Effects of Alternaria alternata f.sp. lycopersici toxins on pollen [PDF]
, 1988 Effects of the phytotoxic compounds (AAL-toxins) isolated from cell-free culture filtrates of Alternaria alternata f.sp. lycopersici on in vitro pollen development were studied. AAL-toxins inhibited both germination and tube growth of pollen from several

American Journal of Botany, EarlyView.Abstract Premise Climate change is altering the timing of many plant phenological events, yet most studies focus on flowering, with less attention given to later reproductive stages such as fruit development and ripening. Vaccinium angustifolium (lowbush blueberry) is an important perennial berry species that may be sensitive to these changes.

Morphology and viability of pollen grains from passion fruit species (Passiflora spp.)
Acta Botânica Brasílica, 2013 The characterization and viability of pollen grains are useful tools to guide crosses in breeding programs. The objective of this study was to describe the morphological patterns and viability of pollen grains from five accessions of Passiflora edulis f.

STUDIES ON JOJOBA [Simmondsia chinensis (LINK) SCHNEIDER] ~ 111- POLLEN VIABILITY AND POLLEN ULTRASTRUCTURE. [PDF]
Journal of Plant Production, 2004 Fresh pollen of jojoba attained the highest pollen viability at the beginning of the flowering season, where pollen fertility percentages for all the tested male parents exceeded 90%.

Chloride fluxes in lily pollen tubes: a critical reevaluation
, 2004 Microelectrodes, made from a Cl?-selective liquid ion exchanger previously used to measure putative Cl- fluxes in Lilium longiflorum pollen tubes, were characterized. The electrodes were poorly selective, possessing only about 10-fold selectivity for Cl?

Success of coastal sage scrub restoration is influenced by local adaptations of shrub species
American Journal of Botany, EarlyView.Abstract Premise Restoring plant communities is increasingly challenging with climate change. While practitioners have traditionally used local seed sources, many are recommending assisted migration, possibly from more extreme environments such as inland rather than coastal environments, for restoration.

Biological Reviews, EarlyView.ABSTRACT During their long evolutionary history, land plants have evolved a range of adaptations to different abiotic stressors. These help explain present‐day diversity and distribution patterns, as well as the potential resilience of natural and agricultural systems to a changing climate. Most previous research has focused on adaptation to individual

Gelechiidae Moths Are Capable of Chemically Dissolving the Pollen of Their Host Plants [PDF]
, 2011 Background: Many insects feed on pollen surface lipids and contents accessible through the germination pores. Pollen walls, however, are not broken down because they consist of sporopollenin and are highly resistant to physical and enzymatic damage. Here
