Determinação do efeito da copa da variedade dande Manihot glaziovii Onto, de copa j maior, quando enxertada sobre a variedade gangassol Manihot esculenta Crantz, de copa menor

Abstract

It has been normal to use grafting as a method to obtain improvements in aerial parts of some plants with a view to better fruit quality, better resistance to pests and diseases, etc.. In the present case, the aim was to achieve satisfactory results on the roots, by grafting dande (M author glaziovii Onto) of larger canopy, but without the capacity to form reserve roots, onto gangassol (Maniot esculenta Crantz) of smaller canopy, but with the capacity to form reserve roots. This treatment was compared with two others containing ungrafted gangassol and dande. The results showed a significant increase in the production of fresh roots and in the percentage of dry matter when grafting is done. On the other hand, it was observed that this treatment increases the cyanide content in the roots. This technology, despite being laborious, can improve the level of productivity currently recorded in Mozambique. (Traduçao NOSSA)
