Title: Identification of haploid maize by flow cytometry, morphological and molecular markers.
Título: Identificação de milho haploide por citometria de fluxo, marcadores morfológicos e moleculares.

Authors: COUTO, E. G. de O.; DAVIDE, L. M. C.; BUSTAMANTE, F. de O., PINHO, R. G. V.; SILVA, T. N.

Abstract:

The development of homozygous breeding lines in maize may be accelerated through the use of haploids. Thus, the obtaining and prior identification of haploids generated by the haploid inducer lines is an important factor. T...

Title: Physiological quality and amylase enzyme expression in maize seeds.
Título: Qualidade fisiológica e expressão das enzimas amilases em sementes de milho.

Authors: OLIVEIRA, G. E.; PINHO, R. G. V.; ANDRADE,T. de; PINHO, E. V. de R. V.; SANTOS, C. D. dos; VEIGA, A. D.

Abstract:

The physiological quality of maize seeds is affected by the genotype. Thus, the study of expression of genes associated with this characteristic is important in the genotype selection process in breeding programs. The aim o...

Title: Pedotransfer functions for water retention in different soil classes from the center-southern Rio Grande do Sul State.
Título: Funções de pedotransferência para retenção de água em diferentes classes de solos no centro-sul do estado do Rio Grande do Sul.

Authors: SANTOS,W. J. R. dos; CURI, N.; SILVA,S. H. G.; ARAÚJO, E. F. de; MARQUES, J. J.

Abstract:

Water retention in soil is used in many agronomic and environmental applications, but its direct measurement is time-consuming and expensive. Therefore, pedotransfer functions (PTFs) are alternatives to obtain this informat...
