October 12, 2016. Dartmouth, Nova Scotia – Acadian Plant Health™ (APH™) scientists have co-authored an article, recently published in the peer-reviewed journal SpringerPlus, that validates the ability of APH™ products to help plants cope with and overcome drought stress.  The experiments detailed in the article used thermal imaging to detect plant temperatures and observe the effect of drought stress on young soybean plants.  The experiments concluded that plants treated with an APH™ product maintained cooler temperatures while exposed to drought and were less affected.  In addition to plant temperatures, other parameters, such as stomatal conductance, were monitored to gain a better understanding of the exact level of physiological stress each plant endured throughout the experiments.

“When we re-watered the plants at the end of each experiment, we ultimately saw that a larger percentage of leaves on the treated plants were able to recover,” said APH™ scientist and co-author of the article, Katy Shotton.  “This is exactly what we were hoping to see because the more leaves a plant has, the more it is able to photosynthesize and reach its full production potential,” added Shotton.

Stomatal conductance, the rate of carbon dioxide entering or water vapor exiting the plant through its pores (stomata), was measured throughout the duration of each experiment.  At the beginning of the drought period in each experiment, APH™-treated plants retained more water in their leaves, were more hydrated, and healthier.  Mid-way through each experiment, treated plants were able to maintain a cooler and more ideal temperature as they were “exhaling” more water.  At the end of each experiment, treated plants were found to be “inhaling” more carbon dioxide, further confirming that they were ready to resume photosynthesis and growth earlier than the control plants.

“With drought conditions becoming a regular occurrence in many key agricultural markets, it is professionally and personally gratifying to work for a company that offers sustainable solutions to help plants deal with drought stress,” said another APH™ scientist and co-author of the article, William Neily.  “We are making great strides in showing the world that Acadian Plant Health™ products are effective and reliable when it comes to helping plants contend with a variety of environmental stresses,” added Neily.

President of APH, Roger Tripathi said, “We are proud of our science, the extraordinary efforts of our research team, and the remarkable results we are seeing with our products. Because we’re investing significantly in research and development, we are able to show that Acadian Plant Health™ solutions truly empower plants so that they can better deal with serious growing challenges like drought.”
