Researchers have been using our tools to study dynamic drought stress responses in plants for decades.
In a recent study
comparing varieties of millet in China, the CI-203 Handheld Laser Leaf Area Meter
helped determine plant growth parameters.The hybrid variety of millet was found to exhibit higher drought resistance, with lesser reduction in net photosynthesis, and greater leaf area.
Another 2015 study
quantifies the effects of foliar spray on wheat in normal and drought stress conditions.The foliar spray contained selenium, an important plant micronutrient. In various measurements, including net photosynthesis with the CI-340 Handheld Photosynthesis System
, it was shown that supplemental selenium increased nutrient uptake, turgor and gas exchange, as well as overall wheat yield.
In an ecological study
from 2008, the CI-600 In-Situ Root Imager
and soil cores were used to examine the fine root production and mortality of Norway spruce in an experimental drought system. The results of the study concluded that mild periods of drought significantly increased fine root mortality, and this in turn increased soil organic matter as carbon from decaying roots is added to the soil.
