GEOGRAPHIC AND GENETIC VARIATION OF GROWTH AND BIOMASS PRODUCTION IN COCOITE (Gliricidia sepium) UNDER TWO SOIL MOISTURE CONDITIONS

GEOGRAPHIC AND GENETIC VARIATION OF GROWTH AND BIOMASS PRODUCTION IN COCOITE (Gliricidia sepium) UNDER TWO SOIL MOISTURE CONDITIONS

An open-pollinated provenance-progeny test was established under two soil moisture conditions, in order to evaluate the variation in plant height and biomass production among and within nine populations of Gliricidia sepium (Jacquin) Kunth ex Walpers (cocoíte), as well as to identify the effects of water deficit on the structure of the phenotypic variation. Variation in height and biomass production was significant (p£0.05) among and within populations, even though their joint contribution to total phenotypic variation was less than 10 %. Interaction of moisture levels with populations and with families within populations accounted for an additional 10 and 3 % of total variation, respectively. Water deficit reduced height growth and biomass production of plants and modified the variance structure. Thus, under favorable moisture conditions, provenance variation contributed with 11 % of total variation, and families within populations added 4 %; however, under restricted moisture conditions, provenance variation was strongly reduced while the family-within-population variation was increased.

Se estableció un ensayo de procedencias y progenies de polinización libre, en dos condiciones de humedad en el suelo, con el objeto de evaluar la variación en el crecimiento en altura y producción de biomasa entre y dentro de nueve poblaciones de cocoíte [Gliricidia sepium (Jacquin) Kunth ex Walpers], así como para evaluar los efectos de la restricción de humedad sobre la estructura de la variación fenotípica. Los resultados indicaron la existencia de una variación significativa entre poblaciones y dentro de ellas, en el crecimiento en altura y producción de biomasa, aunque en conjunto aportaron menos de 10 % de la variación fenotípica total. La interacción de los niveles de humedad con las poblaciones aportó cerca de 10 % de la variación total y la interacción con las familias contribuyó con 3 % adicional. La restricción en humedad disminuyó el crecimiento en altura y la producción de biomasa de las plantas, y modificó la estructura de las varianzas. Así, en condiciones favorables de humedad, las poblaciones aportaron 11 % de la variación total en el crecimiento en altura y las familias dentro de poblaciones contribuyeron con 4 %, pero en condiciones de humedad restringida la variación entre poblaciones se redujo considerablemente y aumentó la varianza dentro de poblaciones.
