Different physiological characteristics of the cassava plant, which can be used as selection parameters, are reviewed, namely LAI, HI, biomass production, plants with amphistomatic leaves, and C4 photosynthesis. Experience indicates that it is better to select var. showing lower yield reduction u...

Se revisan diferentes caracteristicas fisiologicas de la planta de yuca que se pueden utilizar como parametros de seleccion: IAF, IC, produccion de biomasa, plantas con hojas amfistomatosas y fotosintesis C4. Se enfatiza que se debe tratar de seleccionar var. que presenten menor disminucion en co...

For seed crops, yield is the cumulative result of both source and sink strength for photoassimilates and nutrients over the course of seed development. Source strength for photoassimilates is dictated by both net photosynthetic rate and the rate of photoassimilate remobilisation from source tissu...

Cassava is an important energy-rich food for millions of people in tropical developing countries. The crop has reached that status after thousands of years of evolution under diverse agro-ecosystems, movement of germplasm within and across continents, and more recently, through scientific genetic...

In recent studies of cassava at CIAT, net CO2 uptake rates of 20 to 35 ?mol CO2 m?2 s?1 were commonly observed. Cassava photosynthesis has a high optimum temperature (35°C) and a wide plateau (25 to 35°C) corresponding to the temperature range under which cassava is cultivated. Leaf photosynthesi...
