“…2). This is a confirmation of earlier results (Wilkinson and Perring 1961, Kohl 196'6, Lewis and Martin 1973, Ford and Quinlan 1979. The contents of nitrogen, potassium and magnesium were higher in the core than in the fruit flesh (Tab.…”

Apple trees (Malus pumila Mill. var. domestica Fuji/Malus prunifolia rootstock) showed a high susceptibility to bitter pit when supplyed with ammonium salt instead of nitrate (control) in the nutrient solution. When apple fruit was affected by bitter pit, a lower calcium as well as a higher nitrogen and ammonium‐nitrogen contents was observed in the fruit flesh near the calyx end. The activity of the mitochondrial Ca2+‐uptake of the fruit flesh near the calyx end was higher when the tree was grown with ammonium salt than when grown with nitrate. Both the activities of succinate: cytochrome c oxidoreductase and the mitochondrial Ca2+‐uptake per g of tissue were higher in affected fruit than in healthy fruit. Each of chlorpromazine, N‐(6‐aminohexyl)‐5‐chloro‐l‐napthalenesulfonamide (W‐7) and N‐(6‐aminohexyl)‐l‐naphthalenesulfonamide (W‐5), calmodulin antagonists, was infiltrated into the fruit for 20 min under reduced pressure (about 1 × 104 Pa). Few days later, numerous bitter pit‐like spots were observed in both fruit treated with W‐7 and chlorpromazine, while only a few spots were observed after the infiltration with W‐5, a less potent calmodulin antagonist. A possible mechanism for the occurrence of bitter pit is discussed.

“…Since these parthenocarpic "IAA" as well as "GA3 fruits" were smaller in size, a direct comparison with the control fruits was difficult, because normally there exists a negative correlation between fruit size and the Ca content (Wilkinson andPerring 1961, Bangerth andMostafawi 1969). 4-Chlorophenoxyacetic acid, a synthetic auxin, was therefore used, which in previous experiments induced high parthenocarpic fruit set with an almost normal fruit size.…”

A Role for Auxin and Auxin Transport Inhibitors on the Ca Content of Artificially Induced Parthenocarpic Fruits

Artificially induced parthenocarpic fruits of apples, pears and tomatoes, as well as seeded fruits treated with 2,3,5-triiodobenzoic acid, frequently show symptoms of Ca deficiency and a low Ca content. It was concluded that auxins, probably produced by the seeds, play a significant role in Ca translocation into fruits. Exogenous indoleacetic acid but not 4-chlorophenoxyacetic acid applications could replace the effect of seeds in this respect. Auxin transport, rather than auxin accumulation, seems to be necessary for Ca transport, as can be concluded from the effect of auxin transport inhibitors.

“…A wide variability in food composition has been reported for other foods, too. Indeed, even for foods grown on the self-same plant, up to 2.5-fold differences for some nutrients have been observed 32 . In contrast, the objective nutritional biomarkers used in this study take into account the diversity in the foods consumed and differences in bioavailability as they rely on the systemic presence of the respective compounds.…”

Biomarker-estimated flavan-3-ol intake is associated with lower blood pressure in cross-sectional analysis in EPIC Norfolk

Flavan-3-ols are a group of bioactive compounds that have been shown to improve vascular function in intervention studies. They are therefore of great interest for the development of dietary recommendation for the prevention of cardio-vascular diseases. However, there are currently no reliable data from observational studies, as the high variability in the flavan-3-ol content of food makes it difficult to estimate actual intake without nutritional biomarkers. In this study, we investigated cross-sectional associations between biomarker-estimated flavan-3-ol intake and blood pressure and other CVD risk markers, as well as longitudinal associations with CVD risk in 25,618 participants of the European Prospective Investigation into Cancer (EPIC) Norfolk cohort. High flavan-3-ol intake, achievable as part of an habitual diet, was associated with a significantly lower systolic blood pressure (− 1.9 (− 2.7; − 1.1) mmHg in men and − 2.5 (− 3.3; − 1.8) mmHg in women; lowest vs highest decile of biomarker), comparable to adherence to a Mediterranean Diet or moderate salt reduction. Subgroup analyses showed that hypertensive participants had stronger inverse association between flavan-3-ol biomarker and systolic blood pressure when compared to normotensive participants. Flavanol intake could therefore have a role in the maintenance of cardiovascular health on a population scale.
