![]() Correlations between fresh weight, chlorophyll, anthocyanin, nitrogen, phosphorus, and potassium content were substantially affected by selection of datasets used for analyses some relationships were revealed when analyzed separately by individual treatments, while others were more likely to be detected when analyzed by individual accessions. Phosphorus and nitrogen deprivation considerably increased anthocyanin content in red-colored accessions, but anthocyanin was decreased in dark green-colored accessions, indicating differences in regulation of anthocyanin biosynthesis. Nitrogen and phosphorus deprivations, however, extensively decreased fresh weight and affected plant composition. Potassium deprivation had no obvious effect on plant weight or composition, apart from substantially decreased potassium content. The control treatment provided optimal levels of macronutrients for plant growth, while other treatments deprived plants of either N, P, or K. ![]() ![]() ![]() Eight lettuce accessions were subjected to five fertilization treatments to investigate genetic differences in reaction to N, P, and K fertilization. Little is known, however, about response of baby leaf lettuce to nitrogen (N), phosphorus (P), and potassium (K) fertilization. Lettuce harvested at the baby leaf stage is a popular component of mixed salads in ready-to-use packages. ![]()
