The effects of the parent environment on seed germinability
TLDR
Lower dormancy (i.e., increased germinability) is generally associated with the following environmental conditions during seed development: high temperatures, short days, red light, drought and high nitrogen levels.Abstract:
The growing conditions of a parent plant may affect the degree of dormancy of its seeds. This has been demonstrated in numerous species, both wild and cultivated. The evidence comes from field observations and controlled experiments. A survey of the literature shows that some well defined patterns emerge, with certain environmental factors tending to have similar effects over a wide range of species. Lower dormancy (i.e., increased germinability) is generally associated with the following environmental conditions during seed development: high temperatures, short days, red light, drought and high nitrogen levels. The effects are probably the result of changes in the quantity, mobility or activity of growth substances such as abscisic acid. The ecological implications of the phenomenon are briefly discussed.read more

TL;DR: This work has shown clear trends in the dispersal and regeneration of seeds in disturbed areas, and these trends are likely to continue into the next decade.

Plant reproduction under elevated CO2 conditions: a meta-analysis of reports on 79 crop and wild species
TL;DR: Crops were more responsive to elevated CO 2 than were wild species and these differences and the substantial decline in seed [N] in many species have broad implications for the functioning of future natural and agro-ecosystems.

Seed vigour and crop establishment: extending performance beyond adaptation
TL;DR: How some seed characteristics that serve as adaptive responses to the natural environment are not suitable for agriculture are discussed and ways in which basic plant science could be applied to enhance seed performance in crop production are discussed.

Completing the cycle: maternal effects as the missing link in plant life histories
TL;DR: Patterns of gene expression and protein synthesis in seeds indicate that the maternal genotype has the opportunity to influence its progeny's germination behaviour, which is relevant for understanding the variation in plant life cycles.

TL;DR: It is shown that when an individual dies, it may or may not be replaced by an individual of the same species, which is all‐important to the argument presented.

Maternal effects in plants

TL;DR: It is contention that despite evidence that maternal effects can have a large in fluence on offspring phenotype, few detailed studies have identified the specific causes of maternal effects, particularly in natural populations.
