Pollen Germination and Pollen Tube Growth in Gymnosperms. [PDF]
Plants (Basel), 2021 Pollen germination and pollen tube growth are common to all seed plants, but these processes first developed in gymnosperms and still serve for their successful sexual reproduction. The main body of data on the reproductive physiology, however, was obtained on flowering plants, and one should be careful to extrapolate the discovered patterns to ...

Effect of temperature on pollen germination for several Rosaceae species: influence of freezing conservation time on germination patterns [PDF]
PeerJ, 2019 Between February 2018 and April 2018, flowers were collected from eight Rosaceae species. Flowers were kept in a freezer at −20 °C for three freezing times (Treatment 1, two months; Treatment 2, four months; Treatment 3, six months).

Differential effects of low and high temperature stress on pollen germination and tube length of mango (Mangifera indica L.) genotypes. [PDF]
Sci Rep, 2023 Mango flowering is highly sensitive to temperature changes. In this research, the maximum values of pollen germination rate (PGR), pollen tube length (PTL) and their cardinal temperatures (Tmin, Topt and Tmax) were estimated by using quadratic equation ...

Secretory Vesicles Targeted to Plasma Membrane During Pollen Germination and Tube Growth. [PDF]
Front Cell Dev Biol, 2020 Pollen germination and pollen tube growth are important biological events in the sexual reproduction of higher plants, during which a large number of vesicle trafficking and membrane fusion events occur.

Osmosensor-mediated control of Ca2+ spiking in pollen germination. [PDF]
NatureHigher plants survive terrestrial water deficiency and fluctuation by arresting cellular activities (dehydration) and resuscitating processes (rehydration). However, how plants monitor water availability during rehydration is unknown.

Lipid Composition and Associated Gene Expression Patterns during Pollen Germination and Pollen Tube Growth in Olive (Olea europaea L.). [PDF]
Plant Cell Physiol, 2020 Pollen lipids are essential for sexual reproduction, but our current knowledge regarding lipid dynamics in growing pollen tubes is still very scarce. Here, we report unique lipid composition and associated gene expression patterns during olive pollen ...

Effect of sulfur on pollen germination of Clemenules mandarin and Nova tangelo [PDF]
PeerJ, 2023 This study aims to elucidate whether sulfur can inhibit citrus pollination by affecting pollen grains. For this, four sulfur-based products (inorganic sulfur, water dispersible granular sulfur, ammonium sulfate, copper sulfate) were tested to evaluate ...
