Root architecture of Arabidopsis is affected by competition with neighbouring plants
Abstract How roots detect and respond to the presence of neighbors is relevant to understand plant belowground interactions. The aim of the present work was to evaluate the effect of the presence of neighboring plants and ...
Root-system of peanuts as affected by phosphorus fertilization
(Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA), 1994-11-01)
There have been some responses of peanut roots to phosphorus. An experiment was carried out to study peanut root growth and distribution as related to P in the soil. The cultivars Tatu, Oira and Tup4 and the lines FCA 170 ...
Kinetics of zinc uptake and anatomy of roots and leaves of coffee trees as affected by zinc nutrition
(Taylor & Francis Inc, 2005-01-01)
Zinc (Zn) uptake kinetics and root and leaf anatomy were studied in coffee trees grown in nutrient solutions with or without Zn. Leaves and roots were sampled and cuts were made in the medium part of the leaves and in root ...
Cotton root volume and root dry matter as function of high soil bulk density and soil water stress
Soil compaction reduces root growth, affecting the yield, especially in the Southern Coastal Plain of the USA. Simulations of the root restricting layers in greenhouses are necessary to develop mechanisms which alleviate ...
Mechanical and biological approaches to alleviate soil compaction in tropical soils: assessed by root growth and activity (Rb uptake) of soybean and maize grown in rotation with cover crops
Chiselling has been used to alleviate soil compaction but cover crops with deep, vigorous roots can improve root growth and activity of the cash crop for a longer time. The determination of root activity in addition to ...
Potassium supply to cotton roots as affected by potassium fertilization and liming.
(Pesquisa Agropecuária Brasileira, Brasília, v.38, nº 5, p. 635-641, maio 2003., 2011)
Corn root length density and root diameter as affected by soil compaction and soil water content
Negative effects of soil compaction have been recognized as one of the problems restricting the root system and consequently impairing yields, especially in the Southern Coastal Plain of the USA. Simulations of the root ...
Histological events during in vitro rooting of Nothofagus nervosa (Fagaceae)
(Taylor & Francis, 2005-12)
In vitro rooting protocols were previously performed on Nothofagus nervosa to optimise the culture medium and environmental conditions. A qualitative and quantitative tissue differentiation study during adventitious rooting ...
