Pollen Genotype Effects on Seed Quality and Selection of Single Seeds by Near-Infrared Reflectance Spectroscopy (NIRS) in Winter Oilseed Rape
(2004-09-08)Oilseed rape is one of the most important oilseed crops of the world. Because of the success in quality breeding, the growing area of oilseed rape is gradually increasing. Although the seed ... -
Pollinator communities and plant-pollinator interactions in fragmented calcareous grasslands
(2007-08-01)Agricultural intensification has caused a substantial decline of once common semi-natural habitats in the agricultural landscape. Many calcareous grasslands, one of the most species-rich ... -
Pollinators and Ecosystem Services in an Oil Palm Transformation Landscape
(2022-09-27)Insect pollination is an economically important ecosystem service that depends heavily on wild pollinators. Landscape transformation caused by conversion to agriculture threatens habitats of wild pollinators, reducing their ... -
Population structure of Magnaporthe oryzae from different geographic regions and interaction transcriptomes with rice genotypes at high temperature
(2016-09-16)It is currently hypothesized that climate change may lead to global warming, and temperatures might increase by 2-5°C at the end of the twenty-first century. However, the consequences of the expected temperature elevation ... -
Potassium nutrition on tomato (Solanum lycopersicon L.) has an impact on production, postharvest behavior, and fruit sensory profile
(2021-02-04)Tomato (Solanum lycopersicon L.) is the most important vegetable in the world consumption and production. The fruits significantly contribute to human health, as they are rich in vitamins, minerals, sugars and antioxidants. ... -
Potassium uptake efficiency mechanisms and root exudates of different crop species
(2007-05-03)Potassium uptake efficiency is the ability of plants to take up sufficient K under low soil K availability. Plant species differ in their K uptake efficiency. This study was done with the ... -
Potential for Sustainable Poultry Production Based on Local Chicken Breeds and Regional Protein Plants
(2022-03-22)During the 20th century, poultry production evolved to a highly specific sector with special chicken lines for egg production on the one hand and meat production on the other. While of broilers both sexes can be used for ... -
Potential Impact of Increasing Ammonia Concentrations upon Microbial Population Dynamics in Anaerobic Meso- and Thermophilic driven Fermenters
(2020-02-06)Anaerobic digestion is the process of decomposition of organic matter by a microbial consortium in an oxygen-free environment. The produced biogas from this process is composed of methane, carbon dioxide, nitrogen, oxygen, ... -
Potential of the predatory pentatomid <i>Eocanthecona furcellata</i> (Wolff) as a biocontrol agent on American bollworm in cotton in Myanmar
(2008-06-02)The American Cotton Bollworm (Helicoverpa armigera Hübner)(ABW) is one of the most serious pests of cultivated crops, especially in cotton in Myanmar. Insecticide applications to control ... -
Predicting the intramuscular fat content in porcine M. longissimus via ultrasound spectral analysis with consideration of structural and compositional traits
(2011-05-10)This study aimed at improving the prediction of intramuscular fat (IMF) in porcine musculus longissimus via spectral analysis of the backscattered ultrasound signal on intact hot carcasses. ... -
Preference of dairy cows with free access to pasture and barn
(2024-12-12)With the increasing interest of various consumer groups in high welfare husbandry and the pressure on farmers to meet this demand, the number of comparative studies on dairy cow grazing and housing has also increased. ... -
Preference-performance relationships in herbivorous insects feeding on oilseed rape inoculated with soil-borne fungi
(2008-07-04)There is increasing evidence that plant-associated microorganisms are able to mediate plant-herbivorous insects-interactions. In this study, I evaluated the impact of two plant colonising ... -
