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.

Pollen Germination and Pollen Tube Growth in Gymnosperms [PDF]
Plants, 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 ...

Pollen elicits proboscis extension but does not reinforce PER learning in honeybees [PDF]
, 2013 The function of pollen as a reward for foraging bees is little understood, though there is evidence to suggest that it can reinforce associations with visual and olfactory floral cues.

Biologia Plantarum, 2011 Mature pollen grain represents a highly desiccated structure with an extremely tough cell wall. Thanks to it, it resists common proteomic protocols. Instead, a robust homogenization has to be performed since proteins are needed to burst out of the cell ...

The rising tide of photographs: Not drowning but waving?
Captures, 2016 Concerns about the huge quantities of photographs circulating in digital networks have led some to proclaim that we are now drowning in images. This article surveys these anxieties by examining the work of artists who use photography’s scale, and ...

Understanding emissions of ammonia from buildings and the application of fertilizers: an example from Poland [PDF]
Biogeosciences, 2015 A Europe-wide dynamic ammonia (NH3) emissions model has been applied for one of the large agricultural countries in Europe, and its sensitivity on the distribution of emissions among different agricultural functions was analyzed by comparing with ...

Pollen Sporoplasts: Dissolution of Pollen Walls [PDF]
Plant Physiology, 1985 4-Methylmorpholine N-oxide monohydrate (MMNO.H(2)O), a potent solvent for polysaccharides, is an effective vehicle for release of membrane-enclosed male gametophytes (sporoplasts) from spore walls. This release occurs in minutes when pollen (Lilium longiflorum Thunb.) is suspended in a melt of MMNO.H(2)O at 75 degrees C. Continued heating at 75 degrees
