Development of species composition in long term simulations with an individual-tree growth simulator

Journal of Forest Science, 2009
The spruce-fir-beech dominated forest stands in Litschau in the Austrian part of the Bohemian Massif were converted by former forest management practices into pure Norway spruce stands and are now discussed to be reconverted into the potential natural ...

Yield statistics of interpolated superoscillations

, 2016
Yield Optimized Interpolated Superoscillations (YOIS) have been recently introduced as a means for possibly making the use of the phenomenon of superoscillation practical. In this paper we study how good is a superoscillation that is not optimal. Namely,

Yield and disease control in winter wheat in southern Sweden during 1977-2005 [PDF]

, 2009
Fungicides are routinely used to prevent yield losses in winter wheat in southern Sweden. Yield and 1000 grain weight (TGW) data from 432 trials in farmers’ fields were evaluated to review long-term yields (1977-2005) and control of eyespot and Leaf ...

The combined effects of cover design parameters on tomato production of a passive greenhouse [PDF]

, 2008
The objective of this paper is to demonstrate the need of a multiple design parameter approach to greenhouse design. To illustrate this need, we determined the combined effects of cover design parameters on tomato production of a passive greenhouse, that

Quantitative trait locus mapping for salt and drought tolerance traits in wheat (Triticum aestivum L.)

BMC Plant Biology
Background Wheat (Triticum aestivum L.) is susceptible to abiotic factors during its growth period, such as salt and drought. The germination stage is the initial growth stage of wheat growth, when wheat is particularly sensitive to salt and drought ...

A high yield neutron target [PDF]

, 1974
Target, in cylinder form, rotates rapidly in front of beam. Titanium tritide film is much thicker than range of accelerated deutron. Sputtering electrode permits full use of thick film.

Transcriptome analysis for understanding the mechanism of dark septate endophyte S16 in promoting the growth and nitrate uptake of sweet cherry

Journal of Integrative Agriculture, 2021
Sweet cherry is one of the most popular fresh fruits in the world. Previously, we isolated a soilborne dark septate endophyte (DSE) strain, S16, which promoted the growth of Gisela 5 sweet cherry rootstock.

Characterization of a wheat stable QTL for spike length and its genetic effects on yield-related traits

BMC Plant Biology
Spike length (SL) is one of the most important agronomic traits affecting yield potential and stability in wheat. In this study, a major stable quantitative trait locus (QTL) for SL, i.e., qSl-2B, was detected in multiple environments in a recombinant ...

TLidar-based crown shape indicates tree ring pattern in Norway spruce (Picea abies (L.) H. Karst) trees across competition gradients. A modeling and methodological approach

Ecological Indicators, 2023
Tree crowns and growth rings are physiologically and functionally connected through supporting and resource sharing. Management interventions may strongly influence tree growth by altering this linkage.
