Soil effects on stem growth and wood anatomy of tamboril are mediated by tree age
(2021-08-01)
Soil influences the growth of trees and the characteristics of the wood; but could this influence change during the ontogeny of trees? To answer this question, we analyzed the wood anatomy of 9-year-old trees and 2-year-old ...
Production and quality of lettuce seed as a function of seedling age
(2020-07-03)
Age of lettuce (Lactuca sativa L.) seedlings can affect plant development after transplanting where older seedlings can delay development of plants after transplanting and lengthen the crop cycle. For seed production, when ...
Effect of environmental and phenological factors on the antimicrobial activity of Cochlospermum regium (Schrank) Pilg. roots
(Univ Estadual Maringa, Pro-reitoria Pesquisa Pos-graduacao, 2016-10-01)
Cochlospermum regium (Bixaceae) is a medicinal plant species native to the Brazilian savannah, known as the Cerrado. Local communities use its roots to treat infections of the female reproductive system. This study evaluated ...
Ageing and performance of warm mix asphalt pavements
(Elsevier B.V., 2017-08-01)
This paper presents results from investigating the ageing behaviour and performance of different warm mix asphalt (WMA) pavement mixtures also called energy reduced pavements. The mixtures were either prepared in the ...
Induced resistance against leafminer eggs by extrusion in young potato plants
(Taylor & Francis Ltd, 2007-07)
Egg extrusion patterns were investigated as an inducible defensive mechanism in potato plants against the leafminer Liriomyza huidobrensis (Blanchard) (Diptera: Agromyzidae). Increased multiplication rates in leaf cells ...
Changes in protein fractions, trypsin inhibitor and proteolytic activity in the cotyledons of germinating chickpea
(2001-09-01)
The chickpea seed germination was carried out in 6 days. During the period it was observed a little variation on total nitrogen contents, however the non protein nitrogen was double. A decrease of 19.1 and 20.6% in relation ...
Fatores que afetam a oviposição de Bemisia tabaci (Genn.) biótipo B (Hemiptera: Aleyrodidae) em tomateiro
(2002-12-01)
The aim of the present work was to determine the oviposition preference of the silverleaf whitefly on tomato (Lycopersicon esculentum). Preferred plant age and leaflet position on the plant were studied and the number of ...
Canonical correlations between agronomic traits and seed physiological quality in segregating soybean populations
(Funpec-editora, 2017-04-13)
The objective of this study was to evaluate the relationship between agronomic traits and physiological traits of seeds in segregating soybean populations by canonical correlation analysis. Seven populations and two ...

Wild cherries invading natural grasslands: unraveling colonization history from population structure and spatial patterns
(Springer, 2013-09)
Invasive success of many fleshy-fruited plants has been linked to opportunistic interactions with generalist frugivores. Prunus mahaleb is a small tree, producing large quantities of little, bright black, sugary drupes ...
