the aim of this study was to examine factors affecting adoption of mini-tuber seed potato. survey research design was used in this study. a sample of 100 potato growers who were informed about mini-tuber was selected and divided into adopter and non-adopter groups. questionnaire was used as the instrument for data collection and was validated by a panel of experts. a pilot study was conducted f...
Inclusion of cover crops in crop rotations has several benefits such as supplying nitrogen for the next crop. To investigate the effect of cover crops and different levels of nitrogen fertilizer on tuber yield, yield components, and different nitrogen efficiency indices of potato, a filed experiment was conducted as split plots arrangements in randomized complete block design with three replica...
Virus-free seed potatoes are generally divided into pre-elite seeds and certified seeds. To study the differences in dry matter accumulation distribution between through a field randomized block two-factor experiment, of four varieties were selected to explore growth characteristics two levels virus-free find way improve potato expansion efficiency. The results showed that process was slower pe...
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...
Truffles are hypogeous ectomycorrhizal (EM) fungi belonging to the genus Tuber. Although outplanting of truffle-inoculated host plants has enabled the realization of productive orchards, truffle cultivation is not yet standardized. Therefore, monitoring the distribution of fungal species in different truffle fields may help us to elucidate the factors that shape microbial communities and influe...
this study was conducted to evaluate different nutrient solutions effects on agria potato mini-tubers production under aeroponic system. the experiment was conducted in the laboratory and greenhouse of ardabil sabalan behparvar company in 2013. four recommended nutrient solutions including: lommen and struik (1992), kang and han (2005), otazu (2010) and hoagland and arnon (1950) were used in a ...
Genetic maps now can be constructed using thousands of genomewide single nucleotide polymorphisms (SNps) for identification of markers closely associated with agronomic traits. A diploid mapping population for potato (Solanum tuberosum L.) was developed from a pseudo-testcross between a homozygous line S. tuberosum Group phureja DM 1-3 516 r44 and a heterozygous outcrossing S. tuberosum Group T...
چکیده: در این تحقیق تأثیر ملاس که یکی از محصولات جانبی صنایع قند می باشد به عنوان یک افزودنی مقاومت خشک جدید در بهبود پالایش پذیری و ویژگی های فیزیکی و مکانیکی مقوای کنگره ای کهنه (occ) مورد بررسی قرار گرفته شد. بدین منظور پنج سطح ملاس( 0،5، 10، 15 و 18%) و سه سطح درجه روانی(420،400و320 میلی لیتر)به عنوان فاکتورهای متغیر در نظر گرفته شد و برای هر تیمار کاغذهای دست ساز با مساحت 2cm200 و وزن پای...
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...
