Kernel chemical composition and flour quality of wheat in response to nitrogen sources and doses. Author(s): SOUZA, T. M.; PRANDO, A. M.; MIRANDA, M. Z. de; HIROOKA, EL. Y.; ZUCARELI, C. The chemical composition of wheat kernels (Triticum aestivum L.) directly affects the quality of flour by modifying its functional and technological properties, determining its use by the industry. Fi... ... Repository: BDPA Publication year: 2019
Urease inhibitors of agricultural interest inspired by structures of plant phenolic aldehydes. Author(s): HORTA, L. P.; MOTTA, Y. C. C.; BARBOSA, G. M.; BRAGA, T. C.; MARRIEL, I. E.; FÁTIMA, A. de; MODOLO, L. V. The plant phenolic natural products (PNPs) protocatechuic aldehyde, syringaldehyde and vanillin were used as platforms for obtaining four urease inhibitors. Urea (urease substrate) or thiourea (urease... ... Repository: BDPA Publication year: 2016
