Com o objetivo de determinar o efeito da época de colheita no crescimento vegetativo, na produtividade e na qualidade de raízes tuberosas de três cultivares de mandioca (Manihot esculenta Crantz), desenvolveu-se em Araruna, Noroeste do Estado do Paraná, um experimento em área de Latossolo Vermelho Distrófico, no período de outubro de 1997 a maio de 1999. O delineamento experimental utilizado foi o de blocos completos casualizados, em esquema de parcelas subdivididas, com quatro repetições, sendo os tratamentos principais as cultivares Mico, IAC 13 e IAC 14 e os tratamentos secundários, dez épocas de colheita, realizadas mensalmente a partir do início do segundo ciclo de crescimento das plantas. A produção da parte aérea apresentou, no segundo ciclo,... |

The effect of harvest period on the quality of storage roots and leaves of cassava cultivars was determined in an experiment carried out in a randomized complete block design with four replications in a split plot scheme, with five cultivars in the plots and ten harvest times in the subplots. The IAC 13 cultivar had the highest rate of dry matter accumulation in the storage roots and the Mico cultivar the lowest. The period of least dry matter content in the storage roots occurred later for the Fécula Branca, Mico and IAC 14 cultivars, and the minimum starch content in the storage roots occurred later for the Fécula Branca and Mico cultivars. In general, the IAC 13, IAC 14 and Fécula Branca cultivars had higher dry matter content in the storage roots,... |

The objective of this work was to compare different phenotypic stability methods by using yield and storage root dry matter content data of eight cassava genotypes, assessed in eight environments in northwest of Paraná State, Brazil. All the methodologies applied showed to be able to study the stability of cassava genotypes, but each with its peculiarities. The methodologies of Eskridge, Annicchiarico and Lin and Binns were the most appropriated on situation with smaller effect of G x E interaction. The AMMI analysis and the Toler and Burrows methodology were the most specific on detailing specific adaptations of cassava genotypes to favorable and unfavorable environments. It could be suggested to use simultaneous AMMI analysis and Toler and Burrows... |

The objective of this work was to study the leaf production pattern and dry matter distribution in cassava during the second plant cycle. The completely randomized experimental design with four replications was used, with five cultivars in the main plots and ten harvest times in the sub-plots. Foliage production was affected by plant age, being higher in hot periods. Leaf blades and petioles dry matter content presented a linear increase due to a progressive decrease in the amount of young leaves and ontogenetic factors. The stems provided, temporarily, carbohydrates to the plant re-growth, delaying the availability and use of storage roots dry matter. The dry matter content in the storage roots was lower during the vegetative and higher during rest... |
