INTRODUCTION OF DAURIAN RHODODENDRON (RHODODENDRON DAURICUM L.) AND DIKUSHA CURRANT (RIBES DIKUSCHA FISCH.) FROM EASTERN YAKUTIA INTO WESTERN YAKUTIA // Научно-методический электронный журнал «Концепт». – 2026. – . – URL: http://e-koncept.ru/2026/0.htm
The article presents the results of introduction experiments with two rare shrub species, Rhododendron dauricum and Ribes dikuscha, under the sharply continental climate of Yakutia. A key variable in the study was the comparison between the native habitat conditions (Maysky District: January mean −42°C, July mean +15°C, mountainous terrain) and the introduction site (Suntar District: January mean −33…−35°C, July mean +17…+19°C, plateau relief). Over three growing seasons (2022–2024), Rhododendron dauricum demonstrated a highly successful introduction outcome, showing stable annual development, increased flowering duration (from 8 to 15 days), a total height increment of 22 cm (from 24 cm to 46 cm), and leaf dimensions approaching natural values. The plant exhibited high frost hardiness, retained its natural growth habit, and showed no signs of pest or disease damage. Ribes dikuscha displayed satisfactory vegetative adaptation but failed to achieve generative development (no flowering or fruiting) during the five-year observation period, despite strong frost resistance and disease tolerance.
