Hemicellulose content is negatively regulated by soil water deficit. The effect of drought stress (25% WHC, water deficit conditions) on the absorbance of hemicelluloses in the flower abscission zone (AZ) of yellow lupine was analyzed. Control AZ fragments were collected from plants growing in the soil of optimal conditions (70% WHC). For analysis, sections of AZs were harvested on the 48th day of cultivation. Data are presented as averages ± SE (n = 3). Significant differences in the stressed plants in comparison to control plants are ^a p < 0.05 (Student’s t-test).
