| [picture infos + copyright as Mouse-Over, click thumbnails to enlarge images] | ||
| Experiments kick-off: cooperative tests on UVB stress. | ||
| Experiments kick-off: dry stress physiology performed by K. Schödl and Dr. M. Griesser. | ||
| Potted vines: transfer from cold chamber to greenhouse for acclimatization. |
|
|
| Metabolomic Profiling is now being performed basing on LTQ Orbitrap XL to further enhance resolution of metabolites. This analysis is conducted at IFA, Tulln. |
| |
| Potted vines: transfer for hibernation in Jedlersdorf. |
| |
| Preparation of leaf samples for analyses of polyphenols finished. |
| |
| In situ measurements of leaf spectra in the field plots of Retz and Krems employing Spectrometric and GPS-combined methods. |
| |
| UVB stress experiments in the field (Sandgrube, Krems) with two differing Riesling clones finished, sampling of leaves and berries, vinification of berries of different treatments in one vineyard. |
| |
| Thunderstorms affect field trials: storm in Langenois destroys test array (image), hailstorm damages in experimental plot Wien-Cobenzl |
| |
| UPDATE for Physiological Fingerprint project: spectrometric measurements integrated into the experimental design. In cooperation with Vienna Technical University, establishment of the methodology is being developed as basis for precision viticulture in Austria. |  |
|
| Start of UVB radiation field trials. In three plots (Retz, Krems, Langenlois) experiments with Pinot noir and Riesling cultivars are being conducted. |  |
|
| Start of field trials 2009 - plot inspection in Retz, Krems and Langenlois. |  |
|
| Greenhouse season 2009 kick-off: more than 650 vines were potted for experiments under controlled environmental conditions. |  |
|
