Columns with data corresponding to Fefertilized leaves are labeled “Fefertilized” in case in the treated (distal) leaf location and “Fefertilized” in case of your (basal) untreated region.In sugar beet, the foliar Fe therapy also led to increases within the concentration of photosynthetic pigments inside the distal treated leaf area (Table 4). The boost was largest inside the case of carotene, Chl b, and Chl a, (eight.8, six.four, and 6.0fold, respectively), and significantly less marked in the case of neoxanthin and lutein (four.eight and four.6fold, respectively). All pigment values identified inside the treated leaf areas soon after fertilization had been nevertheless reduced (in the variety 4476 ) than those identified in leaves of Fesufficient p.
