Key Points

To evaluate the effects of the steroidal plant growth regulator Biobrás-16 on the growth of Psidium seedlings across different genotypes.
Used Biobrás-16 to treat Psidium seedlings under nursery conditions.
Measured root area and volume as indicators of growth response.
Assessed leaf pigment indices for stress mitigation effects.
Biobrás-16 significantly accelerated growth in Psidium seedlings, specifically increasing root area and volume.
The effectiveness of Biobrás-16 varied among different Psidium genotypes.
Leaf pigment indices indicated a reduction in stress for plants treated with Biobrás-16.

Abstract

• Biobrás-16 accelerates the growth of Psidium seedlings under nursery conditions. • Biobrás-16 increases root area and volume. • The response of Psidium to Biobrás-16 is genotype-dependent. • Leaf pigment indices indicate stress mitigation with Biobrás-16.
