The Cytoskeleton of Pollen Grains and Pollen Tubes

1992
The cytoskeleton is assumed to be involved in many internal functions of the eukaryotic cell, e.g. organelle movement, mitotic and meiotic division, cell morphogenesis and cell growth (Dustin, 1984; Bershadsky and Vasiliev, 1988). Examination of a broad variaty of mono- and dicotyledones has revealed the presence of microtubules and/or actin filaments ...

Pollen Tube Growth in vivo as a Measure of Pollen Viability

Science, 1962
Observation by fluorescence of tomato pollen tubes in fixed styles clearly showed that all pollen samples grew regardless of age and fruit or seed setting potential. Methods commonly used to evaluate pollen viability, such as staining and germination, may predict growth in the style but do not always predict seed setting ability.

Pollen Germination and Pollen-Tube Growth

1987
Publisher Summary Pollen germination and pollen-tube growth events when viewed either in culture or in the style are considered as biochemically, physiologically, and structurally complex. The various processes involved are each independent in some measure, but still all are interactive—namely, the successful attainment of the delivery of two male ...

Pollen Tube Chemotropism

1973
The pollen tube of flowering plants may grow through as much as 50 cm of the stylar tissue, enter the micropyle of an ovule and then discharge from its tip two non-motile sperm cells in the immediate vicinity of an unfertilized egg. This review is concerned with the factors that direct the pollen tube to the egg.
