WebMulti-Pigment-Meter MPM-100 Chlorophyll Content Chlorophyll Content is a very sensitive test for nitrogen and sulfur plant stress, amongst many other types. For that reason, chlorophyll content measurement use is common for nitrogen fertilizer management. When test plant measurements drop to 90% of values from a well WebReduction or no-change in chlorophyll content of plant under drought stress has been observed in different plant species and its intensity depends on stress rate and duration. The chlorophyll content also decreases in drought stress. Low chlorophyll content is observed in harsh environment. Chlorophyll content might be considered as consistent
These are instruments that use light transmission through a leaf, at two wavelengths, to determine the greenness and thickness of leaves. Transmission in the infrared range provides a measurement related to leaf thickness, and a wavelength in the red light range is used to determine greenness. The ratio of the transmission of the two wavelengths provides a chlorophyll content index that is referred to as CCI or alternatively as a SPAD index. CCI is a linear scale, a… WebThe measurement of chlorophyll content can therefore yield important information relating to the presence of biotic stress factors and also of abiotic issues such as light, drought and pigment inhibiting herbicide …

But resistant cultivar to drought and thermal stress conditions had high chlorophyll content (Sairam et al, 1997). Other reports have represented that drought stress did not have effect on chlorophyll concentration
WebMar 18, 2024 · Under stress conditions, leaf chlorophyll content changes dramatically, which could provide insight into plant photosynthesis and drought resistance. Compared to traditional methods of evaluating chlorophyll content, hyperspectral imaging is more efficient and accurate and benefits from being a nondestructive technique.
