A study of soil seed banks across one complete chronosequence of secondary succession in a karst landscape [PDF]

PeerJ, 2020
Anthropogenic disturbance and distinctive geochemistry have resulted in rocky desertification in many karst regions of the world. Seed banks are crucial to vegetation regeneration in degraded karst ecosystems characterized by a discontinuous distribution

A simple, non‐toxic method for separating seeds based on density, and its application in isolating Arabidopsis thaliana seed oil mutants

Applications in Plant Sciences, 2020
Premise Seed oil is an economically important trait in Brassica oilseed crops. A novel method was developed to isolate Arabidopsis thaliana seeds with altered oil content. Methods and Results In A.

Unravelling seed oil, protein and fiber density in lintlessfuzzless upland cotton (Gossypium hirsutum. L) through combining ability estimates and association studies

Electronic Journal of Plant Breeding, 2023
An investigation was carried out to understand the gene action for seed oil, seed protein, seed gossypol, seed cotton yield and fiber density through intra-hirsutum crosses. Combining ability and gene action were studied in eighteen hybrids involving

Invasive species control: incorporating demographic data and seed dispersal into a management model for Rhododendron ponticum [PDF]

, 2009
Rhododendron ponticum is a serious invasive alien plant in the British Isles and is of significant conservation and economic concern. Here, we integrate information on both the life-history and spatial dynamics of this species within an individual-based,

Effects of Seed Size and Cache Density on the Seed Fate of Quercus wutaishanica Mediated by Rodents

Life
Animal-mediated seed dispersal is very important for plant population regeneration and the stability of forest ecosystems. Seed size and cache density are important factors for seed dispersal, but we still know little about seed size selection at ...

Success of native hay-seed mix for dry grassland restoration: do not neglect the role of soil seed bank

, 2022
Ecological restoration has been proved to be an effective strategy to contrast biodiversity loss due to land use change. Among terrestrial ecosystems, dry grasslands represent biodiversity hotspot strongly threatened by soil consumption.

Spatial and temporal patterns of carabid activity-density in cereals do not explain levels of predation on weed seeds

, 2008
Seed predation is an important component of seed mortality of weeds in agro-ecosystems, but the agronomic use and management of this natural weed suppression is hampered by a lack of insight in the underlying ecological processes.

Comportamento de variedades de arroz de sequeiro em diferentes populações de plantas, com e sem irrigação suplementar Behaviour of upland rice varieties at different plant densities, under and without supplemental irrigation

Scientia Agricola, 1995
Visando determinar os efeitos do espaçamento entre linhas (30, 40 e 50 cm) e da densidade de semeadura (50, 100 e 150 sementes/m²) sobre o rendimento de grãos e algumas características biométricas de duas variedades de arroz (Oryza sativa L.), com e sem ...
