Paclobutrazol treatment as a potential strategy for higher seed and oil yield in field-grown camelina sativa L. Crantz

<p>Abstract</p> <p>Background</p> <p><it>Camelina (Camelina sativa </it>L. Crantz) is a non-food oilseed crop which holds promise as an alternative biofuel energy resource. Its ability to grow in a variety of climatic and soil conditions and minimal requirements of agronomical inputs than other oilseed crops makes it economically viable for advanced biofuel production. We designed a study to investigate the effect of paclobutrazol [2RS, 3RS)-1-(4-Chlorophenyl)-4,4-dimethyl-2-(1H-1,2,4-triazol-1-yl)pentan-3-ol] (PBZ), a popular plant growth regulator, on the seed and oil yield of <it>Camelina sativa </it>(cv. Celine).</p> <p>Results</p> <p>A field-based micro-trial setup was established in a randomized block design and the study was performed twice within a span of five months (October 2010 to February 2011) and five different PBZ treatments (Control: T₀; 25 mg l^-1: T₁; 50 mg l^-1: T₂; 75 mg l^-1: T₃; 100 mg l^-1: T₄; 125 mg l^-1: T₅) were applied (soil application) at the time of initiation of flowering. PBZ at 100 mg l^-1concentration (T₄) resulted in highest seed and oil yield by 80% and 15%, respectively. The seed yield increment was mainly due to enhanced number of siliques per plant when compared to control. The PBZ - treated plants displayed better photosynthetic leaf gas exchange characteristics, higher chlorophyll contents and possessed dark green leaves which were photosynthetically active for a longer period and facilitated higher photoassimilation.</p> <p>Conclusion</p> <p>We report for the first time that application of optimized PBZ dose can be a potential strategy to achieve higher seed and oil yield from <it>Camelina sativa </it>that holds great promise as a biofuel crop in future.</p

Urogenital chlamydia infection in women: patient management tactics according to present-day foreign and Russian recommendations

The article present data on current approaches to laboratory diagnostics and treatment of urogenital chlamydia infection in women. According to Russian and foreign guidelines, azithromycin, josamycin and doxycycline monohydrate belong to the most efficient antimicrobial drugs for the treatment of urogenital chlamydia infection in non-pregnant women. As for the treatment of pregnant patients suffering from this pathology, azithromycin and josamycin are the most optimal drugs in terms of safety and treatment efficacy according to both Russian and foreign guidelines

The detection rate of chlamydial and gonococcal infections and specifics of sexual behavior among women of reproductive age

Gonococcal and chlamydial infections are the most common sexually transmitted infections globally. Every year 250 million new cases of gonorrhea and 90 million new cases of urogenital chlamydia are registered worldwide. [21

Bacterial vaginosis: new treatment prospect

Bacterial vaginosis is an infectious non-inflammatory syndrome characterized by replacement of normal microflora (mainly lactobacilli) with polymicrobial associations of anaerobes and Gardnerella vaginalis. Recently, the molecular biology techniques showed that there is a much greater variety of microorganisms associated with bacterial vaginosis than previously thought. Clindamycin has demonstrated its efficacy and safety in the treatment of bacterial vaginosis today

Modern prospects for treating genital herpes

The review focuses on the clinical and epidemiological characteristics of herpes viral infection, in particular genital herpes. The current treatment options for recurrent genital herpes are presented. The main mechanisms of action of acyclic nucleosides are presented. A detailed description of valaciclovir (Valvir) is given

Bacterial vaginosis. New concepts of microbial biological environment and treatment options

Bacterial vaginosis is an infectious non-inflammatory syndrome characterized by replacement of normal microflora with polymicrobial associations of anaerobes and Gardnerella vaginalis. These microorganisms have the ability to grow on the mucosa, the so-called biofilm. Metrogyl vaginal gel is proposed as a potential remedy for the treatment of bacterial vaginosis
