“…Site characteristics were presented elsewhere (Codesido 2006;Codesido and Fernández-López 2009). Daneiro and Monte Xalo have Atlantic climate characterized by relative high annual precipitation (mean annual precipitation: 1,776 and 1,200 mm for Daneiro and Monte Xalo, respectively) and low summer drought.…”

Juvenile–mature genetic correlations in Pinus radiata D. Don. under different nutrient × water regimes in Spain

Individual and family heritabilities and juvenile-mature genetic correlations were estimated for growth and biomass traits recorded in treatment with optimal and limiting water and/or nutrient availability to study how the different growth environments affected genetic parameter estimates. Thirty open-pollinated families, randomly selected among the 58 families used in field progeny tests in Galicia, were cultivated for 30 weeks in a climatic chamber under controlled conditions. Two water regimes (high and low water supply) combined with two nutrient regimes (high and low nutrient supply) were applied by subirrigation. Several growth, branching and dry mass traits were assessed 30 weeks after sowing and compared with field performance (height, diameter and volume) of 4-year-old progeny tests established at three different sites in Galicia (NW Spain). Both the irrigation and the fertilization treatments had a strong effect in all the assessed traits except irrigation for the number of branches. Heritabilities for growth and biomass traits were moderate to high (0.13-0.77) in individual treatments. However, when analyzing all treatments together, the impact of the family 9 treatment interactions led to a reduction (0.20-0.35) in the heritability estimates. The results indicated that the genotype 9 water and genotype 9 nutrient interactions may be important and could not be ignored in the Galician radiata pine breeding program. Climatic chamber-field correlations were different between different traits measured at climatic chamber experiments and the three field tests. The correlations were larger with the wellwatered treatments, suggesting that further development of early testing methods for radiata pine in Galicia should include treatments with no limiting water availability.

“…Its fast growth has stimulated an exhaustive study of its wood production and a heavy requirement for developing breeding programs (Espinel et al, 1995;Codesido and Fernández-López, 2009). However, keeping in mind the future climate change scenario, the survival is still considered one of the main bottleneck processes for forest productivity.…”

“…Lammas shoots can have positive effects on trees as they increase the leaf area and thus photosynthetic capacity, and significantly add to the height growth in some tree species (Kozlowski 1964; Cline and Harrington 2007; Codesido and Fernandez-Lopez 2009). After defoliation due to herbivory or late spring frosts the ability for multiple flushing is of great advantage (Jones 1959; Cline and Harrington 2007).…”

“…However, other terms like ‘Johannis shoots’ (Kobel 1954; Lyr et al 1967; Weinreich 2000) or ‘summer flushes’ (Sabatier and Barthélémy 2001) are also used and in some species, even more than two flushes per growing season can occur (Jones 1959; Barthélémy and Caraglio 2007; Cline and Harrington 2007; for a critical revision of terms also see Caraglio and Barthélémy 1997). The occurrence of lammas shoots is most probably endogenously controlled, but also depends strongly on environmental conditions, such as water and nutrient supply during the growing season (Kobel 1954; Jones 1959; Kozlowski 1964; Simak 1970; Kolb and Matyssek 2001; Kozlowski and Pallardy 2002; Codesido and Fernandez-Lopez 2009). …”

Lammas shoots are flushes formed by some woody species later in the growing season. Having less time to develop, tissue formation is suggested to be incomplete leading to a higher peridermal water loss during consecutive months. In this study, we analysed morphological and anatomical parameters, peridermal conductance to water vapour and the level of native embolism in mid-winter and late-winter of lammas shoots and normal spring shoots of the apple varieties Malus domestica ‘Gala’ and ‘Nicoter’. Lammas shoots showed a significantly higher shoot cross-sectional area due to larger pith and corticular parenchyma areas. In contrast, phloem was significantly thicker in spring shoots. No pronounced differences were observed in xylem and collenchyma thickness or mean hydraulic conduit diameter. The phellem of spring shoots was composed of more suberinised cells compared to lammas shoots, which led to a significantly higher peridermal conductance in the latter. The amount of native embolism in mid-winter did not differ between shoot types, but in late-winter lammas shoots were more embolised than spring shoots. Data show that the restricted vegetation period of lammas shoots affects their development and, in consequence, their transpiration shield. This may also pose a risk for winter desiccation.
