This study aims to determine the effect of twig (current year shoot) size on seed size variation and to test whether a seed size vs number tradeoff occurs for the twigs of subtropical broad-leaved species. Fruit-bearing twigs were sampled for 55 woody species (including 33 evergreen and 22 deciduous dicot species) from a southwest Chinese forest. Twig size, fruit size and number, and seed size ...

Proteomics approaches have been a useful tool for determining the biological roles and functions of individual proteins and identifying the molecular mechanisms that govern seed germination, vigour and viability in response to ageing. In this work the dry seed proteome of four Arabidopsis thaliana genotypes, that carry introgression fragments at the position of seed longevity quantitative trait...

The Bronze Age in Europe is a dynamic time characterised by an increase long-distance mobility and interaction, changes social organisation, technological advancements evolving agricultural practices. In particular, we see the range of crops grown from middle Age, including introduction new crops, such as broomcorn millet broad bean. However, evidence practices Croatia limited. This paper prese...

Objective: The main objective was to isolate and characterise a naturally obtain polysaccharides which have the property to formulate sustain release product. Methods: Tamarind Seed Polysaccharides (TSP) was isolated from seed of Tamarindus indica by crushed the seed into powder and boiled with water at 45 °C to extract the polysaccharides. After boiling for 12 h the supernatant liquids were co...

This research aimed to determine the soil seed bank and its relationship with environmental factors that have an influence in the distribution of the vegetation above the ground in an excluded area of natural grassland in the South of Brazil. Most of the 122 identified species in the seed bank were perennials. Data analysis indicated three distinct community groups, according to the size and co...

Introduction Sunflower seed is one of the most commonly consumed snacks in our country. Sunflower seeds are not only eaten as snacks but also are used as ingredients of breads, mueslies and bars in recent years. Sunflower seed allergy is seen rarely in children and may be presented as angioedema or anaphylaxis. Respiratory allergies have been reported previously in adults owning birds fed on su...

Experiments were conducted at the CSIR-Crops Research Experimental station at Kumasi, Ghana, to determine the effects of seed sorting and planting device on yield of maize in the 2014 major growing season. Two jab planters were used to plant sorted and unsorted seeds. The control treatment was cutlass planting of unsorted seed. One of the jab planters was imported from China; and the other was ...

Glyphosate-resistant Palmer amaranth is the most troublesome pest in Arkansas cotton production. The prolific seed production, high germination rate, and rapid growth coupled with the lack of post emergence herbicide control options make this species a constant threat to cotton farmers. Sustainable control of Palmer amaranth requires careful management of seed in the soil seedbank. To emphasize...

Increasing attention in invasion biology is being paid to measuring and understanding the impacts of invasive species. For plant invasions, however, the impact of invasion on soil seed bank communities has been under-studied. At six sites in southern Germany, we investigated whether areas invaded by Solidago gigantea and Solidago canadensis experienced a reduction in seed bank species richness,...

Few studies have evaluated seed predation in fragmented landscapes, in which lower species diversity is expected to modifying ecological interactions. The rates of seed removal by mammals were investigated in a continuous forest and two fragmented patches of Premontane Tropical Moist Forest, in Monteverde, Costa Rica. The composition of mammalian seed-predators in each site was recorded during ...
