Observation Pericarp had a lower light-harvesting to active-centre chlorophyll proportion than locular parenchyma.
Observation In Yellow Pear the upper calyx surface had ETR of 154 µmol m−2 s−1.
Observation In Yellow Pear the lower calyx surface had ETR of 88 µmol m−2 s−1.
Observation Green shoulder ETR was 203 µmol m−2 s−1.
Observation Distal pericarp ETR was 97 µmol m−2 s−1.
Observation Locular parenchyma ETR was 66 µmol m−2 s−1.
Association Lower ETR tissues diverted absorbed energy more rapidly to non-photochemical pathways.
Observation Locular parenchyma had much lower qP than pericarp at equivalent PFD.
Observation Locular parenchyma and pericarp had similar qN levels.

Intervention effect Dry matter and sugar content of tomato fruit were higher under high EC than under 2 dS/m.
Observation Total dry matter yield of tomato was the same across treatments except the high EC, high transpiration treatment.
Observation In the high EC, high transpiration treatment, blossom-end rot reduced marketable tomato dry matter by 25 percent.
Observation Tomato fruit elasticity was not affected by any treatment once size differences were accounted for.
