Chemical plant growth regulators (PGRs) are used in the production of ornamental potted and bedding plants. Growth control is needed for maximizing production per unit area, reducing transportation costs and to obtain a desired visual quality. However, the use of PGRs is associated with toxicity risks to humans and the environment. In many countries the availability of PGRs is restricted as few...

We investigated the influence of different conditions (light composition and plant growth regulators (PGRs) in culture media) on morphophysiological parameters Stevia rebaudiana Bertoni vitro vivo. Both PGRs light spectra applied were found to significantly affect morphogenesis. During micropropagation stage S. rebaudiana, optimal growth, with a multiplication coefficient 15, was obtained an MS...

Phlox paniculata L. and Rudbeckia hirta L. are popular North American native herbaceous perennials in the landscape. Perennials in general have a tendency to quickly outgrow their containers in the greenhouse. Chemical plant growth regulators (PGRs) are commonly used to control plant size in the horticulture industry. Unfortunately, both Phlox and Rudbeckia are extremely susceptible to powdery ...

The moderating role of salicylic acid (SA) and putrescine (PUS) as plant growth regulators (PGRs), on the growth parameters and phytochemical and qualitative characteristics of strawberry fruit 'Selva' under osmotic stress was investigated under soilless culture. The osmotic potential (salinity) of the nutrient solution containing different NaCl concentrations (0, 7.5, 15, 30 and 45 mM) and fol...

objective(s):the utilization of molecular techniques in the epidemiology of tuberculosis have provided an opportunity for using effective markers to trace the transmission of the disease .the purpose of this study was to compare the genetic patterns of mycobacterium tuberculosis by three methods of rflp technique. materials and methods: in a cross-sectional and prospective study, 95 strains of ...

Abstract Purpose In recent years, considerable research has been conducted on the use of plant growth regulators (PGRs) to improve crop yields. Large amounts PGRs are applied regulate growth. However, few studies have assessed impact PGRs, which leave soil residues, microorganisms, especially rhizobia. Methods this study, influence inoculation soybean roots with Sinorhizobium fredii and Bradyrh...

Purpose Postgraduate researchers (PGRs) appear to be particularly vulnerable mental health problems. Mental health-related stigma and discrimination may endemic within universities, creating a threatening environment that undermines PGRs’ well-being. These environmental characteristics increase absenteeism presenteeism, attendance behaviours have great personal institutional consequences. The s...

Here, efficient plantlet regeneration via somatic embryogenesis from Panax quinquefolium hairy roots was reported. Callus development was optimal on MS medium containing 2,4-dichlorophenoxyacetic acid (1 mg l) and -naphthalene acetic acid (1 mg l). After a 4-week growth, calli were transferred onto MS medium with different combinations of plant growth regulators (PGRs). The highest embryogenesi...

Abstract High rates of mental ill-health in postgraduate researchers (PGRs) represent a significant barrier to life satisfaction and academic success. Nevertheless, there is little knowledge about the extent origins health problems PGRs UK. The current study addresses this gap by investigating prevalence provenance anxiety, depression, sleep problems, subjective wellbeing, suicide behaviours An...

Abstract Worldwide, HEIs strive to provide the best possible training for their PGRs, next generation of researchers. PGRs engagement is crucial a successful completion training, however, research on experiences limited. Moreover, number international has increased steadily over last decade, which poses question whether have different levels compared local PGRs. Therefore, thus study aimed at f...
