Embothrium coccineum J.R. Forst. & G. Forst. (Proteaceae) is a tree that grows successfully in nutrient poor soils of southern Chile at full sunlight. Under these conditions it develops cluster roots (CR).However, the induction of CR on this species has not been studied completely. The aim of this work was to study the effect of seasonality, soil and weeds in the development of CR in E. coccineum. The present study was performed in Los Lagos Region (41º72 S lat), Chile. Plants of E. coccineum were grown in sandy soils in presence or absence of weeds, using two concentrations of organic matter. The number of CR per plant, CR mass and P concentration in leaves was measured during the four seasons in E. coccineum plants. The CR development in the... |

Abstract Plantain is the fourth most important crop in the world, considered as a basic and export product in Ecuador. The root distribution of three plantain cultivars (Musa AAB) grown in Ecuador was evaluated at the “Río Suma” Experimental Farm, “Laica Eloy Alfaro de Manabí” University, 0º15’ S, 79º26’ W. Plantain cultivars were ‘Barraganete’, ‘Curare Enano’ and ‘Dominico Hartón’, and root distribution was determined according to the phenology of plants (10, 20, 30, 40 leaves (inflorescence) and harvest), seeded at 2.5 m x 1.8 m. In a completely randomized block design with five replicates, five plants·cultivar-1 were selected for each evaluation. Root distribution was carried out in soil profiles between rows. The greatest root distribution occurred 20... |
