Abstract
El estudio realizó en las aéreas circundantes del vivero forestal del Centro de
Investigación y Enseñanza Forestal, de la Facultad de Ciencias Forestales de la
UNAP, en el distrito San Juan Bautista, con el objetivo de determinar la mortalidad,
sobrevivencia, crecimiento en diámetro y altura en terreno definitivo de
Hymenolobium sp“ mari mari”; Vochysia, sp “quillosisa”; Aspidoperma, sp
“quillobordón”; Cedrelinga sp, “tornillo”; Peltogyne sp, “violeta”, sembradas con pan
de tierra y raíz desnuda. Los resultados fueron sometidos al análisis de varianza y
prueba de rangos múltiples de tukey:
A siete meses de la plantación la calidad de fuste del “mari mari” fue regular en
60% y 40% buena calidad. En “violeta” el 40% tuvieron calidad de fuste regular, en
“quillobordón” 30% y en quillosisa 10%. En tornillo un 60% tuvieron excelente
calidad y el 40% buena calidad. La sobrevivencia varió entre 49,72% y 81,79%, con
μ=72,71% y σ= 37,25% y cv=51,87%.El promedio de crecimiento mensual en altura
de los plantones varió entre 0,87 cm/mes y 6,25 cm/mes, con un μ= 2,5 cm/mes,
σ= 0,88 cm/mes y cv=34,4%. El crecimiento diámetro varió entre 0,85 y 0,88
cm/mes con μ=0,86 cm/mes, σ=2,03 cm/mes y cv=237,03%. La especie que más
creció fue Cedrelinga catenaeformis con 5,57 cm/mes de altura.
The study was carried out in the surrounding areas of the forest nursery of the Forest Research and Training Center, of the Faculty of Forest Sciences of the UNAP, in the San Juan Bautista district, with the objective of determining mortality, survival, growth in diameter and height in definitive land of Hymenolobium sp "mari mari"; Vochysia, sp "quillosisa"; Aspidoperma, sp "quillobordón"; Cedrelinga sp, "screw"; Peltogyne sp, "violet", sown with ground bread and bare root. The results were submitted to the analysis of variance and test of multiple ranges of tukey: Seven months after planting, the quality of the "mari mari" shaft was regular at 60% and 40% good quality. In "violet" 40% had regular shaft quality, in "quillobordón" 30% and in quillosisa 10%. 60% screw had excellent quality and 40% good quality. Survival varied between 49 transducer, 72% and 81.79%, with μ = 72.71% and σ = 37.25% and cv = 51.87%. The average monthly growth in seedling height varied between 0, 87 cm / month and 6.25 cm / month, with a μ = 2.5 cm / month, σ = 0.88 cm / month and cv = 34.4%. The diameter growth varied between 0.85 and 0.88 cm / month with μ = 0.86 cm / month, σ = 2.03 cm / month and cv = 237.03%. The species that grew the most was Cedrelinga catenaeformis with a height of 5.57 cm / month.
