In the past, only about 10% of the World population used root crops as the major staple, [1] but presently the diet of most Ghanaians is based on roots and tubers, and on processed cereal grains. The common roots and tubers utilized in Ghana are mostly cassava, yam and cocoyam. Cereals such as rice, maize and sorghum are also greatly patronized. However, there are other important roots and tube...

BACKGROUND AND AIMS The control of dormancy in yam (Disocorea spp.) tubers is poorly understood and attempts to shorten the long dormant period (i.e. cause tubers to sprout or germinate much earlier) have been unsuccessful. The aim of this study was to identify and define the phases of dormancy in Dioscorea rotundata tubers, and to produce a framework within which dormancy can be more effective...

The incidence and outcome of epilepsy in tuberous sclerosis (TS) patients have not yet been thoroughly investigated. The aim of this study was to evaluate the clinical features and prognosis of epileptic seizures associated with TS. The medical records of 29 patients who satisfied the diagnostic criteria for TS and were followed up for at least 2 years at the Department of Pediatrics, Chonnam N...

Separating clods from potato tubers is one of the most challenging jobs in a potato harvester. Discriminating between potato tubers and clods is the first step in developing an automatic separation system on potato harvesters. In this study, an acoustic-based intelligent system was developed for high speed discriminating between potato tubers and clods. About 500 kg mixture of potato tubers and...

According to the Chinese Pharmacopoeia 2015, only processed Aconitum tubers can be clinically applied, and the effect of processing is unclear. This research aimed to explore the effect of processing on cardiac efficacy of alkaloids in Aconitum tubers. First, the chemical ingredients in unprocessed and processed Aconitum tubers were identified and compared by using high performance liquid chrom...

Chepang, inhabiting the rugged terrain of Mahabharat and Churia range in central Nepal, is a group of indigenous people suffering from severe food insecurity. Their ancestors lived a semi-nomadic life up to one and half century back. To a large extent, Chepang still continue their traditional way of living, which includes collection of wild tubers (‘kandamul’), hunting and fishing. Chepangs are...

Transcriptional and allosteric regulation of ADP-Glc pyrophosphorylase (AGPase) plays a major role in the regulation of starch synthesis. Analysis of the response after detachment of growing potato tubers from the mother plant revealed that this concept requires extension. Starch synthesis was inhibited within 24 h of tuber detachment, even though the catalytic subunit of AGPase (AGPB) and over...

'Nagasaki Kogane' is a new potato variety bred from a cross between 'Saikai 35' as a female parent and 'Saikai 33' as a male. 'Saikai 35' is resistant to bacterial wilt, contains the H1 and Rychc genes for resistance to the potato cyst nematode (PCN) and potato virus Y (PVY), respectively, and has high carotenoid content, while 'Saikai 33' has large and high-yielding tubers and is resistant to ...

Alexandre E.M.C., Rodrigues I.M., Saraiva J.A. (2015): Influence of thermal and pressure treatments on inhibition of potato tubers sprouting. Czech J. Food Sci., 33: 524–530. The effect of short duration thermal treatments (60 and 65°C for 1 min) and low intensity high pressure treatments (15 and 30 MPa for 10 min) on the sprouting of potato tubers was applied individually and sequentially, as ...

Zhejiang and Sichuan are regarded as two genuine producing areas of Ophiopogonis radix in China. To study the difference in the quality of Ophiopogonis radix from these two places, the contents of three reported bioactive saponins, that is, ophiopogonins B, D, and D', in tubers and fibrous roots of Ophiopogon japonicus from Cixi city of Zhejiang and Santai county of Sichuan were quantified usin...
