Growth of Some Ornamental Eucalyptus Species During Nursery Stage

Abstract

Eight Eucalyptus species (1 and 2 years old) were tested at the Faculty of Agriculture. Tripoli, during the period 1977-1979. The species tested included: E. caesia; E. preissiana; E. leucoxylon; E. cinerea: E. kitsoniana; E. strucklandii: and E. erythrocorys, which were newly introduced from Australia; and E. camaldulensis, a commonly planted species in Libya. Plants of E. camaldulensis of 2 years old. had produced the longest stem (239.00 cm). the largest stem diameter (15.13 mm). a greater number of leaves (170.00), and the longest leaves (19.08 cm) of all Eucalyptus species under evaluation. On the other hand, E. cinerea had developed short plants (46.75 cm) with small stem diameter (3.83 mm) and great number (186.00) of small leaves (7.60cm2). Stem and leaf characteristics of the other six species were intermediate.
