ПЕРСПЕКТИВЫ ВВЕДЕНИЯ В КУЛЬТУРУ БРУСНИКИ ОБЫКНОВЕННОЙ (V. VITIS-IDAEA L.) В УСЛОВИЯХ МАГАДАНСКОЙ ОБЛАСТИ

Abstract

Vaccinium vitis-idaea L. - common lingonberry occupies a special place in nature due to the value of its food and medicinal and prophylactic properties. Work on domestication of lingonberry is very limited. In Russia, extensive research on lingonberry selection was carried out at the Kostroma Forest Experimental Station. The result of this work was 4 varieties of lingonberry. In the Magadan Region, the work on domestication of lingonberry is of a pioneering nature. The object of the study were samples of common lingonberry plants (Vaccinium vitis-idaea L.). The collection of material for the research was carried out in 2023 in the Priokhotsk zone of the Magadan region, in the Olsky district, during the phase of active fruiting of plants - in September. For the study, 17 samples of partial plants of common lingonberry were selected. Evaluation of the productivity components of the studied samples revealed a high degree of variability in the components of the yield. The strongest variability was observed in the number of shoots (CV = 43.5%). The average degree of variability was noted for the length of shoots (CV = 16.34%) and their foliage (CV = 15.22%), the indicators varied, respectively, within 6 - 10 cm and 9 - 19 leaves. According to the fractional division, 47% of the fruits of the selected samples correspond to the medium fraction, the rest - to the small one. The average fruit weight in the samples was highly variable (CV = 46.14%). The average fruit diameter, depending on the sample, could be either 5.6 mm or 11.2 mm (CV=18.97%). As a result of studying and analyzing the samples of common lingonberry, 7 specimens were identified that were of interest for further work. Based on the results of office observations, it was established that the lingonberry samples selected and placed in laboratory conditions showed low resistance to stressful situations and weak viability in unnatural conditions.
