Planting time, flurprimidol treatments recommended for Lachenalia

29.07.2016

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.

Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....

Im Focus: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...

Im Focus: World record: Fastest 3-D tomographic images at BESSY II

The quality of materials often depends on the manufacturing process. In casting and welding, for example, the rate at which melts solidify and the resulting microstructure of the alloy is important. With metallic foams as well, it depends on exactly how the foaming process takes place. To understand these processes fully requires fast sensing capability. The fastest 3D tomographic images to date have now been achieved at the BESSY II X-ray source operated by the Helmholtz-Zentrum Berlin.

Dr. Francisco Garcia-Moreno and his team have designed a turntable that rotates ultra-stably about its axis at a constant rotational speed. This really depends...
