Figures & Tables

The experimental design. FWC – field water capacity, chlorophyll content (mg·cm−2), RWC – relative water content (%), SLA – specific leaf area (cm2·g−1), LA – leaf area (cm2), root volume (cm3), shoot length (cm), stem and root dry mass (%)

Evolution of the chlorophyll content in the leaves of stressed and control Ginkgo biloba L. plants under different irrigation regimes, expressed in milligrams per square meter. The numbers 0–6 represent data collected at 2-week intervals (from the first of June to the seventh of September)

Relative water content (RWC) in the leaves of stressed and control Ginkgo biloba plants under conditions of water stress. Numbers 0–6 represent data collected at 2-week intervals (from the first of June to the seventh of September)

Leaf area (LA) of the top five ginkgo leaves from the stressed plant (S) and from the controlled plant (C) (software image J used)

LSD test for statistical significance of differences in the magnitude of mean values of stem dry mass (%), root dry mass (%), root volume (cm3) and shoot length (cm) of Ginkgo biloba plants under water stress
