A baixa intensidade luminosa reduz a produção de fotoassimilados pelas plantas e consequentemente o acúmulo reservas nas sementes. Objetivou-se avaliar qualidade fisiológica sementes soja produzidas sob sombreamento iniciado em diferentes estádios fenológicos da cultura. O experimento foi conduzido casa vegetação, no CAV/UDESC, durante safra 2018/2019, delineamento inteiramente casualizado, com...

Soybeans often encounter several in-season stressors that can alter retention of reproductive structures. To understand soybean response to structural losses through altered growth parameters—and, ultimately, yield—a field trial was established in Bixby, Oklahoma, 2019 and 2020 Perkins, 2019. Removal structures occurred at full flower (R2), the beginning pod development (R3), seed (R5) three lo...

I graduated from tuition-free College of the City of New York (CCNY) in 1933. At that time the country was in the depths of the Great Depression, and there were few positions available for City College graduates. Its students were mainly children of immigrants who were bright and highly motivated. CCNY graduates included eight future Nobel Prize awardees and several distinguished biochemists. A...

tion and nodulation, thus reducing N2 fixation capacity (Shibles, 1998). Application of N before planting or durNitrogen application during soybean [Glycine max (L.) Merrill] ing the early growth stages can suppress the N2 fixation reproductive stages has the potential to increase soybean productivity. The objective of this study was to determine the impact of N fertilizer process. Fertilizer N...

Fragment based Quantitative structure activity relationship (QSAR) analysis on reported 25 2-(2-(4-aryloxybenzylidene) hydrazinyl) benzothiazole dataset as antitubercular agents were carried out. Molecules in the current dataset were fragmented into six fragments (R1, R2, R3, R4, R5, R6).Group based QSAR Models were derived using Multiple linear regression (MLR) analysis and selected on the bas...

The eight photoreceptors in each ommatidium of the Drosophila eye are assembled by a process of recruitment [1,2]. First, the R8 cell is singled out, and then subsequent photoreceptors are added in pairs (R2 and R5, R3 and R4, R1 and R6) until the final R7 cell acquires a neuronal fate. R7 development requires the Sevenless receptor tyrosine kinase which is activated by a ligand from R8 [3]. He...

Knowledge on movement and spatial patterns of insect pest populations among preferred hosts aids in the development of effective pest management strategies. In this study, we quantified the spatiotemporal dynamics of the invasive brown marmorated stink bug, Halyomorpha halys (Stål 1855), in relation to field corn, Zea mays L., and soybean, Glycine max (L.), crop phenology. We also examined the ...
