Выявлено, что интенсивность поглощения углекислого газа и скорость прироста фитомассы A. japonica начинают снижаться при влажности почвы ниже 60% от наименьшей влагоёмкости почвы (НВ). Максимальное значение интенсивности поглощения СО2 листьями A. japonica при оптимальной влагообеспеченности составило 0,95 мг/(см2х сутки). При влажности почвы 15% HB интенсивность поглощения СО2 снизилась до 20% от максимального значения поглощения ССЬ, а скорость прироста биомассы листьев уменьшилась в 25 раз. Максимальное среднемесячное количество поглощенного СО2 в период активной вегетации растения A. japonica зафиксировано в мае и составило 0,83 мг/(см2х сутки), а максимальная среднемесячная скорость прироста объема фитомассы листьев (0,36 см3/сутки) отмечена в августе. Фаза наиболее активного роста фитомассы A. japonica приходится на август. Повысить скорость прироста фитомассы в августе можно путем снижения температуры воздуха, а также увеличения относительной влажности воздуха посредством капельного орошения.</p></abstract><trans-abstract xml:lang="en"><p>The aim of the study was to determine the effect of insufficient moisture supply on the absorption of carbon dioxide by Aucuba japonica Thunb., as well as the dynamics of the growth of phytomass and the amount of CO2 absorbed by A. japonica at optimal moisture supply during the active growing season from May to September on the Southern coast of the Crimea, a region of dry subtropics. It was revealed that the carbon dioxide absorption rate and the growth rate of A. japonica phytomass begin to decrease when the soil moisture was below 60% of field capacity (FC). The maximum value of CO2 absorption intensity by A. japonica leaves at optimal soil water supply was 0.95 mg/(cm2 x day). At a soil water content of 15% FC, the CO2 absorption rate decreased to 20% of the maximum CO2 absorption value, and the leaf biomass growth rate decreased by 25 times. The maximum monthly average amount of absorbed CO2 during the period of active vegetation of the A. japonica plant was recorded in May and amounted to 0.83 mg/(cm2 x day), and the maximum monthly average rate of increase in the volume of leaf phytomass (0.36 cm3/day) was noted in August. The phase of the most active growth of A. japonica phytomass occurs in August. It is possible to increase the growth rate of phytomass in August by lowering the air temperature, as well as increasing the relative humidity through drip irrigation.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>аукуба японская</kwd><kwd>фотосинтез</kwd><kwd>освещенность</kwd><kwd>засухоустойчивость</kwd><kwd>влажность почвы</kwd><kwd>прирост фитомассы</kwd><kwd>фитомониторинг</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Japanese aucuba</kwd><kwd>photosynthesis</kwd><kwd>luminosity</kwd><kwd>drought tolerance</kwd><kwd>soil moisture</kwd><kwd>growth of phytomass</kwd><kwd>phytomonitoring</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ильницкий О.А., Плугатарь Ю.В., Корсакова С.П.
