Probability Density Function Transformation Using Seeded Localized Averaging

open access: yesIEEE Transactions on Nuclear Science, 2011
Seeded Localized Averaging (SLA) is a spectrum acquisition method that averages pulse-heights in dynamic windows. SLA sharpens peaks in the acquired spectra. This work investigates the transformation of the original probability density function (PDF) in the process of applying the SLA procedure.

Anthropogenic seed dispersal: rethinking the origins of plant domestication

open access: yes, 2020
It is well documented that ancient sickle harvesting led to tough rachises, but the other seed dispersal properties in crop progenitors are rarely discussed. The first steps toward domestication are evolutionary responses for the recruitment of humans as

PLANT DENSITY OF SEED PROPAGATED ARTICHOKE (CYNARA SCOLYMUS L.)

open access: yesActa Horticulturae, 2004
Using the earlier seed propagated cultivars treated with gibberellic acid (GA), it is possible to follow a similar (but slightly delayed) cycle of the most frequently used cultivar in Spain, the asexually propagated ‘Blanca de Tudela’. However, the vegetative growth of the treated plants is lower.

Density-Dependent Seed Predation of Quercus wutaishanica by Rodents in Response to Different Seed States

open access: yesAnimals, 2023
The predation and/or dispersal of Quercus seeds by rodents play an important role in the creation of the tree species. The present study examined the effects of community habitats on the predation and dispersal of Quercus wutaishanica seeds by rodents. We released seeds with densities set at 2, 4, 8, 16, and 32 seed square meter with litter cover, soil

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

open access: yesApplications 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.

Impact of the quality of organic amendments on size and composition of the weed seed bank [PDF]

open access: yes, 2011
In addition to improving the soil quality, organic amendments of soils may affect weed seed survival, emergence, growth and reproduction. This study evaluated the effects of applications of different qualities of organic amendments on size and ...

QTL identification for seed weight and size based on a high-density SLAF-seq genetic map in peanut (Arachis hypogaea L.)

open access: yesBMC Plant Biology, 2019
The cultivated peanut is an important oil and cash crop grown worldwide. To meet the growing demand for peanut production each year, genetic studies and enhanced selection efficiency are essential, including linkage mapping, genome-wide association study,

Desirable Host Plant Qualities in Wild Rice \u3ci\u3e(Zizania Palustris)\u3c/i\u3e for Infestation by the Rice Worm \u3ci\u3eApamea Apamiformis\u3c/i\u3e (Lepidoptera: Noctuidae) [PDF]

open access: yes, 2018
The rate at which an insect infests hosts by ovipositioning and/or subsequent growth of larvae often depends on specific desirable host plant qualities.

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

open access: yesElectronic 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
