“…This finding aligns with the results obtained by Rezazad Bari et al (2021) who investigated 21 grapevine rootstocks under salinity conditions. They measured 19 parameters and employed chemometrics methods, including principal component analysis (PCA) and quadratic discriminant analysis (QDA), to determine the significant characteristics for distinguishing the rootstocks.…”

U TILIZING grape rootstocks is considered an efficient method to enhance the resistance against biotic and abiotic stresses. Therefore, a pot experiment was conducted during Two consecutive seasons 2020 and 2021.to evaluate the responses of 1-year-old rooted cuttings of commercially available grape rootstocks (SO4, Freedom, Ramsey, and Richter) planted in sandy soil, amended with compost; then irrigated with graduated levels of salt mixture solution (control, 1500, 3000, 4500, and 6000 ppm). The results obtained from biochemical and physiological measurements revealed that Ramsey rootstock outperformed the other rootstocks, significantly exhibiting the highest concentrations of nitrogen, potassium, magnesium, and proline in roots, while demonstrating the lowest sodium concentration in petioles. The results offer valuable insights on grape cultivation under salinity conditions with irrigation water concentration ranging from 1,500 to 3,000 ppm.

Different soybean varieties vary greatly in their nutritional value and composition. Screening for superior varieties is also essential for the development of the soybean seed industry. The objective of the paper was to analyze the feasibility of terahertz (THz) frequency-domain spectroscopy and chemometrics for soybean variety identification. Meanwhile, a grey wolf optimizer-support vector machine (GWO-SVM) soybean variety identification model was proposed. Firstly, the THz frequency-domain spectra of experimental samples (6 varieties, 270 in total) were collected. Principal component analysis (PCA) was used to analyze the THz spectra. After that, 203 samples from the calibration set were used to establish a soybean variety identification model. Finally, 67 samples from the test set were used for prediction validation. The experimental results demonstrated that THz frequency-domain spectroscopy combined with GWO-SVM could quickly and accurately identify soybean varieties. Compared with discriminant partial least squares (DPLS) and particles swarm optimization support vector machine, GWO-SVM combined with the second derivative could establish a better soybean variety identification model. The overall correct identification rate of its prediction set was 97.01%.

“…Fresh leaf samples were extracted with a 50 mM phosphate buffer solution containing 1 mM of EDTA and 1% (w/v) PVPP to evaluate the activity of superoxide dismutase (SOD) and catalase (CAT), as described by Rezazad Bari et al [35]. A spectrophotometric assay was performed according to Beyer and Fridovich [36] to determine SOD activity, which was expressed in units per mg of protein −1 .…”

Water and soil salinization significantly reduce crop yields. Among the strategies developed to counteract salt stress, biostimulants can maintain crop productivity, reversing its impact. In this context, there is interest in finding new substances that could act as biostimulants. Recently, the biostimulatory potential of Lemna minor L. (duckweed) extracts has been shown. This work aimed to highlight whether an extract from duckweed (Lemna extract—LE) could protect maize grown in salinity, exploring the mechanisms induced to improve crop resistance. Plants were grown by applying two concentrations of NaCl (150 and 300 mM), and some physiological, morphological, and biochemical traits were studied in control and salt-stressed samples, treated or not with LE. Salinity decreased shoots, roots, pigment, and soluble protein. LE prompted ameliorative changes at the root level and increased photosynthetic pigment and soluble protein. Furthermore, concerning the oxidative impairment provoked by salt stress, LE enhanced the cellular redox state, contrasting H2O2 and MDA accumulation and positively affecting the activity of superoxide dismutase (SOD—EC 1.15.1.1) and catalase (CAT—EC 1.11.1.6). The assessment of some mineral nutrients showed that LE stimulated their acquisition, especially for the highest salt dosage, explaining some benefits found for the parameters investigated.
