A proposed methodology for the determination of seed sources for tree native species based on environmental variables: the case of Quillaja saponaria Mol
(2024)There is an increasing interest in planting native tree species for commercialization and restoration purposes. However, the seed provenance zones of plant material to complete these activities successfully are not always ...

Balance energético en el primer ciclo de corta de tres especies de eucalipto con diferentes niveles de manejo en el secano mediterráneo de Chile central
(2019)El Secano Mediterráneo de Chile central es una zona afectada por altas tasas de erosión y un clima muy fluctuante, con largos períodos de bajas precipitaciones, los que limita su productividad. Una alternativa para esta ...

Changes in drought tolerance of Pinus radiata in Chile associated with provenance and breeding generation
(2016)Key messageIn Chile, breeding radiata pine for growth has led to drifts in the degree of drought tolerance of the seedlings. Interior provenances gained a larger tolerance to drought after three breeding generations as ...

Differential adaptations in nursery seedlings from diverse Chilean provenances of Peumus boldus Mol.
(2016)Seed germination, seedling growth and biomass allocation of the endemic species Peumus boldus Mol. (Boldo) were studied in four provenances (two northern and two southern provenances) from central Chile. Seeds collected ...

Douglas-fir exhibits high growth performance and survival in southern Chile
(2023)We evaluated the potential of 19 provenances of the coastal variety of Douglas-fir for commercial plantation development in Southern Chile. Seedlings from 668 families were planted in two trials differing in site preparation ...

Early growth and physiological acclimation to shade and water restriction of seven sclerophyllous species of the mediterranean forests of central Chile
(2024)The success of using active restoration in Mediterranean-type climate zones mostly depends on an appropriate matching of plant species and specific management prescriptions upon establishment. In this study, we assessed ...

Effect of crop management intensity on energy and carbon dioxide balance of two bioenergy Sorghum bicolor hybrids
(2019)Although bioenergy sorghum has many traits that make it ideal for biofuel production, management conditions that can affect the productivity and sustainability of these systems are still poorly understood. This paper ...

Effect of the soil matric potential on the germination capacity of prosopis chilensis, quillaja saponaria and cryptocarya alba from contrasting geographical origins
(2022)As a consequence of the megadrought in Central Chile, it is expected that most of the distribution of woody species will be narrowed in the northern limits because of restrictions imposed by soil matric potential on seed ...
-
Field performance of various Pinus radiata breeding families established on a drought-prone site in central Chile
(2017)Background: Pinus radiata D.Don is in its third generation of selective breeding on contrasting site types in central Chile, creating interest in its responses to selection and any differential adaptation to site types. ...
-
First report on precocious flowering in 5-month-old Peumus boldus Mol. seedlings
(2023)Whereas Peumus boldus Mol. rarely !owers in its native habitat until at least 4 years old, in this article, we report the precocious !owering of 5-month-old P. boldus seedlings and provide possible explanations for this ...

Genetic control of growth, biomass allocation, and survival under drought stress in Pinus radiata D. Don seedlings
(2014)Drought is one of the critical factors limiting plant growth, and knowledge about genetic adaptation to drought is necessary to develop strategies for successful reforestation on drought-prone sites. In this study, genetic ...

Gestión de riesgo como herramienta para la conservación de los bosques de nothofagus alessandrii, una especie en peligro de extinción de Chile central
(2018)El cambio climático es una amenaza global que está afectando diversas formaciones boscosas, con la consiguiente pérdida de servicios ecosistémicos y perjuicio en la calidad de vida de los habitantes. Ante la presencia ...
-
Growth and biomass partitioning of nine provenances of Quillaja saponaria seedlings to water stress
(2019)Information on the morphological and physiological responses of seedlings to stressors, such as water stress, is required for successful early establishment of seedlings. We examined provenance variation in morphological ...
-
Growth of provenances of cryptocarya alba during water stress and after re–watering in the nursery
(2021)Intensification of drought in Mediterranean–type climates has limited seedling establishment. The knowledge of the ecology of selected species and its intraspecific variation to water stress at the seedling stage should ...
-
Growth of radiata pine families in nursery and two years after field establishment
(2020)Pinus radiata D. Don is the most widely planted exotic species in Australia, Chile, New Zealand and Spain. In this study, growth and survival of P. radiata were compared in 30 open pollinated families grown under two ...

Influence of provenance origin on the early performance of two sclerophyllous Mediterranean species established in burned drylands
; ; ; Carrasco-Benavides, Marcos
; ; ; (2021)
Forest restoration have had limited success due to intense and prolonged droughts in Mediterranean-type ecosystems. In this context, knowledge of growth and physiology in seedlings of different provenances can be useful ...

Interactive effects of water stress, container size and fertilizer on survival, gas exchange and morphological traits of Quillaja saponaria seedlings
(2017)Quillaja saponaria es una especie nativa del bosque nativo chileno valiosa por sus cualidades económicas y ecológicas y que ha sufrido una importante degradación a lo largo del país; sin embargo, la determinación de las ...
-
Outplanting performance of three provenances of Quillaja saponaria Mol. established in a mediterranean drought-prone site and grown in different container size
(2020)In degraded environments with restricted seed availability, like those burned by wildfires in central Chile during 2017, the use of plant material from outside its area of origin for restoration purposes needs to be ...

Provenance influences seed germination and phenotypic responses to water restriction in the endemic Beilschmiedia miersii (Gay) Kosterm
(2023)The higher drought intensity recorded in the last decades in the Mediterranean zone of Chile increased the level of threats of the endemic Beilschmiedia miersii (Gay) Kosterm and has raised concern about its capacity to ...
