PLANT STRESS NEWS! Please read!
by Jez,Jakub 23 Dec '19

23 Dec '19

Dear friends, In the last weeks/months we have been investigating the plant stress issue, mainly focusing on the LED light spectrum. Always comparing to the fluorescent tube standard. Surprisingly, also the fluorescent tube setup shows same plant stress issues! Which was not the case in the very beginning when we have tested and decided for the new type of soil. See picture attached to this mail: Phytotron: #21 Soil: Gramoflor2006; not sieved; with perlite Light: Fluorescent tubes; LD Watering: Flooding twice a week Left side of the tray: WUXAL treated plants (once, after 1 month, 2ml/L) Right side of the tray: untreated plants Our new hypothesis focuses on the soil. In particular, on the soil composition and the available nutrients. From today’s point of view, it looks like the composition of the soil might have changed over the last months (without informing us); but this needs further investigation. The automated watering system (flooding) also eventually contributes negatively to the problem by washing out nutrients; twice a week. Also sieving might be suboptimal. Red leaves are known to be a symptom for Phosphor/Phosphate deficiency. We are in touch with the soil supplier and with APPN soil scientist from the BOKU to find a long-term solution. As a quick fix * you can fertilize your plants with WUXAL fertilizer which is available in the Facility (once after ~1month; 2ml/L; watering from the top). * Use a long-term fertilizer (OSMOCOTE) * Use the old type of soil ED63 Please contact Anneliese in case of questions for the quick fix. We will keep you posted on further steps and present you soon our final results and the long-term solution. Looking forward to your valuable feedback on your quick-fix results.

Construction works @PlantS Facility GMI and MFPL
by Jez,Jakub 29 Nov '19

29 Nov '19

Dear all, Next week small construction works are planned that might slightly affect the daily operation (mostly accessibility/corridor) of the Facility. In the next weeks we will also need to shut down phytotron #22 and #23 (one by the other) for a significant amount of time. No other phytotrons will be affected! GMI -1: Tuesday 3rd Dec and Wednesday 4th Dec Replacement of a pipe in the corridor (this particular pipe is not at all related to the operation of our Facility). MFPL 8th floor: 2.5 weeks from the 2nd December on CO2 System installation in #22 and #23 In case of any questions please do not hesitate to contact me.

NEW EXPERTISE @PlantS: Machine Learning, Data Analysis, Basic Statistics, Data Visualization and Scripting
by Jez,Jakub 21 Nov '19

21 Nov '19

Dear all, In the light of the upcoming high-throughput plant phenotyping infrastructure (PHENOPlant) and also the closure of the BioComp facility, we have extended and strengthened our service portfolio by providing expertise in: * Machine Learning (e.g. image segmentation & classification) * Data analysis and basic statistics (not strictly phenotyping data related) * Data Visualization * Tools/scripting (e.g. script-based workflow automation: experiment design, sample randomization, sample identification (QR codes), etc.) * Small, in-house hardware programming and electronics projects (see PHENOBox) in collaboration with the workshop powered by @Stewart,Ethan<mailto:ethan.stewart@vbcf.ac.at> (Staff Scientist) & @Seitner,Sebastian<mailto:sebastian.seitner@vbcf.ac.at> (Software Engineer; programmer of the PHENOBox). Supported languages: Python, C, R, Java, JavaSript and TypeScript. Please do not hesitate to contact me for further information and requests. Best, Jakub.
