Eucalypt limestone tolerance, growth and physiology, limestone stresses

What is it about?

The present research was implemented to analyse the seedling tolerance of three species Eucalyptus gomphocephala DC (Myrtaceae) (common name 'Tuart'), Eucalyptus marginata Sm

Why is it important?

The research presented in this paper focuses on the tolerance of three eucalypts species to soils enriched by natural limestone, as measured by changes in growth and physiology over 80 days.

). In this study limestone was added to the soil to determine how it might influence the growth and physiology of three local Perth eucalypt species. E. gomphocephala is restricted soils overlying limestone on Perth’s Swan Coastal Plain, and according to total seedling dry weight data and calculated relative growth rates was the most tolerant to the limestone-enriched soils. However, when examining all the growth and physiological data collected C. calophylla appears to be the most tolerant, with no significant difference in leaf allocation or leaf water loss between the well-watered controls and the limestone-enriched treatments. E. marginata was the least tolerant with a 14% reduction in stomatal conductance.
