“Portrayals” of long-lived Mediterranean plants linked to virtues

“…It is noteworthy that the classical name styrax has been related with two Mediterranean species, i.e. the shrub Styrax officinalis and the endangered tree Liquidambar orientalis (Diapoulis 1952;Thomas 1961;Yaltırık & Efe 2000); also, there are linguistic, botanical and chemical confusions concerning the balsamic resin styrax (Howes 1950;Thomas 1961;Modugno et al 2006). Cultivated and wild olive trees (Olea europaea), elements of the civilisation that was formed around the Mediterranean Sea, played a vital role in human life and symbolised charity (Rhizopoulou 2004;Kaniewski et al 2012).…”

Effects of water stress on photosynthesis and respiration of two populations of sweetgum ...

“…Throughout its range in the United States, sweetgum attains its best growth and is most important as a part of the vegetation on moist bottomland sites, although it will grow on dryer uplands (Chittenden, 1906;Oosting, 1942;Thomas, 1961).…”

“…The root system varies from very shallow with no taproot in swamp situations, to a very deep taproot on dry hillsides (Chittenden, 1906;Trenk, 1929;Thomas, 1961). Roberds (1965), in a study of variation in sweetgum seedlings from several areas throughout North Carolina, found differences between sources in corkiness of the bark, which could be correlated with the May-August precipitation of the source area, and in time of leaf abscission, correlated with the annual temperature, frost free season, and longitude of the source.…”
