Correlation between somatic heteromorphism and the germinative response of seeds of Mastichodendron foetidissimum (Jacq.) Cronq.
Mastichodendron foetidissimum (Jacq.) Cronq. is a tree characterized by heteromorphic seeds, which differ greatly in shape and size as a result of their number (1, 2 or 3) in each fruit. In this paper the correlation between this variability and the germinative response of the seeds was determined....

| description | Mastichodendron foetidissimum (Jacq.) Cronq. is a tree characterized by heteromorphic seeds, which differ greatly in shape and size as a result of their number (1, 2 or 3) in each fruit. In this paper the correlation between this variability and the germinative response of the seeds was determined. The seeds were classified into three categories, according to their shape (morphs I, II and III), corresponding to the number of seeds per fruit. For each morph, length, width, thickness, fresh weight, dry weight, content of humidity and percent of germination were determined. All the parameters differ between morphs, except the humidity content. The morphological variability shows a clear correlation with the germinative response: the heavier seeds (morph I) display the larger percentages of germination. |

Cronq. es un árbol con semillas heteromórficas que difieren en forma y tamaño en función de su cuantía (1, 2 ó 3) en cada fruto. En este trabajo se determina la correlación existente entre esta variabilidad y su respuesta germinativa. Las semillas fueron clasificadas en tres categorías de forma (morfos I, II y III), que corresponden al número con el que se presentan en el fruto. A cada morfo se le determinaron: longitud, anchura, grosor, peso seco, peso fresco, contenido en humedad y porcentaje de germinación final. Todos los parámetros difieren entre morfos salvo el contenido en humedad. Se observa una clara relación entre las diferencias en peso de las semillas y su respuesta germinativa: las más pesadas (morfo I) presentaron los mayores porcentajes de germinación.
