Wood Development

This study performed a pilot evaluation of the wood quality—defined by a single parameter: dynamic modulus of elasticity (MOEdyn, N mm−2)—of small-leaved lime (Tilia cordata Mill.) trees in urban areas. A search of the literature revealed few studies which examined the specifics of tree wood development in urban areas. Little is known about the potential of wood from urban trees wood of their suitability for the timber industry. In this study, an acoustic velocity measuring system was used for wood quality assessment of small-leaved lime trees. The MOEdyn parameter was evaluated for small-leaved lime trees growing in two urban locations (along the streets, and in an urban park), with an additional sample of forest sites taken as the control. MOEdyn was also assessed for small-leaved lime trees visually assigned to different health classes. The obtained mean values of MOEdyn of 90–120-year old small-leaved lime trees in urban areas ranged between 2492.2 and 2715.8 N mm−2. For younger trees, the values of MOEdyn were lower in the urban areas than in the forest site. Otherwise, the results of the study showed that the small-leaved lime wood samples were of relatively good quality, even if the tree was classified as moderately damaged (which could cause a potential risk to the community). Two alternatives for urban tree management can be envisaged: (1) old trees could be left to grow to maintain the sustainability of an urban area until their natural death, or (2) the wood from selected moderately damaged trees could be used to create wood products, ensuring long-term carbon retention.

Vegetation research on the lava flows of the historic volcanic eruption of 1705 in Arafo, Tenerife, Canary Islands, is presented. The study area located in the 830000-year-old valley of Güímar was created after a massive landslide 47 km3 in volume. The research is divided into three parts, which cover an altitudinal range from around 35 to 1583 m a.s.l. from the Lower-semiarid Inframediterranean up to the Lower-dry lower-Mesomediterranean bioclimatic belts. First, a phytosociological study of the vegetation present in the area was made and concluded that richness in pioneer communities form a vegetation complex with a high degree of endemicity. Two new associations and four pioneer communities are proposed. Especially notable are the communities of Stereocauletum vesuviani and the pioneer communities of Pinus canariensis. The second part of the research was a field sampling study of 450 individuals of Pinus canariensis, which were measured at different altitudes to obtain data about the colonization dynamics of this species on this 300 years old substrate. We found that stem diameter seems to be a good indicator for healthy tree development at a range between 700 to 1300 m asl, which corresponds to the pine forest as potential vegetation and that many individuals show signs of nutrient deficiency. The third part consists of the publication of two new populations of the Canarian endemism Himantoglossum metlesicsianum, a highly endangered orchid. The monitoring of these two populations has recently begun, and further research will be conducted on all three aspects of this publication, which will be presented and expanded upon in the future.

Aim of the study: To develop an efficient method to regenerate plants through somatic embryogenesis of an ecologically relevant tree species such as Pinus canariensis.Area of study: The study was conducted in the research laboratories of Neiker-Tecnalia (Arkaute, Spain).Material and methods: Green cones of Pinus canariensis from two collection dates were processed and the resulting immature zygotic embryos were cultured on three basal media. The initiated embryogenic tissues were proliferated testing two subculture frequencies, and the obtained embryogenic cell lines were subjected to maturation. Germination of the produced somatic embryos was conducted and acclimatization was carried out in a greenhouse under controlled conditions.Main results: Actively proliferating embryogenic cell lines were obtained and well-formed somatic embryos that successfully germinated were acclimatized in the greenhouse showing a proper growth.Research highlights: This is the first report on Pinus canariensis somatic embryogenesis, opening the way for a powerful biotechnological tool for both research purposes and massive vegetative propagation of this species.Keywords: acclimatization; Canary Island pine; micropropagation; embryogenic tissue; somatic embryo.Abbreviations used: embryogenic tissue (ET); established cell line (ECL);  somatic embryogenesis (SE); somatic embryos (Se’s).
