Methods for Reducing Acidity in Citrus Fruit
PRO-GEN® (arsanilic acid or P-G) has been shown to reduce acidity of Florida grapefruit as effectively as lead arsenate. A series of experiments in the 1987-88 citrus fruit sea son reconfirmed that P-G was effective for this use with con centrations of 600-1500 ppm. P-G is water soluble. However, deliberate attempts to wash it off immediately following spray application reduced its effectivenes...
متن کاملSequential injection titration with spectrophotometric detection for the assay of acidity in fruit juices.
A simple sequential injection analysis (SIA) with spectrophotometric detection for an assay of acidity in fruit juice was investigated. An alkaline reagent (sodium hydroxide), a sample and an indicator (phenolphthalein) were first aspirated and stacked as adjacent zones in a holding coil. With flow reversal through a reaction coil to the detector, zone penetration occurred, leading to a neutral...
متن کاملDeveloping pineapple fruit has a small transcriptome dominated by metallothionein.
In a first step toward understanding the molecular basis of pineapple fruit development, a sequencing project was initiated to survey a range of expressed sequences from green unripe and yellow ripe fruit tissue. A highly abundant metallothionein transcript was identified during library construction, and was estimated to account for up to 50% of all EST library clones. Library clones with metal...
متن کاملPostharvest internal browning of pineapple fruit originates at the phloem.
A typical symptom of postharvest chilling injury (PCI) in pineapple fruit (Ananas comosus (L.) Merr.) is internal browning (IB) near the fruit core. Since vascular bundles (VBs) are localized to this region, it was hypothesized that the VBs might be the site of IB. To test this, the anatomy and histochemistry of VBs during chilling stress in four pineapple cultivars with different levels of sen...
متن کاملA Novel Method for Rapid Micropropagation of Pineapple
A novel micropropagation method for pineapple (Ananas comosus L.), based on shoot elongation induced in vitro, was demonstrated for two cultivars. Decapitated in vitro plantlets were used as explants. Shoot etiolation was induced by placing explants in a Murashige and Skoog (MS) medium containing NAA (10 μM) and incubating in darkness at 28C for 30 to 40 days. The mean number of the regenerated...
