WebChlorophyll fluorescence emitted from plant leaves gives an insight into the health of the photosynthetic systems within the leaf. Chlorophyll fluorometers are designed to measure variable fluorescence of photosystem II. This variable fluorescence can be used to measure the level of plant stress. WebSince leaf chloroplasts contain about 70% of the leaf nitrogen (N), the leaf chlorophyll and N contents are closely correlated (Wood et al., 1992). Since plant growth reflects the total N supply from all sources, the plant N status can be considered as an indicator of the soil N availability (Varinderpal-Singh et al., 2010). Web1 mrt. 2016 · Leaf chlorophyll content was directly measured. From the section of the leaf used for spectral measurements, a 10.1-mm-diameter disk ( Fig. 1) was collected and placed in 3.5 mL of dimethyl sulfoxide (DMSO) to extract leaf pigments for 48 h in the dark ( Hiscox and Israelstam, 1979; Barnes et al., 1992 ). sahdra bus service
