Effect of Pentakeep-V on Begonia x tuberhybrida 'Nonstop' line

Abstract

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.

Effect of 5-Aminolevulinic Acid (ALA) on the Biochemical and Physiological Parameters of Postharvest Quality of Polygonatum multiflorum L. All. ‘Variegatum’ Cut Foliage

“…In their analysis of the effect of ALA on the growth and senescence of pak choi leaves, Wei et al [49] evidenced that exogenously applied ALA both stimulates the production of chlorophyll and delays its degradation, thus inhibiting leaf aging. Similar conclusions were also formulated by Kisvarga et al [25], who found that ALA stimulates chlorophyll synthesis in the Begonia x tuberhybrida 'Nonstop' line. In the present experiment, there were statistically significant differences in the inhibition of chlorophyll degradation upon application of Pentakeep V at the concentration 0.04% during P. multiflorum growth.…”

“…b synthesis during the cultivation of Swiss chard exposed to salinity-induced osmotic stress. Also, Kisvarga et al [25] reported no differences in chlorophyll synthesis between Pentakeep V concentrations and ways of treatment in Begonia x tuberhybrida 'Nonstop' leaves.…”

“…Proline buffers cytosolic pH, protects subcellular compartments, and scavenges ROS [24]. ALA supplementation has a significant potential in ornamental plants sector and a positive effect on growth parameters and chlorophyll content was observed, i.e., for Begonia x tuberhybrida 'Nonstop' [25], Saintpaulia ionantha, Tillandsia usneoides [26], and Phoenix dactilifera 'Kalas' [27]. P. multiflorum can grow to a height of 80 cm in deciduous European and Asian forests (beech, oak, and hornbeam) [28].…”

The effect of different biostimulators on morphological and biochemical parameters of micropropagated Hosta ’Gold Drop’

“…The same (and higher: 0.5 ml l -1 ) dose was optimal for Saintpaulia ionantha (Tilly-Mándy et al, 2010b), because treated plants produced flowers two weeks earlier than the control and developed larger leaf-rozettes with higher chlorophyll concentration. Similarly, Begonia x tuberhybrida 'Nonstop' plants' growing time was shortened, and the chlorophyll contents of their leaves was higher especially when 0.5 ml l -1 Pentakeep-solution was sprayed (Kisvarga et al, 2015). Awad (2008) also experienced that the use of 0.04 or 0.08% Pentakeep-V resulted more chlorophyll and faster growing of Phoenix dactylifera 'Kalas': treated specimens got the value for marketable condition 4-5 months sooner than by the control plants.…”
