Impact of Plant Growth Regulator NAA on Cannabis

Impact of Plant Growth Regulator NAA on Cannabis Professor DeBacco Hormones Explained 1-naphthaleneacetic acid (NAA) NAA is a synthetic (does not occur naturally) plant hormone in the auxin family that is also toxic in high concentrations to plants. Common ingredient in many commercial plant rooting horticultural products 6-benzylaminopurine (BAP) BAP is a first-generation synthetic cytokinin that causes plant growth and development responses such as setting blossoms and stimulating cell division It is an inhibitor of respiratory kinase in plants, and increases post-harvest life of green vegetables Reference Article Burgel, L., Hartung, J., Schibano, D., & Graeff-Hönninger, S. (2020). Impact of Different Phytohormones on Morphology, Yield and Cannabinoid Content of Cannabis sativa L. Plants, 9(6), 725. https://www.mdpi.com/2223-7747/9/6/725 Mean Plant Height Mean plant height over all three tested genotypes treated with (A) 1-naphthaleneacetic acid (NAA) (B) 6-benzylaminopurine (BAP) Means covered with at least one identical lowercase letter did not differ significantly at = 0.05. The arrows show the period (6 to 90 DAP) during which application took place. Mean Number of Internodes Mean number of internodes per axillary branch over two tested genotypes (KANADA and 0.2x-genetic) Means covered with at least one identical lowercase letter did not differ significantly at = 0.05. The arrow shows the time point (6 DAP) of the first application. treated with (A) NAA, (B) BAP Mean Length of Axillar Branches Median length of axillar branches in cm over all three tested genotypes treated with (A) NAA (B) BAP Means covered with at least one identical lowercase letter did not differ significantly at = 0.05. The arrow shows the time point (6 DAP) of the first application. PGR’s Impact on Cannabis Sativa The results of this study showed that exogenously applied plant growth regulators (PGR), namely 1-naphthaleneacetic acid (NAA), 6-benzylaminopurine (BAP) had significant impacts on the plant architecture of C. sativa. Both PGR’s lead to a more compact plant morphology The use of NAA led to a more compact plant architecture with a consistently high inflorescence yield for the genotype KANADA Cannabidiol (CBD) content was not affected. No Approved PGR’s In the cultivation of medicinal grade Cannabis production, there are currently no approved PGR to modify plant architecture. The use of PGR in production under good manufacturing practice (GMP) or good agricultural and collection practice (GACP) guidelines is not clearly defined, so any products applied to plants should be documented. PGR’s Impact on Plant Morphology It is important to note that the use of PGR did not reduce biomass yield and the content of cannabinoids. Goal was to produce small, compact plants intended for indoor growing environments. Impact of the Hormone Treated Plants NAA short habit reduced number of internodes significant the shortest axillary side branches BAP shorter habit reduced numbers of internodes shorter axillary side branches Degradation Synthetic IAAs (Indoleacetic acid) are more stable than endogenous IAA, and are degraded at a slower rate Know the Application and Concentration When using synthetic PGR, it is very important to know exactly the appropriate application methods and concentrations to avoid potential negative impact on the final product. Important note with IAA is that high concentrations are toxic and can utilized as an herbicide.
