Case Study One - General Photosynthesis

Experiments into increased photosynthesis
In a variety of experiments, researchers at NASA, Cornell University and other research groups in the US, as well as at IVIA (Instituto Valenciano de Investigaciones Agrarias) and
the University in Cordoba in Spain have demonstrated the unique abilities of Harpin Alpha Beta to enhance photosynthesis.
The aim was to measure HALO Harpin Proteins effect on photosynthetic activity in a closed system growth chamber. This was equipped for simultaneous measurements of
multiple physiological parameters. After treatment with HALO, there were demonstrated significant increases in net photosynthetic rates that persisted for a number of days.
The finding that net photosynthetic activity is elevated in response to Harpin provides an important insight into how HALO produces enhanced growth and yield. Measurements made in tomato, grape, asparagus and strawberries have all shown increased photosynthetic activity in response to HALO application.

Result of test: HALO treatment increases daytime photo-synthesis and night time respiration in wheat plants. (See figure 2)
Wheat plants were grown through anthesis (anthesis is the period during which a flower is fully open and functional) phase in a closed system growth chamber (NASA Ames
Centre) permitting continuous measurement of photosynthetic activity. Photosynthetic rates were monitored both before and after treatment with HALO. Baseline measurements were made to establish the pre-treatment level of photosynthetic activity. Leaves were sprayed with HALO solution (20 ppm.) 30 minutes prior to the beginning of the daily photo period. Days 1, 2 and 3 represent the days following HALO application.
