Seed mass versus seedling performance in Scots pine: a maternally dependent trait

Seed mass versus seedling performance in Scots pine: a maternally dependent trait

It is generally accepted that larger seeds give rise to seedlings with better performance. On the other hand, the size that a seed reaches is genetically determined by at least two different traits ; the genetic variability of the developing embryo and the genetic variability of the maternal plant. Thus, the relative contributions of these two traits affect seedling performance by influencing s...

Seed mass, seedling size and neotropical tree seedling establishment

1 We examined amongand within-species effects of seed mass for seedling establishment from seed to 5 years of age in a field experiment at Paracou, French Guiana. 2 Six seeds of each of eight species were weighed and planted into each of 120 plots (1 m 2 ) throughout closed-canopy forest along 12 100-m transects in 1998. 3 We described the microhabitat of each planting site using principal comp...

Influence of Seed Hydration on Seedling Performance

costs, field problems, and customer complaints, product and processing costs, and improvements in the marketplace. Questions that must be asked in such an analysis include: 1) Are sales being gained or lost due to quality? 2) Do our customers have to be “sold” on our products or do the products speak for themselves? Accountability analysis is examined by asking: 1) Are problems routinely identi...
