Haploids in maize are selected through visual analysis, whether by use of expression of the R1-navajo marker in seeds, or by the phenotype of haploid plants in the field. These methods of identification of haploid plants demand space, resources, and time. Near infrared spectroscopy (NIR), together with multivariate calibration methods, is an alternative for identification of haploid seeds and plants in a quick and accurate way. The aim of the present study was to use NIR to classify haploid and diploid seeds and differentiate haploid, doubled haploid, and diploid plants originating from different genotypes used as donor. In the first experiment, haploid and diploid maize seeds were analyzed from four genotypes used as parents. In another experiment, diploid, haploid, and doubled haploid plants from 34 source populations were evaluated and differentiated. Spectral data were collected from all the seed and leaf samples using the portable MicroNIR device. Then the data were preprocessed by principal component analysis and by partial least squares discriminant analysis (PLS-DA). The use of the portable MicroNIR, together with the PLS-DA method, enabled classification of haploid and diploid seeds and haploid, doubled haploid, and diploid plants with 100% accuracy, constituting a fast, simple, nondestructive, and reliable methodology for identification of haploids in maize, and it is more effective than the visual analysis. |

The objective of this work was to characterize condensed tannins (CT) from six tropical forage legumes and to determine their biological activity. The monomers propelargonidin, prodelphinidin and procyanidin were analyzed, as well as extractable condensed tannin (ECT), protein-bound CT (PBCT) and fiber-bound CT (FBCT), molecular weight, degree of polymerization, polydispersity index, and biological activity by protein precipitate by phenols (PPP) of leaves of the legumes Cajanus cajan, Gliricidia sepium, Stylosanthes capitata x Stylosanthes macrocephala (stylo), Flemingia macrophylla, Cratylia argentea, and Mimosa caesalpiniifolia, and of the bark of this latter species. Differences were observed in the concentrations of ECT, PBCT, PPP, and total condensed tannin among species, but not in that of FBCT. The highest value of PBCT occurred in F. macrophylla. Total CT varied from nondetected concentration in C. argentea to the highest concentration in M. caesalpiniifolia leaves that contain the greatest levels of PPP. No differences were observed for polymerization degree in stylo, F. macrophylla, and M. caesalpiniifolia. Leaves of stylo, C. cajan, and G. sepium, all containing between 20 and 50 g kg-1 total CT, should be beneficial CT sources, if offered as sole feeds in ruminant diets. The ratio of prodelphinidin:procyanidin varies from 10:80 (stylo) to 65:35 (F. machrophylla), and propelargonidin is only determined in C. argentea. |
