- ... Flavonoids accumulate in tomato (Solanum lycopersicum L.) fruit cuticles during ripening. Their quantitative contribution to the biomechanical properties of the cuticle is studied in six tomato genotypes which show presence or absence of these compounds at the red ripe stage of fruit development. Tomato cuticles with flavonoids at red ripe showed a dramatic increase of these compounds between matu ...

- ... We only have a limited understanding of the nutrient uptake physiology of individual roots as they age. Despite this shortcoming, the importance of nutrient uptake processes to our understanding of plant nutrition and nutrient cycling cannot be underestimated. In this study, we used a ¹⁵N depletion method that allowed for the measurement of nitrate-N uptake rates on intact, individual, fine roots ...
