Tuzlu Koşullarda Mikoriza Uygulamalarının Cupressus arizonica "Glauca" (Mavi Servi) Çeşidinde Bitki Gelişimi ve Bazı Stres Parametreleri Üzerine Etkisi

Abstract At present, in the New World, C. arizonica and its varieties are of low economic importance, but they are sometimes cut for fenceposts, fuelwood and lumber, and recently they have become popular as Christmas trees. By contrast, the Arizona cypress (C. arizonica var. arizonica) and the smooth cypress (C. arizonica var. glabra) are widespread in Europe and are used for landscaping, erosion control, windbreaks, and to a minor extent for lumber.

Cupressus Arizonica

In this study, the post-fire regeneration of three coniferous species (Pinus brutia, Cupressus sempervirens and Cupressus arizonica) was examined in the peri-urban forest of Thessaloniki, Northern Greece. The wildfire took place in July 1997 and burned almost 60% of the forest vegetation. During the autumn of 2010, 34 experimental plots were established in all aspects within the burned area. In each experimental plot the following measurements were carried out: height, diameter at breast height and crown projection in two perpendicular diameters. The results show that the Pinus brutia individuals, most of which came from natural regeneration, presented the best growth, in relation to the two other species in all aspects. As for Cupressus sempervirens, equal parts of which came from natural and artificial regeneration was characterized by remarkable growth especially in the Northeastern aspect. Finally, Cupressus arizonica existed in all aspects except the Northeastern. It also presented a satisfactory development, especially on the Southern aspect. Fourteen years after the fire pure or mixed stands of the above mentioned species show vigorous growth and good stem quality. Finally, the rates of participation of individual forest species indicate that the restoration has been achieved mainly by natural regeneration.

Cupressus Arizonica

Abstract Rooted stem cuttings of ‘Carolina Sapphire’ smooth Arizona cypress [Cupressus arizonica var. glabra (Sudw.) Little ‘Carolina Sapphire’] grown in calcined clay in 3.8 liter (#1) containers were fertilized daily for 16 weeks with a complete nutrient solution containing 0, 20, 40, 80 or 160 mg N/liter supplied as ammonium nitrate. Plant heights and stem diameters were unaffected by N rate suggesting that a daily nutrient application of 20 mg N/liter was adequate for maximizing growth. Nitrogen fertilization increased heights and stem diameters by 71% and 56%, respectively, compared to the nontreated controls (0 mg N/liter). Even though shoot growth was unaffected by increasing N levels, foliage N concentration was positively correlated (r = 0.75, P < 0.0001) to N levels. As N concentration increased, total root area and total root length increased quadratically. Nitrogen fertilization increased root area and root length 119% and 108%, respectively, compared to the nontreated controls. Phosphorus concentration of shoots increased quadratically with increasing N levels. Nitrogen rate failed to affect K concentration of shoots. Shoot Ca and Mg concentrations decreased with increasing N levels.
