The impact of aeration on potato (Solanum tuberosum L.) minituber production under soilless conditions
/min)] were compared, particularly on tuberization and growth characteristics. In both cultivars examined, increasing the level of aeration led to higher number of stolons and tubers. Agria was more responsive and consisted of more large tube rs rather...
Screening bactericidal effect of Pectobacterium carotovorum subsp. carotovorum strains against causal agent of potato soft rot
This study focuses on the potential of Pectobacterium carotovorum subsp. carotovorum (Pcc) strains
producing bacteriocin as a tool to control potato soft rot disease. Thirty out of 48 purified
bacterial strains ...
Taxonomic Revision of the Dioscorea campestris Species Assemblage (Dioscoreaceae)
Effects of drip irrigation regimes on potato tuber yield and quality
To evaluate the effects of drip irrigation regimes on potato (Solanum tuberosum
L.) tuber yield and quality, an experiment was conducted in 2009 and 2010.
Experimental factors were the irrigation regimes including: FI, providing 100...
Influence of weed competition on potato growth, production and radiation use efficiency
% tuber yield loss. The onset of the CPWC ranged from 486 to 572 GDD, at 5% and 10% yield loss level corresponding to 11 and 19 days after crop emergence, respectively. The end of the CPWC varied from 1372 to 1164 GDD, at 5% and 10% yield loss level...
Low sensitivity to photoperiod may increase potato yield in short day through the maintenance of sink and source balance
Photoperiod is one of the environmental factors which affect the tuberization of potatoes. In order to determine the effects of photoperiod on tuberization of two potato cultivars, the effects of long (14 hours) and short (8 hours) days...
Efficacy of entomopathogenic nematodes against potato tuber moth, Phthorimaea operculella (Lepidoptera: Gelechiidae) under laboratory conditions
The susceptibility of potato tuber moth, Phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae) to native and commercial strains of entomopathogenic nematodes (EPNs) was studied under laboratory conditions. Native strains of EPNs were collected...
Evaluation of Effect of Physiological Growth Indices of Potato (Solanum tuberosum L.) Cultivars in Farmian and Jolgeh- Rokh Regions
ارزیابی شاخص¬هاي رشدي ارقام سیب¬زمینی (Solanum tuberosum L.) در دو منطقه فریمان و جلگه رخ
اين مطالعه بهمنظور بررسی شاخصهاي فیزيولوژيکی (شامل شاخص سطح برگ (LAI)، سرعت رشد غده (TGR)، سرعت رشد محصول (CGR) مؤثر بر عملکرد دو رقم سیبزمینی (آگريا و فونتانه) در مراحل مختلف رشد گیاه از سبز شدن تا رسیدگی و همچنین ...
Effect of Nutritional Treatments on Physiological Characteristics and Tuberization of Potato Plants under Hydroponic Sand Culture
Under hydroponic condition, number and size of potato tubers are usually controlled by nutritional
factors such as nitrogen (N), phosphorus (P), and pH. The main objective of the present
study was to find an appropriate combination...
