Agent-Based Modeling of Pollen Competition [PDF]
, 2018 Non-random mating in Arabidopsis Thaliana is, at least in part, due to intense competition between pollen grains to fertilize the limited number of ovules.

Toward in vitro fertilization in Brachiaria spp. [PDF]
, 2010 Brachiaria are forage grasses widely cultivated in tropical areas. In vitro pollination was applied to accessions of Brachiaria spp. by placing pollen of non-dehiscent anthers on a solid medium near isolated ovaries.

Stimulation of Nicotiana tabacum pollen tube growth by γ-irradiation [PDF]
, 1989 Irradiation of pollen grains from Nicotiana tabacum with 60Co-γ-irradiation in the dose range of 1–6Gy stimulates growth of the pollen tube up to 50% above control level.

Pollen biology and hormesis: Pollen germination and pollen tube elongation
Science of The Total Environment, 2021 This paper evaluated the occurrence of hormetic dose responses in pollen reported over the past eight decades. Hormetic doses responses were induced by a wide range of chemical and physical agents in 34 plant species for pollen germination and pollen tube growth/elongation.

Regulation of pollen tube growth [PDF]
Acta Botanica Neerlandica, 1995 Most textbooks describe pollen and pollen tubes as the vectors carrying the male sperm cells in seed plants. The pollen tubes grow through the style to the ovule, where the sperm cells are delivered to the egg cells in the embryo sacs. Pollen tubes always grow in an alien environment: in evolutionary terms they derive from the haustorium through which ...

Effects of post-translational modifications catalysed by pollen transglutaminase on the functional properties of microtubules and actin filaments [PDF]
, 2009 TGases (transglutaminases) are a class of calcium-dependent enzymes that catalyse the interactions between acyl acceptor glutamyl residues and amine donors, potentially making crosslinks between proteins.

Pollen tube growth and the pollen-tube pathway of Nymphaea odorata (Nymphaeaceae) [PDF]
Botanical Journal of the Linnean Society, 2010 An important aspect of the evolution of carpel closure, or angiospermy, is the relationship between pollen tube growth patterns and internalization of the pollen-tube pathway. True carpel closure, involving postgenital fusion of inner carpel margins, is inferred to have arisen once within the ancient order Nymphaeales, in the common ancestor of ...

Determination of cardinal temperatures for sugar apple ( Annona squamosa L.)
Ciência e Agrotecnologia, 2016 The sugar apple is highly dependent on the pollination and fruit tree pollen performance is crucial for successful fertilization and fruit set. The objective of this study was to determine the cardinal temperatures for in vitro pollen grains germination ...

Effect of boron on directionality of pollen tube growth in Petunia and Agapanthus [PDF]
, 1990 The effect of boron on pollen tube growth was tested using Petunia Juss. styles and the semivivo technique, while Agapanthus L’Hérit. pollen was used for in vitro germination experiments.
