Summary: Tres clones de yuca, TMS 30572, TMS 4(2)1425 y 58308, cultivados en Ibadan, Nigeria, produjeron un prom. de 37 millones de flores/ha durante la estacion de cultivo de 1990. Las flores secretaron un prom. de 558.2 kg de nectar, equivalente a 234.8 kg de azucar. Los principales azucares presentes en el nectar fueron fructosa, glucosa y sucrosa, en proporciones aprox. iguales. El potencial prom. de miel de los 3 clones, estimado en 302.2 kg/ha, es entre los mas altos registrados. Aunque se sintetizaron tanto los azucares solubles como los glucosidos cianogenicos en las hojas de yuca, no se detecto la presencia de glucosidos cianogenicos en el nectar flora o en el nectar extrafloral (melaza). (RA-CIAT)Summary: Three cassava (Manihot esculenta Crantz) clones, TMS 30572, TMS 4(2)1425, and 58308, grown in Ibadan, Nigeria, produced an average of 37 million flowers per hectare during the 1990 growing season. The flowers secreted an average of 558.2 kg of nectar, equivalent to 234.8 kg of sugar. The main sugars present in the nectar were fructose, glucose and sucrose in approximately equal proportions. The average honey potential of the three clones, estimated at 302.2 kg per hectare, is among the highest reported. Although soluble sugars and cyanogenic glucosides are both synthesized in the leaves of cassava, no trace of cyanogenic glucosides was detected in the floral nectar or in the extrafloral nectar (honeydew).
