Assessment of the Destruction of a Fibre Cement Board Subjected to Fire in a Large-Scale Study (2022)

This article presents the results of a study involving the assessment of the structural destruction of fibre cement boards taken from a large-scale model subjected to fire. These were subjected to a three-point bending test using the acoustic emission method. The analysis of the obtained results took into account the course of bending stresses σm, the modulus of rupture (MOR), the number of acoustic emission events Nzd and the sum of EA events ∑Nzd. The conducted tests showed that the samples su

Hemp hurd and alfalfa as particle filler to improve the thermo‐mechanical and fire retardant properties of poly(3‐hydroxybutyrate‐co‐3‐hydroxyhexanoate) (2019)

The poor thermo‐mechanical and flame‐retardant properties of biopolymers are currently limiting their application and potential exploitation as sustainable polymers. The use of agricultural by‐products as a functional filler for biopolymers is here presented to address the production of environmentally friendly and economically sustainable biocomposites. To this aim, hemp hurd and alfalfa particles were melt‐blended with a poly(3‐hydroxybutyrate‐co‐3‐hydroxyhexanoate) (PHB) co‐polymer. The 30 wt

Review of seed yield components and pollination conditions in red clover (Trifolium pratense L.) seed production (2021)

AbstractRed clover (Trifolium pratense L.) is an important forage legume grown in many of the temperate regions around the world. In order to evaluate possible causes for the low seed yield in particular in tetraploid red clover, we surveyed 71 studies of red clover seed production published from 1948 to 2019, reviewing seed yield components, pollination and reproductive traits. Seed yield components are recorded to contribute to and improve our understanding of the complex processes leading to

Primary seed production of drug-free varieties of cannabis in the Middle Volga region (2021)

The article discusses the practical aspects of seed production of monoecious Ko noble planting. It is shown that the production of varietal seeds, maintenance of economically valuable traits, properties and preservation of biological purity of hemp varieties at a high level is possible only with a well-established seed production system. Long-term experimental data on the assessment of plants from 1-year breeding nurseries for the content of tetrahydrocannabinol (THC) by gas-liquid chromatograph

Pollination Timing and Hybrid Seed Production of Neoregelia (2020)

Neoregelia cultivars have been used in many areas for landscaping and indoors in a variety of creative ways, but scientific reports of their pollination and hybridization are presently limited. Cross-combinations of Neoregelia cultivars were created to define conditions for pollination timing and to evaluate cross-compatibility. Neoregelia cultivars have short-lived flowers. H

Rice Artificial Pollination (Crossing) Methods and Hybrid Seed Formation Indicators (2025)

This article presents the results of obtaining hybrid seeds through crossing (artificial pollination) in rice under Karakalpakstan conditions and evaluating their effectiveness. In the studies, "Sanam", "Guliston", "Javohir", "Brilliant" varieties and several lines were involved as female and male parents. Crossing work was carried out according to IRRI (International Rice Research Institute) methodology: emasculation was performed before flowering, male pollen was applied manually, and panicle

The Role of Pollination Services in Seed Production: A review (2023)

In the face of declining insect biodiversity, this study reviews the critical role of pollination services in seed production of food crops. Insects, as pollinators, play a fundamental role in the reproductive processes of both wild and domesticated plants, impacting global agriculture. While previous reviews have assessed the influence of pollinators on primary food production, this review extends to seed production, an essential precursor in the agricultural supply chain. Here we add to the ex
