Abstract
Abstract
Background
Oiti (Licania tomentosa[Benth.] Fritsch)
is an option for urban forestation and rural environments that require
shading by plants, so studying the plant environment to obtain quality
seedlings is essential. The present study aimed to evaluate oiti
seedlings in different protected environments with or without reflective
material on a cultivation bench.
Methods
The following protected environments were evaluated: an agricultural
greenhouse covered with a low-density polyethylene film and a
thermo-reflective screen with 42%/50% shading under the film; an
agricultural screenhouse with an aluminized screen with 35% shading; an
agricultural screenhouse with a black screen with 30% shading; and an
agricultural screenhouse with a black screen with 18% shading.
Production systems with and without photosynthetically active
radiation-reflecting material (aluminized screen,
Aluminet®) on the cultivation bench were
assessed in each protected environment.
Results
There was no interaction between the environmental factors; however,
the environments influenced height, stem diameter, root dry matter, and
total biometric relationships and growth rates. The reflective material
did not improve the quality of oiti seedlings. The ratio of shoot and
root dry matter was, on average, 71% for the shoots and 29% for the
roots. The photosynthetically active radiation received by oiti
seedlings ranged from 600 to 1,100 μmol
m−2s−1.
Conclusions
The greenhouse with 42%/50% shading screen under the film and the
black screen with 30% shading were the best environments for the
formation ofLicania tomentosaseedlings. The
reflective material on the cultivation bench did not result in better
quality oiti seedlings.
