in this research, the effect of crops such as corn, wheat, sugar beet and clover as previous crop on incidence of leaf and crown wart disease of sugar beet was studied. in the first year, corn, wheat, clover and sugar beet were planted as previous crop in a randomized complete block design with four replications. the amounts of turnover of nitrogen to the soil due to crop residue and their effe...

beet necrotic yellow vein virus (bnyvv) is the causal agent of sugar beet rhizomania, disease .  in the present study which was conducted in 2005 in shiraz, iran, serological methods (including elisa) were used for detection of disease and screening of disease tolerant germplasm in sugar beet breeding programs. for doing this, iranian isolate of bnyvv was purified and a specific antiserum was p...

Exogenously supplied indole-3-acetic acid (IAA) stimulated ethylene production in tobacco (Nicotiana glauca) leaf discs but not in those of sugar beet (Beta vulgaris L.). The stimulatory effect of IAA in tobacco was relatively small during the first 24 hours of incubation but became greater during the next 24 hours. It was found that leaf discs of these two species metabolized [1-(14)C]IAA quit...

BACKGROUND Modification of leaf traits in sugar beet requires a strong leaf specific promoter. With such a promoter, expression in taproots can be avoided which may otherwise take away available energy resources for sugar accumulation. RESULTS Suppression Subtractive Hybridization (SSH) was utilized to generate an enriched and equalized cDNA library for leaf expressed genes from sugar beet. F...

to study the effect of variable irrigation in spring on water use efficiency, quantity and quality of root and sugar yield of two sugar beet cultivars shirin and rasolan, an experiment was conducted at safiabad agriculctura research center during 2003-04 and 2004-05 cropping seasons. the experiment was designed in  a split plot with four replications in which five water supply treatments 25, 50...

In this paper, we propose a robust disease detection method, called adaptive orientation code matching (Adaptive OCM), which is developed from a robust image registration algorithm: orientation code matching (OCM), to achieve continuous and site-specific detection of changes in plant disease. We use two-stage framework for realizing our research purpose; in the first stage, adaptive OCM was emp...

Schefflera arboricola is a flowering plant in the family Araliaceae; its common name is dwarf umbrella tree. It is an evergreen shrub and a popular ornamental plant, commonly grown as an indoor plant. During a sampling in 2015, a new leaf spot symptoms was observed on S. arboricola plants in several greenhouses in the Hamadan province, Iran. Most of the plants were se...
