Seasonal variation (e.g. temperature and photoperiod) between growing seasons might affectinulin content and inulin yield of Jerusalem artichoke. However, there is limited information ongenotypic response to seasons for inulin content and inulin yield. The objective of this studywas to investigate the variability in genotypic response to seasons for inulin content and inulinyield of Jerusalem a...
The success of sustainable crop production depends on our ability to select or create varieties that can allocate resources to both growth and defence. However, breeding efforts have emphasized increases in yields but have partially neglected defence traits against pests. Estimating the costs of multiple defences against tuber herbivores and the tradeoffs among them, as well as understanding th...
BEL1-like transcription factors are ubiquitous in plants and interact with KNOTTED1 types to regulate numerous developmental processes. In potato (Solanum tuberosum subsp. andigena), the BEL1-like transcription factor StBEL5 and its Knox protein partner regulate tuber formation by targeting genes that control growth. RNA detection methods and heterografting experiments demonstrated that StBEL5 ...
Potato tuber is a high yielding food crop known for its high levels of starch accumulation but only negligible levels of triacylglycerol (TAG). In this study, we evaluated the potential for lipid production in potato tubers by simultaneously introducing three transgenes, including WRINKLED 1 (WRI1), DIACYLGLYCEROL ACYLTRANSFERASE 1 (DGAT1) and OLEOSIN under the transcriptional control of tuber-...
abstract: the potato tuberworm, phthorimaea operculella (zeller), is an important insect pest of potato (solanum tuberosum l.) in the storage and field in most parts of the world especially in tropical and subtropical regions due to its close relationship with the host, high reproductive potential and high economic losses. information on host preference, life table parameters and digestive en...
Potato tuber necrotic ringspot disease (PTNRD) is a tuber deformity associated with infection by the tuber necrotic strain of Potato virus Y (PVYNTN). PTNRD negatively impacts tuber quality and marketability, and poses a serious threat to seed and commercial potato production worldwide. PVYNTN symptoms differ in the cultivars Waneta and Pike: Waneta expresses severe PTNRD and foliar mosaic with...
The impacts of fosthiazate on potato (Solanum tuberosum) tuber yields and populations of root lesion nematodes (primarily Pratylenchus penetrans) were studied during 1991-1994 in experimental plots on Prince Edward Island. Tuber yields were greater in treated plots when compared to untreated plots by 8% and 30% during 1991 and 1993, respectively. Numbers of nematodes in roots were reduced by th...
Potato crop in Egypt occupies 20% of the total area devoted for vegetable plantations and any disturbance in its production affects severely its local and export impact. Brown rot disease on potato is the most cereous disease affecting potato exportation. Therefore, competing such disease is an obligate practice to control the pathogenic causal bacterium. Biological control became recently an e...
Global consciousness of food safety, health and environmental issues has stimulated interest in alternative agricultural systems like organic farming. Since information on organic farming of tuber crops is meagre, a field experiment was conducted in split plot design over a five-year period at Central Tuber Crops Research Institute, India. The aims were to evaluate the impact of organic, c...
Due to production importance and potato minituber sleep, this research was carried out as factorial based on randomized complete blocks design with three replications at the Research Greenhouse of Ferdowsi University of Mashhad, Iran, in 2013. Treatments included foliar application of growth regulators at two physiological growth stages (stolen initiation and tuber initiation) and growth regula...
