Genotypic variation in phosphorus efficiency between wheat cultivars grown under greenhouse and field conditions [PDF]

open access: yes, 2006
Phosphorus (P) efficiency (relative growth), which is described as the ratio of shoot dry matter or grain yield at deficient P supply to that obtained under adequate P supply, was compared in 25 winter wheat cultivars grown under greenhouse and field ...

Fine-grained Category Discovery under Coarse-grained supervision with Hierarchical Weighted Self-contrastive Learning [PDF]

open access: yesarXiv, 2022
Novel category discovery aims at adapting models trained on known categories to novel categories. Previous works only focus on the scenario where known and novel categories are of the same granularity. In this paper, we investigate a new practical scenario called Fine-grained Category Discovery under Coarse-grained supervision (FCDC).

A reductionist approach to dissecting grain weight and yield in wheat [PDF]

open access: yesJournal of Integrative Plant Biology, 2019
AbstractGrain yield is a highly polygenic trait that is influenced by the environment and integrates events throughout the life cycle of a plant. In wheat, the major grain yield components often present compensatory effects among them, which alongside the polyploid nature of wheat, makes their genetic and physiological study challenging.

Performance of winter wheat varieties in white clover living mulch [PDF]

open access: yes, 2008
The choice of variety for agricultural systems with multiple crops may differ from the one used in sole crop because of the changes in environmental conditions brought about by interspecific plant competition. Information about varietal performance under

Using the Starlight Polarization Efficiency Integral to Constrain Shapes and Porosities of Interstellar Grains [PDF]

open access: yes, 2021
We present a new method for using the observed starlight polarization and polarized submm emission to constrain the shapes and porosities of interstellar grains. We present the modified picket fence approximation (MPFA), and verify that it is sufficiently accurate for modeling starlight polarization.

Location of insects in a barley bulk-grain

open access: yesЗерновое хозяйство России, 2023
In order to reduce the loss of stored grain, it is important to detect insects in it at the early stages of infection, for which it is important to know their preferred habitats.

The Effect of Grain Position on Genetic Improvement of Grain Number and Thousand Grain Weight in Winter Wheat in North China

open access: yesFrontiers in Plant Science, 2018
Genetic improvements have significantly contributed to wheat production. Five wheat cultivars—widely grown in north China in the 1950s, 1990s, or 2010s—were grown in field experiments conducted in the 2014–2015 and 2015–2016 growing seasons.

Maize grain weight sensitivity to source-sink manipulations under a wide range of field conditions [PDF]

open access: yes, 2018
Physiological causes for grain weight determination in maize (Zea mays L.) are not clear. Source–sink relationships during grain filling modulate grain weight, and there are controversies regarding the degree of source limitation that may exist during ...

Estimation of sink capacity of rice grains: A comparison of calculation methods based on 1000-grain weight and grain projected area

open access: yesPlant Production Science, 2023
Accurate estimation of sink capacity in rice (grain number × potential grain size), independent of grain filling, is necessary for considering source – sink interactions. However, how to measure potential grain size is still a matter of debate.

Association between grain yield, grain quality and morpho-physiological traits along ten cycles of recurrent selection in bread wheat (triticum aestivum L.) [PDF]

open access: yes, 2017
The objective of the present investigation was to examine the relationships between agronomical behavior and grain quality along ten cycles of a recurrent selection program performed under rainfed condition. Twenty-four lines, four for each one of the 0,
