harvest date. Variation of fruit acidity and sweetness are associated with the clone used, fruit maturation, growing conditions, and season ( Bartholomew and Paull, 1986 ; Bartolome et al., 1995 ; Dorey et al., 2016 ; Py et al., 1987 ; Saradhuldhat and

Although fresh market apples comprise the majority of global apple ( Malus ×domestica ) production, cider apples have been of particular interest recently because their higher acidity and tannin content (a group of polyphenols with bitterness and

.S. fertilizer industry to quantify the potential of a fertilizer to change soil acidity or alkalinity. The reported PM value for an acidic fertilizer, in units of calcium carbonate equivalents (CCE) of acidity per unit weight of fertilizer, refers to the CCE

It is relatively easy to set the initial target pH of a root substrate by matching lime type and rate with the acidity of the substrate components. The challenge lies in maintaining this target pH throughout crop production. Factors that impact pH

Abstract

Acidity was measured on ripe and overripe samples of 16 cultivars of tomato (Lycopersicon esculentum Mill.) ‘Ace’ and ‘Garden State’ were the lowest in acidity. In some samples of ‘Garden State’, 25% of the individual ripe fruits exceeded pH 4.8. Overripe tomatoes, tomato tissue infected with Alternaria and anthracnose, and fruits obtained from dead vines were also abnormally high in pH.

Internal flavor is one of the most important factors affecting the commodity value of fruit, mainly involving TSS content and acidity ( Wei et al., 2021 ). However, fruit internal flavor can be uneven as a result of being affected by a series of

. Therefore, this study was designed to determine if chemical composition of ‘Frontenac’ fruit is influenced by light intensity within the canopy. In addition to soluble solids, pH, and titratable acidity, we measured total phenolic and flavonoid

Abstract

Summer water stress in grapefruit (Citrus paradisi Macf.) trees caused high titratable acidity levels during the winter. The after effect of water stress lasted up to 6 months. Brief sudden rises in acidity during the winter were correlated with short durations of relatively high day temperatures. Such episodes did not affect the percentage total soluble solids.
