A three-year-old plant of poplar and Tamarix gallica consumes ______ liters and ____ liters of water per day, respectively under optimum supply conditions:
Show answer Hide answer
Answer: A. 45,60
Explanation
Under optimum supply conditions, specific daily water consumption rates for three-year-old poplar and Tamarix gallica are documented. Poplar plants consume approximately forty-five liters of water per day under these well-watered plantation growth conditions. Tamarix gallica shrubs require around sixty liters of water daily due to their specific physiological transpiration demands. Plant water consumption depends heavily on ambient temperature, humidity, root system depth, and overall canopy leaf area. Fast-growing tree species like poplars typically exhibit high transpiration rates to support rapid structural biomass accumulation. Tamarix species are known halophytes and heavy water consumers often found thriving near desert water table margins.
Alternative numeric pairings fail to match established botanical research measurements for these specific three-year-old tree species. Option B suggests higher poplar consumption and higher tamarisk usage which contradicts established forestry irrigation study data. Option C overestimates the water requirements for young poplar specimens while underestimating mature shrub transpiration rates.
