Exsertion, flowering and shedding in Panicum maximum (Poaceae) [PDF]

open access: yes, 1996
La floraison, l'exsertion et la maturation des graines ont été observées sur les panicules de quatre clones de #P. maximum$. Les relations à l'intérieur du clone et les différences entre clones ont été étudiées.

Genetic Analysis of Seed Set in Wheat (Triticum aestivum L.) Hybrids Generated With Cytoplasmic Male Sterility Versus Chemical Hybridization Agents

open access: yesPlant Breeding, Volume 144, Issue 6, Page 886-895, December 2025.
ABSTRACT The main challenge in hybrid wheat breeding is the low efficiency of hybrid seed production due to wheat's self‐pollinating nature. Efforts to improve cross‐pollination have mainly focused on enhancing pollen donor performance or increasing seed set in hybrids generated using chemical hybridization agents (CHA). Starting with 100 diverse wheat

Natural outcrossing and isolation distance requirements in exserted stigma tomato (Solanum lycopersicum) seed production

open access: yesThe Indian Journal of Agricultural Sciences, 2014
Genetic purity is of utmost important in seed production of varieties and hybrids. Since exserted stigma tomato types are much prone to natural crossing the chances of genetic contamination is higher in seed production and the recommended isolation requirements for hybrid seed production is higher (200m for foundation seeds and 100m for certified seeds)

The spatial distribution of a hummingbird‐pollinated plant is not strongly influenced by hummingbird abundance

open access: yesAmerican Journal of Botany, Volume 112, Issue 5, May 2025.
Abstract Premise Many angiosperms have evolved specialized systems that promote pollination by specific taxa. Therefore, plant distributions may be limited by the local abundance of their specialist pollinators. In eastern North America, Lobelia cardinalis is thought to be pollinated solely by Archilochus colubris, the only hummingbird species found in

Handbook of protocols for standardized measurements of floral traits for pollinators in temperate communities

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 5, Page 988-1001, May 2025.
Abstract Floral traits describe organs or structures directly related to plant reproduction, and they are essential to understanding plant–pollinator interactions, notably for conservation purposes. The growth of plant trait‐based approaches lies in the availability of data shared by the international research community on dedicated platforms, as well ...

Enhancing entomophilous pollination for sustainable crop production

open access: yesThe Plant Journal, Volume 122, Issue 4, May 2025.
SUMMARY Successful fertilization of insect‐pollinated crops hinges on a delicate interplay of olfactory and visual signals of pollinator attraction, the chemical complexity of nectar and pollen rewards, and the physical interaction between insects and flower anatomy for efficient pollen transfer.
