Abstract: Root and shoot development of Dracaena fragrans 'Massangeana' was determined 51, 72, 93, and 114 days after fresh cut cane was planted. Basal circumference of canes varied from 13.5 to 19.5cm. At each sampling date, root:shoot ratio was affected by cane circumference. As cane circumference increased above 14.5cm, root length and root:shoot ratio decreased. Number of developing shoots was not affected by cane circumference at any sampling date. Leaf area was not affected until sampling day 114, when it increased as circumference increased. ----- Se evaluaron los efectos de seis tratarnientos sobre el desarrollo radicular en canas de Oreceene fragrans "Massangeana", Los tratamientos fueron: (a) aniIIado a 12cm. de Ia base de la catta, (b) anillados a 6 y I2cm. de la base de la cai{a, (c) muescado usando un grupo de tres pequenos incisiones horizontales a I2cm. de la base de la cana, (d) muescado unsando dos grupos de tres pequenos incisiones horizontales a 6 y 12cm. de las base de la caii'a, (e) cortes longitudinales utilizando tres incisiones de 12cm. de largo distribuidas cada 120 ualrededor de la caiia y, (f) control. Aunque el desarrollo radicular fue afectado por los diferentes tratamientos, la circunferencia de las caffas tambien ejercid' una fuerte influencia. Las canas con las mayores y menores circunferencias desarrollaron un sistema radicular menos extenso que aquellas de tamaiio medio, mientras que el optimo desarrollo foliar ocurrio' en aquellas caiias de circunferencia mayor.
