Abstract:
Field pea (Pisum sativum L.) are planted on small area in Hungary, although it is a precious source of protein (22-28%), and it also plays a significant role like a component in fodder mixture and green forage. It is a great part in crop rotation as a short growing-season legume. Furthermore, it has beneficial effects of nitrogen-fixing nodules being able to obtain N derived from air. One of the most critical limiting factors is to find out weed management practise for control of weeds in field pea.

Methods. Etiolated seedlings of pea Maecenat variety were irradiated with selective light with different spectrum of RL (660 nm), GL (530 nm), BL (450 nm) to activate photoreceptor systems of plants. In 10-day-old seedlings, growth response was determined – linear growth and biomass accumulation, as well as indicators of antioxidant system – hydrogen peroxide content and activity of oxidases – catalase a

Abstract:
Many pests damage pea crops, which potentially leads to reduced quality and yield losses. Since pests occur at different phenological growth stages of pea crops, the prediction of growth stages, for example as BBCH stages, is beneficial. In this study, three models have been developed to simulate growth stages of grain and green pea crops, for the latter with early and late sowing dates. All data, such as BBCH stages and air temperature, were collected in Germany in a three-year study under practical farming conditions at 415 sample sites. For the development of each model, a Gompertz regressi

Abstract:
Legumes have been identified as a key element of food innovation and excellent candidates for ensuring sustainability in food systems. However, certain legumes, such as faba beans and legume by-products, such as pea pods, are currently mainly being used in animal feed rather than exploited and valued in human nutrition. In this study, the nutritional properties, anti-nutritional factors, and in vitro protein digestibility of pea pod flour and raw and thermally treated (80, 120, 150, and 180 °C during 30 min) faba bean flours were investigated. For pea pod flours, the results showed a very inte

Aim. The effect of chronic ultraviolet B (UV-B) radiation on shoots growth, content of photosynthetic pigments and hydrogen peroxide (HP) in the leaves of pea plants (Pisum sativum L.) was studied. Methods. Pea plants cultivar Gotivsky were irradiated by chronic UV-B during 5 days in the doses from 2.5 to 4 kJ/m2 per day with a power of 1 W/m2. The length of plant shoots was measured during 7 days after the end of radiation. Content of photosynthetic pigments and HP in leaves were measured on the 7 day after radiation. Results.

Abstract:
Summary The afila (af) mutation causes the replacement of leaflets by a branched mass of tendrils in the compound leaves of pea – Pisum sativum L. This mutation was first described in 1953, and several reports of spontaneous af mutations and induced mutants with a similar phenotype exist. Despite widespread introgression into breeding material, the nature of af and the origin of the alleles used remain unknown. Here, we combine comparative genomics with reverse genetic approaches to elucidate the genetic determinants of af. We also investigate haplotype diversity using a set of AfAf and afaf c

Abstract STUDY QUESTION Do selective serotonin reuptake inhibitor (SSRI) antidepressants affect the function of human sperm? SUMMARY ANSWER The SSRI antidepressant Sertraline (e.g. Zoloft) inhibits the sperm-specific Ca2+ channel CatSper and affects human sperm function in vitro. WHAT IS KNOWN ALREADY In human sperm, CatSper translates changes of the chemical microenvironment into changes of the intracellular Ca2+ concentration ([Ca2+]i) and swimming behavior. CatSper is promiscuously activated by oviductal ligands, but also by synthetic chemicals that might disturb the fertilization process.
