AB  - The aim of our study was to evaluate the use of Raman spectroscopy for pre-diagnostic estimation of weed response to bleaching herbicides. Model plants were Chenopodium album and Abutilon theophrasti treated with mesotrione (120 g a.i. ha−1). Raman single-point measurements were taken 1, 2, 3, and 7 days after herbicide application from different points on the leaves. Principal component analysis (PCA) was carried out on data normalized by the highest intensity band at 1522 cm−1 and using spectral region from 950 to 1650 cm−1 comprising mainly contributions of carotenoids. The carotenoids by intensive band at ∼1522 cm−1 and bands with lower intensity at ∼1155 and 1007 cm−1 in treated plants were confirmed. According to PC1 (the first principal component) and PC2 (the second principal component), the highest intensity bands responsible for treatment differentiation in C. album could be assigned to chlorophyll, lignin, and carotenes. According to PC1 in A. theophrasti leaves the treatment differences could be observed 7 days after mesotrione treatment and PC2 gave a clear separation between all control and treated leaf samples. Raman spectroscopy may be a good complement to invasive analytical methods, in assessing the plant abiotic stress induced by bleaching herbicides.

AB  - Many vegetable crop plants, including tomato, have high water needs and one of the
options to overcome the negative effects of water reduction on yield is the use of deficit irrigation
methods. Detailed knowledge on the effects of different irrigation methods on fruit developmental
processes could be a critical factor in the analysis of the effect on final yield. It is well known that
water reduction limits the fruit growth rate and final fruit size in tomato, as a consequence of impact
on cell division and expansion processes. This paper reviews roles of cellular traits in the responses
of tomato fruit growth to deficit irrigation (DI) which were assessed using the wild-type (WT) and its
flacca mutant deficient in plant hormone abscisic acid (ABA). We specifically addressed how the cell
number, cell size and setup of pericarp cell layers were affected by water deficit during development.
Fruits of flacca in optimal irrigation are smaller as a consequence of smaller-sized cells in the pericarp.
DI induced a stronger negative effect on cell division and expansion in flacca than in WT at an early
stage. However, the effects of DI were similar in flacca and WT in ripe fruits. The main difference
between flacca and WT responses to water restriction was a stronger negative impact during the early
cell division in flacca, which is consistent with the involvement of ABA in the cell division process
and water stress-induced ABA synthesis in WT.

AB  - The aim of this study was to investigate the quinoa fruit and seed microstructure, as well as to determine the qualitative composition of quinoa whole seed spatial localisation of food reserves in cultivars Puno and Titicaca using two complementary spectroscopic techniques (Fourier Transform infrared and Raman). The analyses of the seeds also included measurements of the crude proteins and starch contents. The experiment was carried out during the 2016 growing season in rain-fed conditions in the north of Serbia. The analysis of the scores of the principal components based on the Raman spectra revealed two groups in both seed parts (cotyledons and perisperm). The analysis of the loadings highlighted the spectrum region that contributed to the differentiation, e.g. the band at 472 cm(-1) was related to the amylopectin content in the perisperm region. As for the cotyledons, the spectral range from 1100 to 1650 cm(-1) was responsible for genotype differences and it included both the most important bands derived from Amide I, II and quinoa protein with globoid crystals composed of phytin. IR analysis, similar to the analyses of the crude proteins and starch contents in the seeds, failed to reveal any differences in biochemical composition between two analyzed genotypes.
