Wood structure, xylem functionality and growth of six Salix clones in two sites with different environmental stress in Argentina
The aims of the study were to evaluate the effects of abiotic stress (plantation site) and genotype (clone) on the wood anatomy and density of six Salix (willow) clones at three ages (2, 7, and 12 years), and the impact of these effects on the theoretical xylem hydraulic conductivity (Ks) and grow...

| description | The aims of the study were to evaluate the effects of abiotic stress (plantation site) and genotype
(clone) on the wood anatomy and density of six Salix (willow) clones at three ages (2, 7, and 12 years),
and the impact of these effects on the theoretical xylem hydraulic conductivity (Ks) and growth. The clones
studied were ´Ragonese 131-25 INTA´, ´Ragonese 131-27 INTA´ and “250-33” (originated from crosses between
Salix babylonica and S. alba), ´Barrett 13-44 INTA´ and “NZ 26992” (originated from crosses between S.
matsudana and S. alba), and the clone S. babylonica var. sacramenta ´Soveny Americano´. They were planted
in two sites of the province of Buenos Aires, Argentina, with different abiotic stress: i) the Paraná River
Delta, a site with recurrent floods, and ii) a continental site with lower water availability and no floods. The
vessel morphometry, wood density, Ks, and current annual increments at the three ages were determined.
The clone x site interaction was the source of variation with greatest impact, being this significant for vessel
diameter, Ks, wood density and growth. This means that, depending on the type of stress at the plantation
site, the clones responded differently, showing differences in their structure, functionality, and wood production.
The results showed that the clones Soveny Americano and 26992 were better suited to stress by flood, whereas
clones 131-25, 131-27, 250-33 and 13-44 were better adapted to moderate drought conditions, with responses
at the level of the xylem and wood density, and therefore at the level of wood production. |

Os objetivos do trabalho foram: 1- determinar o efeito do estresse hídrico (sítios de implantação) e do genótipo (clone) na anatomia e densidade da madeira produzida em seis clones de salgueiros em três idades; 2- verificar como essas variações na anatomia impactam na condutividade hidráulica teórica do xilema (Ks) e no crescimento. Foram mostrados seis clones, de 13 anos de idade de origem do cruzamento Salix babylonica x S. alba (Ragonese INTA 131-25, 131-27 e 250-33), S. matsudana x S. alba (Barrett 13-44 e NZ 26992) e S. babylonica var sacramenta ´Soveny Americano´ implantados em duas situações com diferente estresse abiótico (sítio DM Delta Del Río Paraná com inundações recorrentes e sítio LH zona continental província de Buenos Aires, com menor disponibilidade da água e sem inundações). Foi determinado: morfometria dos vasos, densidade da madeira, Ks e incrementos correntes anuais em três idades (2, 7 e 12 anos). A interação clone x sítio foi a fonte de variação que maior impacto teve nas variáveis e foi significante para o diâmetro de vasos, densidade, Ks e crescimentos. Isso significa que dependendo do tipo de estresse sofrido no sítio de implantação, os clones respondem de maneira diferente em sua estrutura, funcionalidade e produção da madeira. Existem clones melhor adaptados ao estresse por inundação (americano e 26992) e outros mais adaptados nas condições moderadas de seca (131-25, 131-27, 250-33 e 13-44), obtendo respostas no nível do xilema, densidade e, portanto, a produção da madeira.
