An Optimum Design For Seedling Seed Orchards To Maximize Genetic Gain: An Investigation On Seedling Seed Orchards Of Eucalyptus pellita F. Muell

Seed orchards in development.

This paper reviews the role of seed orchards as output systems for genetic improvement programs. In this paper, technological changes since the 1950s are examined, with emphasis on recent developments. The need to equate the type of seed orchard to the type of forestry practiced is recognized, as is the significance of the relationship between seed orchards and other output systems for genetica...

Flowering Phenology in Teak Seed Orchards – Genetic Variation, Measurement and Implications to Seed Orchard Fertility

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...

Selection of SSR markers for population studies in Eucalyptus globulus seed orchards

Background Eucalyptus globulus is a widely planted species in temperate regions of the world for pulpwood production. Its good characteristics for kraft pulping in addition to a broad adaptability to different site conditions have led this species to be employed in commercial plantations and to be included in breeding programs [1]. Uruguay has approximately 300.000 hectares forested with E. glo...

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...
