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 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

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 ...

Observations and modelling of birch pollen emission and dispersion from an isolated source [PDF]
, 2014 The occurrence of allergic diseases in western countries increased during the last decades due to greater awareness towards a hygienic lifestyle. The hygiene hypothesis relates the reduced expo- sure to microbial pollution to an underdevelopment of the

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 ...
