Seminar and workshop dedicated to Walz PAM fluorometers

The Faculty of Agriculture of the Kobe University in Japan invites to a seminar with workshop on Walz PAM fluorometers. The event takes place on Thursday, May 23, 2019, from 10:00 to 17:00. Special emphasis is put on the DUAL-KLAS-NIR P700, Plastocyanin, Ferredoxin & Chlorophyll Fluorescence Measuring System. Lecturers are Dr. Ifuku, Dr. Klughammer, Dr. Kono, Dr. Miyake, and Dr. Wada. For detailed information write to mid@namoto.com.

GFS-3000 new control unit generation available

The new control unit 3200-C features a new generation of high performance, low weight batteries for power solutions: the eSMART 98 Wh batteries. Use the advantages of the new energy supply: simpler handling, less weight, and longer operation duration without battery change. Also, hot swap and battery storage becomes easier as the integrated capacity indicator shows the charge status of the batteries at all times.

DUAL-KLAS-NIR went into serial production

The market release of the DUAL-KLAS-NIR spectrophotometer promises to open a new era of PS I research under in vivo conditions. Ulrich Schreiber, monitoring the specific absorbance changes of ferredoxin under various experimental conditions, recently provided evidence that cyclic electron transport around PS I could be measured in plants with C3 photosynthesis using the DUAL-KLAS-NIR.

PHYTO-PAM-II MODULAR Version available

The PHYTO-PAM-II MODULAR Version is now available providing all advantages of PHYTO-PAM-II instruments. The MODULAR Version additionally features the opportunity to apply the software triggered Miniature Magnetic Stirrer PHYTO-MS to the bottom of the cuvette or to control the cuvette temperature by the Temperature Control Unit US-T.

Prototype of DUAL-KLAS-NIR spectrophotometer completed

Starting from the established DUAL-PAM-100 system, a “Kinetic LED Array Spectrophotometer” (KLAS) has been developed by Christoph Klughammer and Ulrich Schreiber. The device measures fast absorbance changes in the near-infrared range (NIR) concomitantly with green light-excited chlorophyll fluorescence. The ground-breaking system determines simultaneously the redox states of the PS I reaction center (P700), its electron donor plastocyanin, and its electron acceptor ferredoxin.

Walz and LemnaTec address physiological phenotyping

Chlorophyll fluorescence expert Walz GmbH and phenotyping specialist LemnaTec GmbH facilitate physiological measurements in plant phenotyping. By integrating a Walz IMAGING PAM camera into the LemnaTec Phenocenter, chlorophyll fluorescence measurements are enabled as part of an automated plant phenotyping procedure. The Phenocenter is a multi-sensor laboratory phenotyping system that automatically measures plants with different camera types. An adapted version of the approved Walz IMAGING PAM is one of the possible sensors available for the Phenocenter. Other cameras can be visible light and near-infrared cameras together with laser scanners and static fluorescence imaging. The multi-sensor approach enables comprehensive characterization of different aspects of plant phenotypes with particular focus on physiological data derived from chlorophyll fluorescence.

DIVING-PAM-II: First PAM system with spectrometer

As the first PAM fluorometer, the basic system of the DIVING-PAM-II includes a spectrometer to characterize the natural light environment, and to measure sample reflectance and fluorescence emission spectra. The spectrometer can also be connected to the MINI-PAM-II fluorometer.

MONITORING-PAM employed
in FACE experiment

Sponsored by the LOEWE program for top level research of the German Federal State of Hessen, researchers at Geisenheim University have set up a FACE (Free Air Carbon Dioxide Enrichment) experiment. Goal of research is to understand how future elevated CO2 levels, which drive the global climate change, affect viticulture and horticulture. Continuous recording of photosynthesis by MONITORING-PAM fluorometers provides long-term, time-resolved information on photosynthesis under coming climate conditions.

New MINI-PAM-II Chlorophyll Fluorometer now available

The MINI-PAM-II carries on the success of its predecessor “MINI-PAM” using most modern LED and computer technology. Operation and viewing of data occurs by a touchscreen which is easily readable in the field. Large storage capacity for data and commonly available spare batteries permit long-term research at remote places. A new fully digital leaf clip measures PAR, temperature and humidity.

PHYTO-PAM-II COMPACT Version available

Improved analysis capabilities for algal research. PHYTO-PAM-II COMPACT version features detailed assessment of photosynthetic performance. Due to its high performance, samples from natural sea water up to culture grown algae strains can be analyzed with highest accuracy and consideration of their spectral peculiarities. For mixed algae population, PHYTO-PAM-II provides differentiated, group-divided information about relevant photosynthetic parameters.

Walz IMAGING-PAM Identifies
Herbicide Resistant Weeds

German researchers have developed a breakthrough imaging method permitting rapid detection of herbicide resistant weeds. By measuring the maximum photosynthetic quantum yield of photosystem II (FV/FM), the method is much faster than established standard procedures.
