Assuring Potato Tuber Quality during Storage: A Future Perspective
نویسندگان
چکیده
Potatoes represent an important staple food crop across the planet. Yet, to maintain tuber quality and extend availability, there is a necessity to store tubers for long periods often using industrial-scale facilities. In this context, preserving potato quality is pivotal for the seed, fresh and processing sectors. The industry has always innovated and invested in improved post-harvest storage. However, the pace of technological change has and will continue to increase. For instance, more stringent legislation and changing consumer attitudes have driven renewed interest in creating alternative or complementary post-harvest treatments to traditional chemically reliant sprout suppression and disease control. Herein, the current knowledge on biochemical factors governing dormancy, the use of chlorpropham (CIPC) as well as existing and chemical alternatives, and the effects of pre- and post-harvest factors to assure potato tuber quality is reviewed. Additionally, the role of genomics as a future approach to potato quality improvement is discussed. Critically, and through a more industry targeted research, a better mechanistic understanding of how the pre-harvest environment influences tuber quality and the factors which govern dormancy transition should lead to a paradigm shift in how sustainable storage can be achieved.

Potato Dormancy Regulation: Use of Essential Oils for Sprout Suppression in Potato Storage
Sprout suppression is essential in assuring potato quality. Release of natural tuber dormancy is affected by production as well as storage environmental factors, cultivars and tuber metabolic activities. Plant growth regulators are also shown to play important roles in regulating tuber dormancy. In commercial storage, sprouting is primarily controlled by low temperature combined with chemical i...

Abstract Obtaining high potato (Solanum tuberosum L.) tuber yield through increased number and weight of quality tubers is important for farmers while the quality factors are of interest for food processing industries. Potato processing industries require high quality tubers having the highest possible dry matter, starch and protein contents. A two-year field study was carried out as a factoria...

The relationships of potato (Solanum tuberosum L.) tuber membrane permeability and membrane lipid composition to sugar accumulation were examined. Tubers from four potato cultivars were stored for 40 weeks at 3 degrees C and 9 degrees C. Rates of tuber membrane electrolyte leakage, total fatty acid composition, free fatty acid composition, and sugar content were measured throughout the storage ...

‘SpuntaG2’ is a transgenic potato (Solanum tuberosum) cultivar that contains the cry1Ia1 gene for resistance to potato tuber moth (Phthorimaea operculella), which is a serious pest of potato in many parts of the world. Previous studies have characterized ‘SpuntaG2’ at the molecular level and evaluated it for safety as a human food source. The objective here was to determine the efficacy of ‘Spu...
