The objective of this study was to evaluate the effect of paclobutrazol on vegetative growth and <em>dry </em>matter <em>partitioning</em> in the potato plant cv. Markies, cultivated under summer conditions in the state of Minas Gerais. The treatments were 0.1, 1.0, 10 and 100 mg L<sup>-1</sup> of paclobutrazol (PBZ), applied to sprouted seeds before planting and control with water. PBZ was efficient in reducing plant height. The PBZ treatments with doses of 10 and 100 mg L<sup>-1</sup> delayed the emergence of shoots and the beginning of plant tuberization. PBZ at 0.1 mg L<sup>-1</sup> reduced the lengh of the stem by 18% but did not differ from the control for the fresh and dry mass content, total production, specific gravity and starch content of tubers. The treatment with seed potatoes and PBZ at 0.1 mg L<sup>-1</sup> resulted in smaller, more compact plants, which could be suitable for more densely planted cultivations in order to maximize plant populations and increase economic return per unit of area.</p>}, number={1}, journal={Revista Colombiana de Ciencias Hortícolas}, author={Araújo, Fernanda Ferreira de and Santos, Mirelle Nayana de Sousa and Araújo, Nícolas Oliveira de and Silva, Tania Pires da and Costa, Lucas Cavalcante and Finger, Fernando Luiz}, year={2020}, month={Jan.}, pages={135–143} }
