The hardware design of tuber electrical resistance tomography (TERT) system is one of the key research problems of TERT data acquisition system. The TERT system can be applied to the tuber growth process monitoring in agriculture, i.e., the TERT data acquisition system can realize the real imaging of tuber plants in soil. In TERT system, the imaging tuber and soil multiphase medium is quite com...

Eighteen hybrid onion and 23 open-pollinated (OP) varieties were tested in southern New Mexico for plant characteristics, disease resistance, and bulb yield in order to determine if hybrid varieties outperformed OP varieties. Varieties were shortto intermediate-day in their bulbing response and were planted in the fall seasons of 1997 and 1998 and harvested the following May or June. Varieties ...

Thirty-nine commercial varieties of head cabbage were evaluated for feeding preference of the diamondback moth (DBM), Plutella xylostella, at Kula, Hawaii, USA. Varieties were evaluated for density of caterpillars, extent of feeding damage and percentage of marketable heads. Twelve out of 39 (31%) varieties that showed the least DBM caterpillar damage and produced high percentage of marketable ...

Abstract The technology of hybrid breeding in diploid potatoes creates opportunities to design novel and improved cultivation systems based on true potato seeds. A promising pathway produce seed or ware tubers is by transplanting greenhouse-raised seedlings into the field. This study explored effects date seedling age tuber yield, using seedlings. Field trials with experimental genotypes were c...

given the importance of potato in the economy and people’s nutrition, as well as planting of disease-free seeds, it seems necessary to produce healthy seeds through tissue culture. this study was conducted during 2012-2013 at the research center of agricultural university of tajikistan aiming to evaluate the effect of different sizes of mini-tuber on yield and yield components of potato crop. a...

this experiment was conducted in andimeshk region (north of khouzestan) to study the effects of nitrogen levels on plant characters of  two potato cultivars (solanum tuberosum l.) in identical conditions of poultry manure, in 2012-2013 crop year, as a factorial randmaized complete block design with three replications. the first factor was consisting of four nitrogen levels (0, 70,140 and 210 kg...

The study presents results of a three-year experiment variability different potato varieties in Montenegro: early maturity (Riviera), medium (Almera, Aladin and Bounty) late (Agria, Margarita, Kennebec Desiree). research was conducted during 2015, 2016 2017, acid, brown soil three climatic locations: Nedakusi (556 m a.s.l.), Sutivan (680 a.s.l.) Orahovica (900 a.s.l.). Field experiments were se...

Fructokinase (FRK) proteins play important roles in catalyzing fructose phosphorylation and participate in the carbohydrate metabolism of storage organs in plants. To investigate the roles of FRKs in cassava tuber root development, seven FRK genes (MeFRK1-7) were identified, and MeFRK1-6 were isolated. Phylogenetic analysis revealed that the MeFRK family genes can be divided into α (MeFRK1, 2, ...

A field experiment was conducted to assess the effect of farmyard (cattle) manure (FYM) and inorganic nitrogen (N) phosphorus (P) fertilizers on growth and tuber yield of potato (Solanum tuberosum L.). The treatments consisted of factorial combination of 4 levels of FYM (0. 10, 20 and 30 t h-1) and three levels of inorganic NP fertilizers (0, 33.3%, 66.6% recommended rates) laid out in a Random...

Anthocyanin content of potato tubers is a trait that is attracting increasing attention as the potential nutritional benefits of this class of compound become apparent. However, our understanding of potato tuber anthocyanin accumulation is not complete. The aim of this study was to use a potato microarray to investigate gene expression patterns associated with the accumulation of purple tuber a...
