Influence of biostimulant application on growth, nutrient status and proline concentration of begonia transplants

Begonia (Begonia semperflorens Link et Otto) belongs to a group of annual plants that are commonly grown in city parks, mainly due to their wide colour options and adaptability to grow either in full sun or semi-shade. Good quality of begonia transplants for early planting outdoors can sometimes be hard to achieve, due to unfavourable conditions early in the season, such as low temperatures leading to insufficient nutrient uptake and plant growth. The aim of this study was to investigate the use of biostimulants for improving the conditions for raising transplants for early outdoor planting. The experiments were conducted in a non-heated glasshouse and were set up as a split plot design with treated and untreated plants in 2009, 2010 and 2011. In each year, the treatment with biostimulant Radifarm®, in a concentration of 0.25% (Valagro SpA, Italy) was applied weekly for two months, while control plants were treated with water. At the end of experiment, the following parameters were recorded: fresh and dry weights of roots and above-ground plant parts, plant height, numbers of leaves and flowers as well as concentrations of total N, P, K+, Ca2+, Mg2+ and free proline in roots and above-ground parts. Plants treated with biostimulant had significantly higher values for all morphological parameters investigated. At the same time, higher concentrations of K+ were recorded in begonia roots, while significantly higher concentrations of total N, K+, Ca2+ and Mg2+ were recorded in above-ground parts of biostimulant-treated plants. Biostimulant application affected proline accumulation positively.
