    Testing of a biopreparation based on Bacillus amyloliquefaciens for winter wheat protection against diseases [Articol]
    (2025) Scerbacova, Tatiana; Curiev, Loredana; Stingaci, Aurelia; Gore, Andrei
    The results of the testing of the biological fungicide based on the bacteria Bacillus amyloliquefaciens, strain FZB24 to protect the winter wheat variety Moldova-614 from the complex of pathogens in the conditions of the Republic of Moldova. The research was carried out on the experimental field of the IGFPP of SUM. Two preparation consumption norms were tested: 2 kg/ha and 2,5 kg/ha. Used once by the spraying method. As a result, the biological efficiency against Blumeria graminis was 89,0% and 94,7%, Septoria tritici – 85,0% and 91,7%, respectively, Puccinia reconditа – 94,7% and 94.9%. Reduced development of other wheat diseases may be possible.

    Oil content in seeds by NMR relaxation method [Articol]
    (Editura USM, 2025) Harciuc, Oleg; Sütyemiez, Mehmet; Chistol, Marcela; Malii, Aliona; Stingaci, Aurelia
    The aim of our work was to evaluate the capability of NMR-relaxation method of the determination of oil content in walnut kernels and soybean seeds. NMR-relaxation spin-echoes for protons of the studied seeds were studied on a modernized NMR-relaxometer, using a sequence of 90°- and 180°- high-frequency pulses, with an interval 3.5 ms. As standards in NMR calibration for walnut kernels and for soybean seeds were used different oils. The oil content of commercial walnut kernels SRL “Monicol” is 69±1%, which corresponds to the typical range for the crop, 64- 72%. After harvest 2021 the minimal oil content was in the seeds of soybean variety Pentata (14,6±0,2% for the seeds with dry weight 100-150 mg and 14,9±0,4% for the seeds with dry weight 200-250 mg) and the maximal oil content was in seeds of soybean variety Ladutsa (19,3±0,3% for the seeds with dry weight 100-150 mg and 19,7±0,5% for the seeds with dry weight 150-200 mg).
