Effect of Pentakeep-V on Begonia x tuberhybrida 'Nonstop' line
2015
In this study the 5-amino-levulic acid containing Pentakeep-V nano-fertilizer was examined in 0.3 ml/l, 0.5 ml/l and 0.7 ml/l concentrations with irrigating or spraying treatment on Begonia x tuberhybrida ’Nonstop’ seedling production. The experiment was conducted in Zajzon, in a 300 m 2 heated plastic tunnel, from January 2012 to June 2012. Best result was obtained with 0.5 ml/l concentration in the case of all examined parameters. Pentakeep-V had positive effect in all examined concentrations with both ways of treatments on all measured parameters instead of plant height. The plant growing time was shortened thanking to the treatments. Using additional artificial light plants developed more and bigger flowers. Spraying was more effective comparing to irrigation. All the treatments had positive effect on chlorophyll content in the leaves. Summarizing Pentakeep-V nano-fertilizer can be offered in 0.5 ml/l concentration with spraying treatment in the seedling production of Begonia x tuberhybrida ‘Nonstop’. Additional light enhances the effect in most examined parameters that is needed in the general practice during short day growing period.     Â
