AB  - Cereal seeds safety may be compromised by the presence of toxic contaminants, such as aflatoxins.
Besides being carcinogenic, they have other adverse health effects on humans and animals. In
this preliminary study, we used two non‑invasive optical techniques, optical fiber fluorescence
spectroscopy and multispectral imaging (MSI), for discrimination of maize seeds naturally
contaminated with aflatoxin B 1 (AFB 1 ) from the uncontaminated seeds. The AFB 1‑contaminated
seeds exhibited a red shift of the emission maximum position compared to the control samples.
Using linear discrimination analysis to analyse fluorescence data, classification accuracy of 100%
was obtained to discriminate uncontaminated and AFB 1‑contaminated seeds. The MSI analysis
combined with a normalized canonical discriminant analysis, provided spectral and spatial patterns
of the analysed seeds. The AFB 1‑contaminated seeds showed a 7.9 to 9.6‑fold increase in the seed
reflectance in the VIS region, and 10.4 and 12.2‑fold increase in the NIR spectral region, compared
with the uncontaminated seeds. Thus the MSI method classified successfully contaminated from
uncontaminated seeds with high accuracy. The results may have an impact on development of
spectroscopic non‑invasive methods for detection of AFs presence in seeds, providing valuable
information for the assessment of seed adulteration in the field of food forensics and food safety.

AB  - The aim of this study was to observe direct and joint effects of three factors (genotypes,
ecological environmental conditions and the applied crop density) on the level of defoliation intensity
and yield. Three inbred lines (G) of maize (G1–L217RfC, G2–L335/99 and G3–L76B004) were used
in the study. The trials were performed in two years (Y) (Y1 = 2016 and Y2 = 2017) and in two
locations (L) (L1 and L2) under four ecological conditions of the year–location interaction (E1–E4)
and in two densities (D1 and D2) (50,000 and 65,000 plants ha−1
). Prior to tasselling, the following
five treatments of detasseling and defoliation (T) were applied: T1—control, no leaf removal only
detasseling, T2–T5—removal of tassels and top leaves (from one to four top leaves). The defoliation
treatments had the most pronounced effect on the yield reduction in G1 (T1–Tn+1 . . . T5), p < 0.05.
The ecological conditions on yield variability were expressed under poor weather conditions (E3 and
E4), while lower densities were less favorable for the application of defoliation treatments. The result
of joint effects of factors was the lowest grain yield (896 kg/ha) in G3 in the variant E3D1 for T2 and
the highest grain yield (11,389 kg/ha) in G3 in the variant E2D2 for T1. The smallest effect of the
defoliation treatment was on the kernel row number (KRN)
