Tropical root crops: Production and uses in Africa: ProceedingsSummary: Se estudiaron los efectos de la sombra, N y K en la formacion de raices tuberosas en yuca. En expt. en macetas, la sombra retardo el inicio del engrosamiento cerca de 40 dias y redujo el tamano de las celulas tuberosas al igual que la distribucion de la MS hacia las raices tuberosas. En plantas tratadas con K, se detectaron raices tuberosas antes que en plantas sin fertilizar. El N no afecto la tuberizacion pero disminuyo significativamente el no. de raices tuberosas. El diametro y el peso de la raiz, el tamano y no. de las celulas de almacenamiento, y la distribucion de MS hacia las raices fueron significativamente mayores en plantas a las cuales se les suministro K, solo o en combinacion con N, pero fueron significativamente reducidos por la aplicacion de N sin K. (RA-CIAT)Summary: The effects of shade, N, and K on the formation of tuberous roots in cassava were studied. In pot expt., shade delayed initiation of bulking by about 40 days and reduced tuberous cell size and no. as well as DM diversion to tuberous roots. Tuberous roots were detected in plants treated with K earlier than in unfertilized plants. N did not affect tuberization but significantly increased no. of tuberous roots. Root diameter and wt., storage cell size and no., and DM allocation to roots were significantly greater in plants supplied with K, alone or in combination with N, but were significantly reduced by N applied without K.
