As the result of intensive research and breeding efforts over the last 20 years, the yield
potential and yield quality of cereals have been greatly improved. Nowadays, yield safety …

To reproduce, higher plants utilize a unique multicellular microorganism: the male
gametophyte, or pollen grain. The independent lifetime of flowering plant gametophytes is …

The author offers an overview of pollen biology and biotechnology for students and
researchers in areas such as reproductive biology, biotechnology, aeropalynology, plant …

Studies in corn have identified genetic variation attributable to unitary factors at perhaps
1000 or more loci, loosely defined; if rigorous criteria were applied with regard to supporting …

In maize (Zea mays L.) large decreases in kernel number result when low water potentials
(Ψ w) and high temperatures occur during pollination. To gain insight into the basis for the …

Controlling pollination is necessary to ensure maximum kernel set and high levels of genetic
purity in maize. Current approaches for measuring maize pollen production are fairly simple …

The ongoing discussion on the co-existence between genetically modified (GM) and non-
GM crops becomes more important in the European Union (EU). With the recent inscription …

There is an increasing concern about the preservation of genetic identity of conventional
maize (Zea mays L.) and of distance required to segregate non‐genetically modified (non …

Pollen from 13 species of gymnosperms and angiosperms was studied for soluble and
insoluble carbohydrates at dispersal. Starch reserves stored during pollen development give …

Two pollen species from the Gramineae family were investigated as to their differential
sensitivity to desiccation. Germination in vivo ceased to occur after previous drying to 7–8 …
