Seeds and plantlets of Myrciaria dubia “camu-camu”: biometry, germination, and initial growth
The objectives were to determine seed biometrics, recording cellular respiration in the imbibition process, evaluate the effect of inducing chemicals in germination and early growth analysis. Cellular respiration during imbibition was measured by reduction of methylene blue and Janus Green B. The in...

Initial growth was recorded by stereoscopic.
