The potato tuber moth (Phthorimaea operculella Zeller) is the primary insect pest of cultivated potato (Solanum tuberosum L.) in tropical and subtropical regions, causing both foliar and tuber damage. In contrast, the Colorado potato beetle (Leptinotarsa decemlineata Say) is the most important insect pest in the northern potato production latitudes. The codon-modified Bacillus thuringiensis Bt-...
The occurrence of hypoxic conditions in plants not only represents a stress condition but is also associated with the normal development and growth of many organs, leading to adaptive changes in metabolism and growth to prevent internal anoxia. Internal oxygen concentrations decrease inside growing potato tubers, due to their active metabolism and increased resistance to gas diffusion as tubers...
One of the main obstacles in providing quality potato seed tubers is long dormancy period seeds. A study that explores this has been carried out to elucidate response release and initiation sprouts differences tuber weight storage duration before immersion cytokinin (6-benzylaminopurine). The was conducted at warehouse UPT Horticulture Parent Seed Kutagadung Berastagi, Department Food North Sum...
In the present study effects of production history on tuber sprout, root, stem development and crop yield of seed potato cultivars Fambo and Van Gogh were investigated in the High Grade Area of Finland (64.9 N, 25.4 E). The haulms of seed potatoes were destroyed at the time of flowering (50 days after planting, DAP), three weeks after flowering (75 DAP) and as a control the haulm was left to na...
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...
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....
A two-step method was developed to evaluate potato resistance to black scurf caused by Rhizoctonia solani. Tuber piece inoculum was first conducted in the laboratory, which was also first reported in this study. After inoculation with pathogen discs and culture for 48 h, the necrotic spots on the inoculated potato pieces were generated and measured by the crossing method. Further evaluation was...
