Pollen Germination in Some Gramineae

Germination of Barley Pollen

The artificial germination of plant pollens has met with varying success. As a whole, the pollen of the Gramineae has proved very difficult to germinate. While experiments with the pollen of many plants have resulted not only in ready germination but in satisfactory methods of preserving the pollen for considerable periods of time, the results with many of the Gramineae have been far from satis...

A Contribution to the Pollen Morphology of Family Gramineae

Pollen morphology of 20 species belonging to the 14 genera of the family Gramineae has been investigated using light microscope and scanning microscope. It is a stenopalynous in nature. Pollen grains mostly spheroidal, monoporate rarely diporate, ±circular, pores small operculate, non-operculate, annulate or non-annulate. Tectum areolate to scabrate. On the basis of exine ornamentations 5 disti...

In Vitro Pollen Germination - A Review

Pollen is a unique plant tissue that potentially can be used and manipulated to the advantage of the geneticist, breeder, physiologist, or germplasm curator. Since pollen of most species is haploid and each cell is independent, pollen has the potential to provide a microbial-like system for evaluation, assay, and selection. Whatever the interest and use, the viability of the pollen is necessary...

In Vitro Germination of Avocado Pollen

Abstract. Avocado pollen was germinated in vitro without recourse to germination on the style. The technique employed involved inclusion of pollen grains in liquid medium of 15% sucrose and minerals and application of 1 or 2 drops on 1% agar plus 15% sucrose and minerals. No germination was obtained on agar plus sucrose without placement of pollen in liquid first. Of the cultivars tested, 'Etti...
