGS(n-1) and PvUriII, genes involved in N metabolism, also decreased in senescent nodules. Transcripts related to the ethylene, abscisic acid and cytokinin phytohormones were up-regulated upon nodule senescence. Interestingly, PvSnakin-2 (SNAKIN-like cysteine rich protein), a gene related to plant-pathogen interaction, was induced in senescent nodules. The biochemical assays showed that in nodules undergoing senescence, APX activity was altered in only one genotype but CAT activity decreased in all common bean genotypes. Lipid peroxidation increased but total sugar content was not altered in nodules upon senescence. All these findings suggest that a delayed plant-response to Rhizobium infection is activated in common bean nodules undergoing aging senescence and this mechanism seems to be regulated by phytohormones and cell signaling as well, whereas the antioxidant defenses mediated by CAT are repressed, suggesting oxidative damage in nodules upon senescence. Our results offer insights into understanding nodule senescence metabolism and provide potential senescence markers for common bean nodules.
