Later planting dates, flurprimidol soak optimize plant appearance, marketability
In order to introduce new flowering plants to market, breeders and growers need proven strategies for producing healthy, compact plants during times of highest consumer demand. Determining optimal planting times to produce true-to-type, high-quality potted plants or cut flowers also translates to higher revenues for growers. A new study in June 2016 issue of HortTechnology offers recommendations about production practices for lachenalia, an ornamental plant that is gaining popularity among consumers.
Flurprimidol treatment influenced the inflorescence stem height and floret length of 'Rupert', and the latest planting date in the experiments produced the shortest plants.

Researchers Anna Kapczyńska and Małgorzata Malik, from the University of Agriculture in Kraków, said that interest in lachenalia is growing because of it rich palette of flower colors and unique spotted leaves. "Lachenalias have the potential to become an extremely attractive pot plant or cut flower given their variations in flower color and longevity," the authors said.
Kapczyńska and Malik investigated how applications of the plant growth regulator flurprimidol would affect the growth of 'Ronina' and 'Rupert' lachenalia. Bulbs were planted in November, December, January, and February. At each planting date, the researchers applied flurprimidol treatments either by soaking the bulbs before planting or by a single foliar spray at four different concentrations.
Analyses showed that all growth parameters tested (except the number of leaves) were influenced by the planting date; the shortest plants were obtained by planting bulbs on the latest date. The application of flurprimidol and its concentration affected length and width of leaves and number of days to flowering of both types of lachenalia.
Flurprimidol treatment influenced the inflorescence stem height and floret length of 'Rupert': the shortest and the widest leaves resulted from bulbs soaked in flurprimidol at 30 mg·L-1. Flurprimidol treatment reduced the first and second leaf length by 18% and 17% for 'Ronina' and 23% and 23% for 'Rupert', and increased the first and second leaf width by 13% and 15% for 'Ronina' and 17% and 20% for 'Rupert'. Compared with control plants, soaking the bulbs and spraying the leaves of 'Ronina' delayed the emergence of flowers for 3-5 days and 1-4 days, respectively.
"We recommend soaking bulbs in flurprimidol at the concentration of 30 mg·L-1 to improve plant appearance and marketing quality," Kapczyńska and Malik said.
The experiments also showed that day length greatly influences the growth and flowering of lachenalia plants. "Prospective growers should also consider the need for supplemental lighting during autumn-winter cultivation," the authors noted.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
