1. Sugarcane root distribution and growth as affected by genotype and crop cycle
ABSTRACT Sugarcane (Saccharum L. spp. hybrids) is a globally important crop. While roots contribute to its net primary production, knowledge of sugarcane root growth is incomplete and limited in scope. The objective of this study was to determine cumulative root density (LA), root distribution, effective rooting depth (ERD), and root growth rate for four sug

2. Root growth and distribution in sugarcane cultivars fertigated by a subsurface drip system
Despite of the agronomic importance for water management, few studies of sugarcane roots have been performed under field conditions during the crop cycle. The aim of this study was to determine the cumulative root density (LA), root distribution on soil profile and the effective rooting depth (ERD) for three sugarcane cultivars using the minirhizotron method

3. O sistema minirhizotron no estudo da dinâmica de raízes.
ABSTRACT: Root dynamic is an important component of agricultural e natural ecosystems. The minirhizotrons system is a multicomponent assembly used to study root dynamics in a nondestructive manner. Basically, transparent tubes are installed in the soil and the root intersections along the tube are recorded and measured with appropriated software's. In this r

4. POSIÇÃO DOS GOTEJADORES E COBERTURA DO SOLO COM PLÁSTICO, CRESCIMENTO RADICULAR, PRODUTIVIDADE E QUALIDADE DO MELÃO / EMITHERS POSITION AND SOIL MULCHING WITH BLACK PLASTIC, ROOT GROWTH, YELD AND QUALITY OF MELON
Surface drip irrigation is widespread for the melon crop. To improve the efficiency of this system subsurface drip irrigation and plastic mulching can be used. These management practices can influence soil moisture, and growth and development of plants and hence fruit yeld and quality of melon. Root system can give good information for the design of the irri

5. Fine-root production dominates response of a deciduous forest to atmospheric CO2 enrichment
Fine-root production and turnover are important regulators of the biogeochemical cycles of ecosystems and key components of their response to global change. We present a nearly continuous 6-year record of fine-root production and mortality from minirhizotron analysis of a closed-canopy, deciduous sweetgum forest in a free-air CO2 enrichment experiment.
