Book Chapter 1991

Autor: Cock, James H.

Development models are outlined to shed light on cassava's potential to generate economic growth. Since small cassava producers are to a large extent marginalized from the development process in Latin America, the CIAT cassava program has tried to define development strategies that are clearly or...

A series of trials were carried out using cassava. Crop growth rate increased with leaf area up to LAI 4; root growth rate increased up to LAI 3-3.5, then declined. LAI is determined by leaf size, leaf formation rate and individual leaf life. Leaf size reached a max 4 mo after planting and then d...

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...

Cassava (Manihot esculenta Crantz) is a staple food for a large sector of human population in the tropics. It is widely produced for its starchy roots by small farmers over a range of environments on poor infertile soils with virtually no inputs. It is highly productive under favorable conditions...

To determine the presence of Kranz anatomy, chloroplast structure and distribution in cassava leaf tissues, a selection was made among materials of CIAT`s germplasm bank. Two materials were selected, var. MCol 22 and hybrid CM 507-37; work was also carried out with maize var. Swan Laposta C48B (m...

Cassava, bean, and maize leaves were fed with (14)CO2 in light; the primary products of photosynthesis were identified 5 and 10 s after assimilation. In cassava, approx. 40-60 percent were incorporated in C4 acids with 30-50 percent in phosphoglyceric acid, which indicates that cassava possesses ...
