An Anatomically Preserved Cone-like Flower from the Lower Cretaceous of China

open access: yesLife, 2023
Although diverse fossil angiosperms (including their reproductive organs) have been reported from the Early Cretaceous, few of them are well-documented due to poor preservation and limited technologies available to apply. For example, paraffin sectioning,

Morphological characteristics of the plant and reproductive capacity of yarrow (Achillea millefolium L.) seeds in dependence on pedo-ecological conditions

open access: yesSelekcija i semenarstvo, 2022
The paper analyzes the influence of soil type and its agrochemical characteristics on the morphological and productive parameters of different yarrow (Achillea millefolium L.) populations. At 8 locations the following fertility parameters were analyzed: pH (H2 O), pH (KCl), CaCO3 (%), humus (%), total N (%), available P2 O5 and K2 O (mg 100 g-1 soil ...

Changes in Reproductive Traits in Physalis philadelphica; An Unexpected Shift Toward Self-Incompatibility in a Domesticated Annual Fruit Crop

open access: yesFrontiers in Plant Science, 2021
Domestication is an evolutionary process with an impact on plant reproduction. Many domesticated plants are self-compatible (i.e., they lack mechanisms to reject their own pollen), but few domesticated plants are fully or partially self-incompatible.
