研究了外源施用植物生长调节剂 (PGR)、1-萘乙酸 (NAA)、6-苄氨基嘌呤 (BAP) 以及两者的混合物（NAA/BAP 混合物）对植物高度、植物长度的影响。三种不同富含植物大麻素（PCR）大麻基因型的腋枝、节间数量、生物量产量和大麻素含量。结果表明，施用 NAA (28%)、BAP (18%) 和 NAA/BAP 混合处理植物 (15%) 后，总株高显着降低。腋枝长度也显着减少 58% (NAA) 和 30% (NAA/BAP-mix)。 BAP并没有显着减少腋枝的长度。与未处理的对照相比，NAA (19%)、BAP (10%) 和 NAA/BAP 混合物 (14%) 减少了节间数量。 NAA 的应用影响了测试品种的植物结构。 KANADA 有利，导致更紧凑的生长习性，而花序产量（23.51 g 植物^-1 ）与对照（24.31 g 植物^-1 ）相比保持相似。 v. 0.2x 和 cv. 的花序产量。由于 PGR 的应用，FED 减少，而大麻素含量保持稳定。总体而言，PGR的应用可以在基因型特异性水平上使用，以有益地影响植物结构并优化单位面积的花序产量，从而优化大麻素产量，特别是在室内栽培空间有限的情况下。

Impact of Different Phytohormones on Morphology, Yield and Cannabinoid Content of Cannabis sativa L.

The impact of exogenously applied plant growth regulators (PGR), 1-naphthalenaecetic acid (NAA), 6-benzylaminopurine (BAP), and a mixture of both (NAA/BAP-mix), was investigated in regard to plant height, length of axillary branches, number of internodes, biomass yield and cannabinoid content of three different phytocannabinoid-rich (PCR) Cannabis genotypes. The results showed that total plant height was significantly reduced under the application of NAA (28%), BAP (18%), and NAA/BAP-mix treated plants (15%). Axillary branch length was also significantly reduced by 58% (NAA) and 30% (NAA/BAP-mix). BAP did not significantly reduce the length of axillary branches. The number of internodes was reduced by NAA (19%), BAP (10%), and the NAA/BAP-mix (14%) compared to the untreated control. NAA application influenced the plant architecture of the tested cv. KANADA beneficially, resulting in a more compact growth habitus, while inflorescence yield (23.51 g plant⁻¹) remained similar compared to the control (24.31 g plant⁻¹). Inflorescence yield of v. 0.2x and cv. FED was reduced due to PGR application while cannabinoid content remained stable. Overall, the application of PGR could be used on a genotype-specific level to beneficially influence plant architecture and optimize inflorescence yield per unit area and thus cannabinoid yield, especially in the presence of space limitations under indoor cultivation.
