Since inference concerning the relative effects of propagule pressure, biotic interactions, site conditions and species traits on the invasibility of plant communities is limited, we carried out a field experiment to study the role of these factors for absolute and relative seedling emergence in three resident and three non-resident confamilial herb species on a nutrient-poor temperate pasture....

Artificial excision of the distal part of acorns in order to promote germination is well researched in oak seedling cultivation studies. However, studies of combined effects of cotyledon excision and nursery fertilization on container seedlings are lacking, especially for seedling root growth and outplanting performance. This study aimed to explore the main effects of cotyledon excision on Quer...

A large body of research has documented the effect of seed priming ongermination, emergence and crop yield. In such research, seed priming has beenfound to have a positive, negative or no effect. Meta-analysis can help tosummarize and interpret a collection of experiments. The aim of this study was toconduct a meta-analysis to synthesize published data from studies addressing theeffect of seed ...

Seed and seedling predation may differentially affect competitively superior tree species to increase the relative recruitment success of poor competitors and contribute to the coexistence of tree species. We examined the effect of seed and seedling predation on the seedling recruitment of three tree species, Acer rubrum (red maple), Liriodendron tulipifera (yellow poplar), and Quercus rubra (n...

This study was carried out to investigate the effect of hydropriming on seed germination and seedling growth of five different flower seed species (Antirrhinum, Dahlia, Impatiens, Salvia and Zinnia). Hydropriming (20oC, 24 h), surface dried or dried back afterwards, was found to increase germination percentage, seedling emergence and fresh and dry weight. In all species, the maximum advantage i...

In order to test the feasibility of computer simulation in field maize planting, the selection of the method of single seed precise sowing in maize is studied based on the quadratic function model Y = A×(D-Dm)2+Ym, which depicts the relationship between maize yield and planting density. And the advantages and disadvantages of the two planting methods under the condition of single seed sowing ar...
