INTERNAL PHLOEM IN MYRISTICA

Postharvest 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...

Internal phloem in an interspecific hybrid of cassava, an indicator of breeding value for drought resistance.

We examined the stem anatomy of Manihot esculenta Crantz and its hybrid with M. oligantha Pax. Cross-sections were stained with safranin-alcian blue. Manihot esculenta and its hybrid were found to have the same vascular structure in bicollateral bundles with internal phloem, which has been associated with drought resistance in other plant groups. If this association is established for cassava, ...

Phytochemical Studies on Myristica fragrance Essential Oil

In the present study of phytochemical screening of the seed extract of Myristica fragrance essential oil using standard method of photochemical analysis. The solvents used for extraction of essential oil were methanol, dichloromethane, hexane and chloroform. The preliminary phytochemical investigation showed that Myristica fragrance essential oil to contain some secondary metabolites such as of...

Phloem transport in trees.

Phloem is like an enigmatic central banker: we know how important phloem is to plant function, but very little about how phloem functions as part of a whole-plant economy. Phloem transports carbohydrates, produced by photosynthesis and hydrolysis of reserve compounds, to sink tissues for growth, respiration and storage. At photosynthetic tissues, carbohydrates are loaded into phloem (Rennie and...
