A nondestructive method for detection of translucency, a physiological disorder in pineapple, would be beneficial to the industry. Ninety-two pineapples were imaged with X-ray to determine whether translucency could be detected. After imaging, each pineapple was cut open to determine the true level of the disorder and rated on a scale from 1 (no translucency) to 5 (extremely translucent). The X...

The introduction of the elite pineapple variety, MD-2, has caused a significant market shift in the pineapple industry. Better productivity, overall increased in fruit quality and taste, resilience to chilled storage and resistance to internal browning are among the key advantages of the MD-2 as compared with its previous predecessor, the Smooth Cayenne. Here, we present the genome sequence of ...

Bioactive compounds and antioxidant capacities of “Phulae” and “Nanglae” pineapple (Ananas comosus L. Merr) which are important geographical indications of Chiang Rai, Thailand were investigated. Two pineapple varieties were collected at 20-40 % yellow peel colour. Total soluble solids (TSS), titratable acidity (TA), total polyphenols, β-carotene, vitamin C and antioxidant capacity (ferric redu...

Many newly set pineapple plants die from pineapple mite, Dolichotetranychus floridanus (Banks), infestations. Other infested plants remain small and produce very little or no fruit. Although this mite infests plants of all ages, it is a serious pest only on young ones. Nursery stock distributed or sold by nurserymen, or used by fruit producers, should be free of mites and other pests. Control o...

Circadian clock provides fitness advantage by coordinating internal metabolic and physiological processes to external cyclic environments. Core clock components exhibit daily rhythmic changes in gene expression, and the majority of them are transcription factors (TFs) and transcription coregulators (TCs). We annotated 1,398 TFs from 67 TF families and 80 TCs from 20 TC families in pineapple, an...

Effect of cover crops intercropped with pineapple (Ananas comosus) on Rotylenchulus reniformis population densities and activity of nematode-trapping fungi (NTF) were evaluated in two cycles of cover crop and pineapple. Sunn hemp (Crotalaria juncea), rapeseed (Brassica napus), African marigold (Tagetes erecta), or weeds were intercropped with pineapples. Beds planted with sunn hemp or rapeseed ...

A 59-year-old man was admitted to our department with epigastric pain and nausea. The patient mentioned that he had swallowed heated mastic to treat constipation shortly before his symptoms developed. He had no history of any diseases. His vital signs were within normal limits. The physical examination findings were normal, and the results of laboratory tests were unremarkable. Upper gastrointe...

Pineapple production in Costa Rica increased nearly 300-fold during the last 30 yr, and >40,000 hectares of land are currently dedicated to this crop. At the end of the pineapple cropping cycle, plants are chopped and residues incorporated into the soil in preparation for replanting. Associated with increased pineapple production has been a large increase in stable fly, Stomoxys calcitrans (L.)...

The first written record of pineapple in Hawaii is from 1813. In 1901 commercial pineapple production started, and in 1924 the Experiment Station for pineapple research was established. Nematode-related problems were recognized in the early 1900s by N. A. Cobb. From 1920 to approximately 1945 nematode management in Hawaiian pineapple was based on fallowing and crop rotation. During the 1920s an...

BACKGROUND Pineapple (Ananas comosus var. comosus), is an important tropical non-climacteric fruit with high commercial potential. Understanding the mechanism and processes underlying fruit ripening would enable scientists to enhance the improvement of quality traits such as, flavor, texture, appearance and fruit sweetness. Although, the pineapple is an important fruit, there is insufficient tr...
