Prolonged Cold Storage Affects Pollen Viability and Germination along with Hydrogen Peroxide and Nitric Oxide Content in Rosa hybrida

Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2016
Roses (Rosa hybrida) are the most important ornamental cut-flowers and breeders’ main focus is to develop new desirable modern cultivars. Rose breeding programs center on the introduction of new flower colors, thornless stems, higher production and ...

Storage of pollen grains of Crotalaria retusa in oils

, 1990
Attempts were made to store pollen grains of Crotalaria retusa L. in a mineral oil (paraffin oil) and two vegetable oils (soybean oil and olive oil). Under laboratory conditions pollen grains not stored in oil lost in vitro germinability within 15-30 ...

Linking regional and global functional trait data: insights from mammal communities in a fragmented Atlantic Forest landscape

Oikos, EarlyView.
Accurate functional trait data are essential for understanding ecosystem services and processes in fragmented landscapes. We evaluated whether the global EltonTraits 1.0 database adequately represents the functional structure of mammal communities in forest fragments and restoration sites in a highly fragmented Atlantic Forest landscape.

Microbial characterization of bee pollen from the Vesuvius area collected by using three different traps.

PLoS ONE, 2017
Flower pollen is collected by honeybee foragers, adhered on their rear legs and transported into the hives in the form of pellets. Once in the hives, bee pollen is moisturised with nectar and bee mouth secretions and due to enzymatically modifications it

The disruption of seed dispersal networks: disentangling the effects of habitat loss and fragmentation

Oikos, EarlyView.
Seed dispersal by frugivores is a central process linking plant reproduction, animal foraging, population persistence, and ecosystem resilience. Currently, the spatial template sustaining these interactions is rapidly reconfigured by habitat loss and fragmentation promoted by human activity.

Pollen Storage under Vacuum

, 1964
Pollens of 10 different genera have been evacuated for 2 hours to a final pressure of about 0.015 mm Hg. The pollen was stored in ampoules in vacuo at +5°C and at room temperature. The viability of the pollen was tested in all cases by germinability.

What turns us off about green and blue spaces in cities? Understanding perceived problems and unpleasant experiences for more just urban planning, design and management

People and Nature, EarlyView.
Abstract The planning, design and management of urban green and blue spaces necessitate trade‐offs between these spaces' many benefits and their drawbacks, but knowledge of perceived problems and unpleasant experiences in urban green and blue spaces remains limited.

Pollen viability and in vitro germination of six pistachio (Pistacia vera L.) cultivars grown in northern Jordan

Advances in Horticultural Science, 2019
This study was conducted on six pistachio cultivars (Lazaourdi, Nab-El Jamal, Boundiki, Batouri, Marawhi and Aschouri) to investigate the percentage of pollen viability and in vitro pollen germination under stored and non-stored (fresh) conditions.

Cryogenic Storage of Olive Pollen

Journal of the American Pomological Society
The possibility of using liquid nitrogen storage conditions (−196°C) for the storage of olive ( Olea europaea) pollen was demonstrated. Pollen from 10 cultivars was rapidly frozen and thawed. Germination tests were performed on 15% sucrose, 1% agar plates. Significant differences between unfrozen control samples and frozen pollen samples were not found.
