Technique without label discovered thanks to Texas A&M University to research

METAIRIE, La., September 7, 2022 /PRNewswire/ — A technique used to test THC levels in hemp plants has now been confirmed to also identify the sex of the plant accurately without disrupting the growth cycle. Search results at Texas A&M University create a critical expansion point and valuable new use for Mariposa Technology’s state-of-the-art software and database.

Called PAMAP (for Predictive Analytical Modeling Application for Plants), this innovative digital agricultural tool has undergone an extensive research and development process to test live hemp plants for THC levels, among other cannabinoids, on-farm. , to ensure plants stay below the federal THC legal limit (0.3%) for industrial hemp.

Mariposa Technology uses the technique, known as Raman Spectroscopy (RS), for rapid field testing of industrial and pharmacological hemp for THC levels. On-site testing at farms growing hemp crops provides farmers with affordable, accurate, and immediate test results and provides the opportunity to supplement the work of testing labs.

Critical Risk Management for Plant Sex and THC

Identifying the sex of the plant is critical for hemp growers because one male or hermaphrodite hemp plant can pollinate an entire farm of female plants and negatively impact cannabinoid production. Only female cannabis plants can produce buds (flowers). Although male plants can be visually identified at around 6-8 weeks of growth, this is labor intensive and threatens the investment to date in cultivation.

“This discovery will be a game-changer for hemp growers around the world,” said Michael Adler, co-founder and CEO of Mariposa Technology. “In the past, growers had to be carefully trained to identify the sex of a plant. This can cause problems if a plant is misidentified and takes time. This new technique takes all the guesswork out, letting farmers know what they have. planted, saving them time and money.” He noted that PAMAP also allows hemp growers to quickly test the THC levels of live plants on the farm, positioning them to harvest before the levels of THC are considered “hot” and above the federal limits.

In the past, growers had to cut samples, send them to a lab, and wait days or weeks for results. This exclusive database allows anyone to test plants anywhere in minutes, without damaging the plant, for both sex and THC.

Mariposa Technology spent over a year traveling across the country collecting data on different varieties of hemp and marijuana plants using an Agilent Raman handheld spectrometer. This large-scale database is now used in conjunction with proprietary software, allowing an Agilent Resolve device (available through a subscription to PAMAP and Mariposa Technology) to test the sex of plants and the THC levels of their crop.

Academic research partnership

The sex determination technique was discovered by researchers from Texas A&M University and Mariposa Technology and recently announced in an article published in the academic journal Molecules. The authors found that by using a handheld Raman spectrometer, they can probe the biochemistry of plants, allowing them to identify hermaphrodites with 98.7% accuracy and male and female plants with 100% accuracy. .

“We recently discovered that we can use Raman spectroscopy to differentiate young male and female plants,” said Dr. Dmitry Kurouski, assistant professor of biochemistry, biophysics and biomedical engineering at Texas A&M University. “This innovative approach to optical detection is based on the phenomenon of inelastic light scattering that occurs between incident photons and molecules present in the sample. And the best part is that you can test each sample while allowing it to continue to grow.”

Identify the sex of the plant

Hemp is a dioecious plant, that is, it produces male, female and hermaphroditic plants. Female plants develop appendages that contain cannabinoids, molecules that include delta-9-terahydrocannabinol (delta-9 THC), cannabidiol (CBD), and cannabigerol (CBG). Male plants do not develop these appendages, making them useless to hemp growers producing pharmaceutical hemp. Additionally, hermaphroditic plants develop characteristics of both sexes, which can drastically alter the cannabis population due to hermaphrodite-induced cross-fertilization. Therefore, cannabis growers want to identify and eliminate male and hermaphrodite plants, and industrial hemp growers want to identify and eliminate female and hermaphroditic plants.

“When we learned about the work Dr. Kurouski was doing with RS and hemp, we realized there was an opportunity to harness this science to help hemp growers around the world,” said John Roberts, III, co-founder and president of Mariposa Technology. “Our partnership with Texas A&M allows us to continue to provide farmers with the latest research and a revolutionary tool that puts the power back in their hands so they can improve plant performance year after year.”

Following the release of this important research, Roberts said the company plans to launch a new fundraiser in the coming weeks to fund further development and deployment of the technology.
