A Predictive Model For The Effects Of Temperature On The Germination Period Of Flax Seeds (Linum Usitatissimum L.), Orhan Kurt
Turkish Journal of Agriculture and Forestry
Temperature is the most important factor in regulating the germination of nondormant seeds at the beginning of the growth season. The present study was conducted to produce simple regression models to predict how temperature affects the time it takes for 50% of a selection of flax seeds to germinate. R-square (r^2) values of regression coefficients of the equations established for flax cultivars varied from 0.899 (Antares) to 0.886 (Bionda). The optimum temperature for the time to germination for both cultivars was calculated using the coefficients obtained from the regression models. The optimum temperatures were found to be between 22.10 and …

Essential oils extracted by hydrodistillation from the aerial parts of naturally growing and field grown plants of Salvia cryptantha Montbert & Aucher ex Benthan were analyzed by GC-MS. Furthermore, the chemical components of naturally growing and cultured plants in 2 consecutive years (2007-2008) were compared. The essential oils of plant materials investigated ranged from 1.20% up to 1.52%. Nine for naturally growing and 22 components for both 2007-08 field grown crops were characterized, representing 94.75%, 95.82%, and 93.35%, respectively. Valencene (31.80%), eucalyptol (23.61%), and \beta-pinene (15.63%) were recognized as major components.

Plant growth retardants' applications have a practical use in fruit production, generally resulting in better vegetative growth and cropping level balance. Foliar applications of the gibberellin synthesis inhibitor prohexadione-Ca (ProCa), removal of young canes, and the combination of these treatments were evaluated in the Willamette raspberry (Rubus idaeus L). The experiment consisted of 5 treatments, including 1 untreated control.

Effect Of Irrigation On Processing Tomato Yield And Antioxidant Components, Lajos Helyes, Andrea Lugasi, Zoltán Pék
Turkish Journal of Agriculture and Forestry
A 2-year (2007 and 2008) open-field experiment was conducted to study the effects of irrigation on the yield parameters and main antioxidant components (lycopene, phenolic compounds, and ascorbic acid) of processing tomato. Two different treatments were applied: some plants were regularly irrigated, and some had their irrigation cut off 30 days before harvest. Both groups were compared with a rainfed control. Daily irrigation volume was calculated from the average daily temperature to reach optimum water supply. Fruits were harvested at the red-ripe maturity stage. The irrigated plants gave a significantly higher yield, and rainfed plants showed a yield loss. Irrigation …

Opium poppy (Papaver somniferum L.), an important plant of the family Papaveraceae, is valued for its extensive medicinal properties due to the presence of more than 80 different alkaloids, which are products of the polygenic interaction of different genes involved in plant metabolism. Broadening the genetic base through induced mutation is a supplementary tool that can lead to the development of genetic variability. The present study was undertaken to generate a broad genetic variability through mutation breeding using physical doses (gamma radiation of kR10 to kR50 at an interval of kR10), chemical doses (EMS of 0.2, 0.4, 0.6, and 0.8% …

Evidence For The Origin Of The B Genome Of Bread Wheat Based On Chloroplast Dna, Nadia Haider
Turkish Journal of Agriculture and Forestry
The hexaploid bread wheat Triticum aestivum L. (AABBDD) is thought to have originated through one or more rare hybridization events between Aegilops tauschii (DD) and the tetraploid Emmer wheat T. turgidum subsp. dicoccon (AABB). The progenitor of the A genome of T. aestivum has generally been accepted to be T. urartu. The origin of the B genome, however, is controversial and still relatively unknown. Research has found the B genome in T. turgidum to be closely similar to the S genome in section Sitopsis of Aegilops L.; the Sitopsis diploid species were thus proposed as the probable maternal parent in …

To study the effects of seed priming with solutions of Fe and B, each at concentrations of 0.5%, 1%, 1.5%, and 2%, and 1.5% Fe + 1% B, on the germination and yield of dill (Anethum graveolens), 2 separate laboratory and field experiments were conducted. The results of the laboratory experiments indicated that the effect of the studied treatments on the final germination percentage was significant. The seedling vigor index of dill was restricted when the Fe and B concentrations increased beyond 1.5% and 1%, respectively. The highest seed yield was recorded for the concentration of 1.5% Fe + 1% …

The effects of mixture of rice hull charcoal and pyroligneous acid (MRPA) and mixture of wood charcoal and pyroligneous acid (MWPA) with reduced rate of chemical fertilizer on the yield, and antioxidant and nutritional quality of rice were investigated. Results showed that RF (Recommended N-P-K fertilizer application = 110-55-48 kg ha^{-1}) generally had higher agronomic and yield components than MWPA and MRPA treatments while MWPA was more effective in improving the yield of rice than MRPA. The total phenolic compounds and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical electron-donating ability were improved at higher application rate of MWPA while xanthine oxidase (XO) inhibition was …

In this study, the water saving and conservation potential of various furrow irrigation management techniques for irrigated cotton were compared. Conventional every-furrow irrigation with open-end furrows (EFO) and blocked-end furrows (EFB), and alternate every-other-furrow management with open-end furrows (AFO) and blocked-end furrows (AFB), were considered. Considerable seasonal water savings were obtained with AFO and AFB flows, on average from 717 mm to 906 mm, respectively, when compared to EFO. Alternate furrows showed the ability to reduce tailwater runoff considerably. When compared with EFO, water use was reduced by 9063 m^3 ha^{-1} (60%) using AFB and 7167 m^3 ha^{-1} (48%) using …

Italian ryegrass (Lolium italicum L. cv. Tetraflorum) seed production is an important industrial activity in Serbia. Cleavers (Galium aparine L.) interferes in Italian ryegrass seed production as well as in many other crops. The effect of stand density of Italian ryegrass on its competitive interaction with cleavers was investigated in western Serbia in the 2005-2006 and 2006-2007 cropping seasons. The established density treatments of Italian ryegrass were 5 kg ha^{-1} seeding rate with 60 cm row spacing (SD_1), 5 kg ha^{-1} with 20 cm (SD_2), 20 kg ha^{-1} with 60 cm (SD_3), and 20 kg ha^{-1} with 20 cm (SD_4). …
