With fruit that is barrel-shaped, the fruit itself is yellowish-orange in color and has white pulp. Updates? After the fruit has been conveyed away, the workers go through the field to collect the crowns (where they have been left on the tops of the plants) and place them on the conveyors for a trip to the bins which are then fork lifted and the crowns dumped into a planting machine. Retting time has been reduced from 5 days to 26 hours. The latter is a problem in other parts of tropical America also and in Trinidad. The palmetto beetle (Rhynchophorus cruentatus), which feeds on palm logs, enters the bud and lays eggs in young fruits and the fruit stalk. There is a great saving in harvesting costs because it reduces the need for successive pickings. These pineapples are free from spikes with a gold-yellow inside and orange exterior, as well as a spike-free leaf that is dark-green in color. For It, I've Not Been. For the fresh fruit market, a short section of stem is customarily left on to protect the base of the fruit from bruising during shipment. The stem continues to grow and acquires at its apex a compact tuft of stiff, short leaves called the "crown" or "top". A commercial industry took form in 1924 and a modern canning plant was erected about 1946.

It is marketed fresh only. Among several strains of 'Sugarloaf' are 'Papelon', and 'Black Jamaica', and probably also 'Montufar' ('Sugar Slice' of Guatemala). 'MacGregor', a variant of 'Nasal Queen' selected in South Africa and grown also in Queensland, is a spreading, more vigorous plant with broad leaves and large suckers produced less freely. The fruit is red or purple externally, cylindrical with square ends, shallow eyes, deep-yellow flesh, very slender core but has slips around the crown and too many basal slips to suit modern commercial requirements. The 'Red Spanish' reaches shipping-green stage (one week before coloring begins) in Puerto Rico 150 days after natural blooming. If you want a type of pineapple for your shish-kabobs, pineapple chunks are perfect because they are large enough and firm enough to fit onto the skewers without making them too mushy. In Queensland, tops and slips from the summer crop of 'Smooth Cayenne' are stored upside down, close together, in semi-shade, for planting in the fall. The plant is entirely smooth with no spine at the leaftip. Why don't libraries smell like bookstores? It can be used in various applications like artificial fibres, as a sound absorber and thermal insulator, and so forth. At 44.6-46.4°F (7-8°C) and above, 80-90% relative humidity and adequate air circulation, normal ripening progresses during and after storage. The pineapple plant has a short stout stem and a rosette of sword-shaped leaves with needle-like tips. Following harvest, these plants are cut close to the ground, the leaves are stripped off and the stems—usually 1 to 2 ft (30-60 cm) long and 3 to 4 in (7.5-10 cm) thick—are sliced lengthwise into 4 triangular strips. Black speck and water blister are mentioned among other problems of the pineapple. In this expertmeet, 13,403 plants/acre (32,167/ha) produced 9,882 fruits/acre (23,717/ha), weighing 31.28 tons/acre (75 tons/ha). The fruit is more or less conical, sometimes round; not colorful; weighs 1 1/2 to 3 lbs (0.68-1.36 kg). 'Monte Lirio', of Mexico and Central America, also has smooth leaves with no terminal spine. To a lesser degree, some growers have used "stumps", that is, mother plant suckers that have already fruited. Why is melted paraffin was allowed to drop a certain height and not just rub over the skin? With leaves that are reddish-green in color and brown spots, the Ripley pineapple has round-oval fruit that is dark-green in color, but pale-copper when it ripens fully. Fumigation of the soil contributes to high quality and high yields. With long leaves that are dark-green in color and reddish spots, this type of pineapple has a cylindrical shape and white fruit, with an inside that is orange in color. *Analyses of ripe pineapple made in Central America. Bromelain: The proteolytic enzyme, bromelain, or bromelin, was formerly derived from pineapple juice; now it is gained from the mature plant stems salvaged when fields are being cleared. It has a very small amount of fiber and fruit that is very succulent and sweet. The harvested fruits must be protected from rain and dew. When creating its fruit, it usually produces up to 200 flowers, although some large-fruited cultivars can exceed this. The fruit is sweeter yet with more acidity than 'Red Spanish', less fibrous and good for marketing fresh and for canned juice. By 1900, shipments reached a half million cases. Rabbits in winter eat the leaves as high as they can reach. The core is large and its extraction results in too large a hole in canned slices. Cameroun's annual production is about 6,000 tons. These are very vigorous plants that have a lot of spikes along the borders.
