In order to detect the reaction of different potato genotypes to different irrigation regimes and evaluate their water productivity, a research was carried out as a split plot experiment based on a randomized complete block design with three replications in Agricultural Research Center and Natural Resources of Ardabil, Iran in 2015-2016. Five potato genotypes (Agria, Caesar, Savalan, 397081-1 a...
To evaluate the effect of herbicide band application and cultivator on weed control, yield and yield components of potato, an experiment was conducted using factorial arrangement based on randomized complete block design (RCBD) with four replications at Research Field of Ferdowsi University of Mashhad, Mashhad, Iran during 2015. Experimental factors included cultivator at two levels (with and w...
A novel potato micro-tuber-inducing compound was isolated from the culture broth of Lasiodiplodia theobromae Shimokita 2. The structure of the isolated compound was determined as (3R,6S)-6-hydroxylasiodiplodin by means of spectroscopic analyses, the modified Mosher method, and chemical conversion. The compound showed potato micro-tuber-inducing activity at a concentration of 10(-4) M, using the...
SNPs in genes functional in starch-sugar interconversion associate with natural variation of tuber starch 1 and sugar content of potato (Solanum tuberosum L). 2 L. Schreiber , A. C. Nader-Nieto , E. M. Schönhals, B. Walkemeier, C. Gebhardt 3 Max Planck Institute for Plant Breeding Research, Department of Plant Breeding and Genetics, 50829 Cologne, Germany 4 *The two first authors equally contri...
A ®eld lysimeter study was conducted to investigate the effect of initial soil salinity and salinity level of brackish subirrigation water on tuber weight and tuber size of three potato (Solanum tuberosum L.) cultivars (Kennebec, Norland and Russet Burbank) under simulated arid conditions. Both saline and non-saline initial soil conditions were simulated in a total of 36 lysimeters. Eighteen ly...
Starch and sugar content of potato tubers are quantitative traits, which are models for the candidate gene approach for identifying the molecular basis of quantitative trait loci (QTL) in noninbred plants. Starch and sugar content are also important for the quality of processed products such as potato chips and French fries. A high content of the reducing sugars glucose and fructose results in ...
The length of potato tuber dormancy depends on both the genotype and the environmental conditions during growth and storage. Abscisic acid (ABA) has been shown to play a critical role in tuber dormancy control but the mechanisms regulating ABA content during dormancy, as well as the sites of ABA synthesis, and catabolism are unknown. Recently, a temporal correlation between changes in ABA conte...
The potato tuber (Solanum tuberosum L.) ADP-glucose pyrophosphorylase activity is activated by a incubation with ADP-glucose and dithiothreitol or by ATP, glucose- 1-phosphate, Ca2+, and dithiothreitol. The activation was accompanied by the appearance of new sulfhydryl groups as determined with 5, 5'-dithiobis(2-nitrobenzoic acid). By analyzing the activated and nonactivated enzymes on SDS-poly...
The aim of this study was to evaluate the quality characteristics of seven yacon (Smallanthus sonchifolius Poepp. and Endl.) cultivars (Cajamarca, Cusco, Early White, Late Red, Morado, New Zealand and Quinault) cultivated in the southwest of Germany. The following phyto/chemical traits were investigated in different yacon tuber parts (flesh, peel, and whole tubers): total dry matter, sugar cont...
