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. Nitrogen contributions of legume roots to cabbage nutrition
The effects of roots are generally not considered in studies assessing crop responses to green manure. However, measuring such effects can contribute to a better understanding of crop rotation. In two experiments, we evaluated the content of legume-N in crop tissue and the fertilizer value of the roots and shoots of two legume species. Roots, shoots, or whol

6. Acúmulo de ricina em sementes de mamona e silenciamento do gene em plantas geneticamente modificadas
Castor bean (Ricinus communis L.) is an oilseed of great economic and social importance. The oil extracted from its seeds is used in biodiesel production and as raw material for chemicals, cosmetics and lubricants. Besides the oil extracted from the seeds, their production chain generates side-products, which can be used as organic fertilizer of good quality

7. Potencial de enraizamento de estacas lenhosas de espÃcies florestais da mata ciliar / Potential for rooting of wood cutting species from riparian forest
The bioengineering has been used for the containment of slopes and ravines on the banks of watercourses. One of its tools is the use of hardwood cuttings planted directly in the field, but this requires that species have local adaptation with large capacity for rooting. Thus, this study had the objective of study the propagation by cuttings of native woody f

8. Análise do uso de água em unidades de produção de mudas de eucalipto / Analysis of water use in units of eucalyptus seedling production
This study was carried out in the seedling production units belonging to CAF (Santa Barbara Ltda - Agro-forestry Company), in the Municipal districts of Dionísio and Martinho Campos, Minas Gerais, from July 2004 to December 2006. The objectives of the study were to determine the water needs of eucalyptus seedlings, evaluate the irrigation systems and presen

9. Avaliação ecofisiologica de seringueiras (Hevea brasilienses Muell. Arg.), submetidas a diferentes intensidades de sangria, em ambientes contrastantes do Estado de São Paulo
Aiming to contribute to the adaptation of rubber tree tapping system to contrasting environments found in the State of São Paulo, Brazil, a research program was carried-out to assess environmental and plant variables, as well as physiological parameters related to relax production. The experimental areas were located in Registro, Ribeira Valley region, and

10. Evolution of nuclear ribosomal RNAs in kinetoplastid protozoa: perspectives on the age and origins of parasitism.
Molecular evolutionary relationships within the protozoan order Kinetoplastida were deduced from comparisons of the nuclear small and large subunit ribosomal RNA (rRNA) gene sequences. These studies show that relationships among the trypanosomatid protozoans differ from those previously proposed from studies of organismal characteristics or mitochondrial rRN
