Figure Lengend Snippet: Correlation between agronomic and physiological parameters in barley. GY, grain yield; TDW, total plant dry weight; HI, harvest index; PH, plant height; StN, stem number; SpN, spike number; StDW, stem dry weight; SpDW, spike dry weight; NDVI1, greenseeker reading 1; NDVI2, greenseeker reading 2; N, total nitrogen; δ 15 N, stable nitrogen isotope composition; C, total carbon; δ 13 C, stable carbon isotope composition; Chl, Chlorophyll; Flav, flavonoid; Anth, anthocyanin; NBI, Nitrogen Balance Index. Pearson correlation coefficient (r) is represented using a color gradient, where deep red corresponds to r=1, white indicates r=0, and deep blue represents r=-1.

Article Snippet: Normalized difference vegetation index , NDVI , Measured using leaves during grain filling with Hand Held optical sensor unit (GreenSeeker), 2002 NTech Industries, Inc., Ukiah, CA, USA). The instrument records the reflectance plot and the distance between the the GreenSeeker and canopy of the plant was kept constant at around 50 cm itself and, and the plot was kept constant at around 50 cm..
