Ecological model for organizing the quantitative traits and method of orthogonal regressions were applied to evaluate both, aboveground root biomass grass pea varieties different originating. The study was conducted three years. highest yields fresh BGE015741 (840.40 kg/da), LAT4362 (779.3 kg da-1) BGE027129 (722.80 da-1). Plants BGE025277 have a higher weight mass exhibit good combination adap...
Sustainable nutrient management approaches could improve production and quality without affecting soil health. We conducted a field experiment to investigate the interactive effects of mulching (no mulch, plastic straw mulch) nanobiochar (NBC) foliar application on biomass, contents, metabolites in leaf curd cauliflower (Brassica oleracea var. botrytis). After 20 days transplantation, NBC (0.1%...
Many mechanisms of invasive species success have been elucidated, but those driving cryptic invasions of non-native genotypes remain least understood. In one of the most successful cryptic plant invasions in North America, we investigate the mechanisms underlying the displacement of native Phragmites australis by its Eurasian counterpart. Since invasive Phragmites ’ populations have been especi...
Ecosystems worldwide are increasingly impacted by multiple drivers of environmental change, including climate warming and loss of biodiversity. We show, using a long-term factorial experiment, that plant diversity loss alters the effects of warming on productivity. Aboveground primary productivity was increased by both high plant diversity and warming, and, in concert, warming (≈1.5 °C average ...
In a field experiment conducted in a Mediterranean area of inner Sicily, durum wheat was inoculated with plant growth-promoting rhizobacteria (PGPR), with arbuscular mycorrhizal fungi (AMF), or with both to evaluate their effects on nutrient uptake, plant growth, and the expression of key transporter genes involved in nitrogen (N) and phosphorus (P) uptake. These biotic associations were studie...
The measurement and assessment of aboveground tree biomass (bole, branches, and foliage), or M, plays a key role in the management of forest resources. Estimates are required for evaluating: a) the stocks and fluxes of several biogeochemical elements and b) the amount of primary energy obtainable from forests as an alternative to fossil fuels. Moreover, biomass is a fundamental state variable i...
Regrowth of tropical secondary forests following complete or nearly complete removal of forest vegetation actively stores carbon in aboveground biomass, partially counterbalancing carbon emissions from deforestation, forest degradation, burning of fossil fuels, and other anthropogenic sources. We estimate the age and spatial extent of lowland second-growth forests in the Latin American tropics ...
The proportion of tree growth allocated to stemwood is an important economic component of growth efficiency. Differences in growth efficiency between species, or between families within species, may therefore be related to how growth is proportionally allocated between the stem and other aboveground biomass components. This study examines genetically related differences in aboveground biomass a...
