The effects of mineral treatment and the amendments by organic and organomineral fertilisers on the crop yield, plant nutrient status and soil properties

open access: yesPlant, Soil and Environment, 2005
The studies were carried out as a pot experiment comprised of mineral treatments with farmyard manure, slurry and liquid organomineral fertiliser (Damishum) and finally the unfertilised control.

Heterogeneous Immunolocalisation of Zinc Transporters ZIP6, ZIP10 and ZIP14 in Human Normo- and Asthenozoospermic Spermatozoa

open access: yesCurrent Issues in Molecular Biology, 2022
Zinc (in the form of Zn2+) is necessary for male fertility. Both Zn2+ quantity and its localisation have been detected in seminal plasma and ejaculated spermatozoa, suggesting its active uptake via zinc import transporters (ZIPs).

The Fertilisation of Orchids [PDF]

open access: yesNature, 1877
WHILE botanising this spring in Portugal, I was struck with the fact that scarcely one of the orchids—species of Ophrys principally—that I had collected for my herbarium, or examined in the field, seemed to be fertilised, for none presented the least indication of having had pollen applied to its stigmatic surface; and I examined flowers in every stage
