We aimed to quantify frost tolerance and damage on Eucalyptus pilularis provenances and progenies in Curitibanos, Santa Catarina State, Brazil. Mortality and severity of damage were assessed before frost at 7 months old and at 14 and 19 months old after frost events. Frost resulted in plant mortalityof 55.7%, with no difference among progenies and provenances. The tolerance of 5.3% may have occurred due to spec...

No. of bitstreams: 0 Previous issue date: 2017-12-01; Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP); Background and aims: While the role of deep roots in major ecosystem services has been shown for tropical forests, there have been few direct measurements of fine root dynamics at depths of more than 2 m. The factors influencing root phenolo...
