Pollen grain of barley (Hordeum vulgare L.) - pattern of development
Acta Societatis Botanicorum Poloniae, 2014 Pollen development in barley follows the general pattern established for other species of Poaceae: 1) microspore division occurs at the vacuolate microspore stage with polarly located nucleus; 2) microspore mitosis is immediately followed by phragmoplast

Inflated Sporopollenin Exine Capsules Obtained from Thin-Walled Pollen
Scientific Reports, 2016 AbstractSporopollenin is a physically robust and chemically resilient biopolymer that comprises the outermost layer of pollen walls and is the first line of defense against harsh environmental conditions. The unique physicochemical properties of sporopollenin increasingly motivate the extraction of sporopollenin exine capsules (SECs) from pollen walls ...

Pollen grain sporoderm and types of dispersal units
Acta Societatis Botanicorum Poloniae, 2014 The pollen of gymnosperms and angiosperms may be dispersed in monads, tetrads, polyads, massulae or compact pollinia. The monads and tetrads may form larger clumps of pollen because filiform pollen is tangled while other kinds of pollen can be glued by ...
