| Abstract:
Phytomonitoring technology is being introducing now world-wide in commercial greenhouses as a new information tool both for detecting physiological disorders in plants and for the fine-tuning of irrigation and climate control. Phytomonitor provides several interrelated plant measurements (leaf temperature, sap flow rate, stem diameter variations). Phytomonitoring analysis is based on monitoring of their trends and qualitative response to changed environment. In many sites, local horticultural experts and agronomists thoroughly supervise application of the phytomonitoring techniques. During May 1999- April 2000, the phytomonitoring system was used for improving production of roses in the “Solo-Shtil” commercial greenhouses (Shahar, Israel) under supervision of local experts. The outcome was significant. At first, the phytomonitor disclosed unexpected water deficit at nighttime. Then, it helped to examine the relieving effect of nighttime watering. Furthermore, the phytomonitor enabled experts to observe directly the favorable effect of root flushing on plant growth. Later on, the phytomonitor was used for scheduling application of flushing according to stem growth rate. In addition, many other improvements were made due to phytomonitoring control. The examination endures. | |
