Changes in drought tolerance of Pinus radiata in Chile associated with provenance and breeding generation
Espinoza-Meza, Sergio; Magni, Carlos R.; Santelices-Moya, Rómulo; Ivković, Miloš; Cabrera-Ariza, Antonio (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.
Espinoza-Meza, Sergio; Santelices-Moya, Rómulo; Cabrera-Ariza, Antonio; Magni, Carlos R.; Garrido, Emilio F. (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 ...

Genetic control of growth, biomass allocation, and survival under drought stress in Pinus radiata D. Don seedlings
Espinoza-Meza, Sergio; Martínez, Víctor A.; Magni, Carlos R.; Ivković, Miloš; Santelices-Moya, Rómulo; Guerra, Fernando P.; Cabrera-Ariza, Antonio (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 ...

Growth of radiata pine families in nursery and two years after field establishment
Espinoza-Meza, Sergio; Ivković, Miloš; Yáñez, Marco; Magni, Carlos R.; Santelices-Moya, Rómulo; Cabrera-Ariza, Antonio (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 ...
