Germination and Storage of Genetiana Pollen [PDF]

open access: yes, 1967
Germination and storage condition of Gentiana pollen were studied. Sucrose solution was used as culture medium. The optimum sucrose concentration of medium was 10% in G. triflora and G. Zollingeri, and 15% in G. scabra var. Buergeri.

Studies on in vitro manipulation of male and female reproductive systems of flowering plants [PDF]

open access: yes, 1993
The overall aim of this research project is to investigate the possibility of using pollen as a vector for transporting extracellular substances to the site of gamete fusion in the embryo sac.

Standardization of different media for in vitro pollen germination of almond and evaluation of the germination capacity of stored pollen [PDF]

open access: yes, 2015
Almond is an important nut crop which, mostly for fruit set, needs the pollination of flowers followed by fertilization. Therefore, pollen viability and its germination capability are essential.

Pollen thermotolerance of a widespread plant, Lotus corniculatus, in response to climate warming: possible local adaptation of populations from different elevations [PDF]

open access: yesPeerJ
One of the most vulnerable phases in the plant life cycle is sexual reproduction, which depends on effective pollen transfer, but also on the thermotolerance of pollen grains.

Pollen Germination and Tube Growth in Northern Highbush Blueberry are Inhibited by Extreme Heat

open access: yesHortScience, 2023
The increasing intensity and frequency of extreme heat events threaten crop productivity globally. Certain phases of plant reproduction necessary for fertilization are highly sensitive to extreme heat, particularly during pollen development, germination,

The shared benefits of fallen fruits: A novel mechanism stabilizing a nursery pollination mutualism between Sambucus and kateretid beetles

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.

Functional analysis of the Arabidopsis thaliana AtEP3 endochitinase [PDF]

open access: yes, 2001
Chitinases are enzymes that are capable of catalyzing the hydrolysis of chitin, a homopolymer of N-acetylglucosamine. Chitin is the main constituent of the exoskeleton of insects, of crustacean shells and of the cell wall of many fungi but is absent in ...

Capsicum chinense as an African traditional vegetable: Culture, resilience, and opportunity

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Capsicum chinense is central to everyday diets, cultural identity, and smallholder livelihoods across Sub‐Saharan Africa, yet remains overlooked in agricultural research and policy. This paper reframes C. chinense as a traditional, climate‐resilient vegetable shaped by centuries of farmer stewardship and cultural selection.
