Název v původním jazyce

The poplar clone (populus Maximowiczii A. Henry × P. Nigra L.) growth under the controlled environment of growth chambers

Popis výsledku v původním jazyce

The objective of this study is to test the clone J-105 (Populus maximowiczii A. Henry × Populus nigra L.) responses to high temperatures under different water supply, CO2 and VPD levels. The experiment was established in May, 2014 by 144 cuttings planted into the pots. Sixty pots were placed into 5 growth chambers in July with the number of 12 pots per 1 chamber. The pots were split into 2 variants per 1 chamber – wet and dry treatment. The measurements, consisted in measurements of the plant heights, soil moisture (using ThetaProbe Soil Moisture Sensor) and CO2 response curves (using LI-6400 Portable Photosynthesis System), were carried out weekly. There were 4 parameters set up within each chamber under 2 protocols: (1) daily temperature course, (2) relative humidity (Rh) that together with temperature enable to control VPD values, (3) CO2 values and (4) PAR. The protocol for the control group was also established. The randomization between chambers was carried out weekly. The initial hypothesis was based on the assumption that elevated CO2 concentration (EC) will improve the water use efficiency and thus reduce the negative impact of drought, while increased air temperature and higher VPD will, on the contrary, amplify the negative effects of drought.
