Water relations for two remote populations of Dracaena tree species from the dragon tree group, Dracaena cinnabari Balfour f. and Dracaena draco (L.) L., were studied to test our hypothesis that morphological and anatomical differences in leaf structure may lead to varied functional responses to changing environmental conditions. Sap flow measurements were performed using the heat field deformation method for four Dracaena seedlings grown in one glasshouse and two greenhouses, and leaf traits…

Long-term in situ sap flow monitoring in a mature Dracaena cinnabari tree on Socotra
TLDR
The ability to replenish succulent woody organs from atmospheric water and to survive long periods of drought from the internal supply distinguishes the behavior of this short-rooted arborescent monocot from the known strategies of deep-roOTS trees in arid areas.
Aerial Root Structure and Its Significance for Function in Dracaena draco
TLDR
It is observed that AR are similar to the lateral soil roots in terms of the distribution of the primary and secondary tissues.
Mechanisms underlying the long-term survival of the monocot Dracaena marginata under drought conditions
TLDR
The described anatomical features and physiological mechanisms impart D. marginata with high resistance to irregular watering and long-term water scarcity should help to improve predictions with respect to the impacts of droughts on this plant group.
Comparative leaf micromorphology and anatomy of the dragon tree group of Dracaena (Asparagaceae) and their taxonomic implications
TLDR
Micromorphological features of the leaf epidermis and the inner structure of leaf tissues of eight arborescent taxa of the genus Dracaena were analysed and can be used to identify the dragon tree group leaves, while the shape of epidermal cells and stomata types may be useful in the identification and classification of fragments of fossil leaves.
Sap Flow Measurements in a Socotra Dragon’s Blood Tree (Dracaena cinnabari) in its Area of Origin
TLDR
It is found that sap flow magnitude is low and of a similar range in all observed D. cinnabari species, and several methodological aspects detected from earlier observations of dicots which proved to be more pronounced in adult D. draco plant are presented.
Wettability, water absorption and water storage in rosette leaves of the dragon tree (Dracaena draco L.)
TLDR
Light is shed on the role of rosettes in water absorption by D. draco, and understanding of the functioning of this vulnerable species is broadened, because the mature leaves of the rosette are more wettable than the young ones.
Are Dracaena nebulophytes able to drink atmospheric water
Local Management System of Dragon’s Blood Tree (Dracaena cinnabari Balf. f.) Resin in Firmihin Forest, Socotra Island, Yemen
Various nontimber forest products (NTFPs) are produced from the forests and woodlands of Yemen. Dragon’s blood tree resin is one of the commercial NTFPs in Yemen and is produced by tapping Dracaena…
Growth dynamics of endemic Dracaena cinnabari Balf. f. of Socotra Island suggest essential elements for a conservation strategy
TLDR
For the dragon’s blood tree and likely for other taxa within this group, extremely slow growth and long generation times suggest that conservation and restoration efforts will require a commitment to active management that will last decades, rather than a short-term approach.
First Age-Estimation Model for Dracaena ombet and Dracaena draco subsp. caboverdeana
TLDR
The first model for crown age estimation was developed for Dracaena ombet Heuglin ex Kotschy and Peyr and for D. draco subsp.

Functional convergence in hydraulic architecture and water relations of tropical savanna trees: from leaf to whole plant.
TLDR
The patterns of water uptake and access to soil water during the dry season appeared to be the main determinant of wood density, which constrained evolutionary options related to plant water economy and hydraulic architecture, leading to functional convergence in the neotropical savanna trees studied.
Grasses of different C4 subtypes reveal leaf traits related to drought tolerance in their natural habitats: Changes in structure, water potential, and amino acid content.
TLDR
Three grasses of different C(4) subtypes, Paspalum dilatatum, Cynodon dactylon and Zoysia japonica, occur in natural habitats that differ in annual rainfall and are studied to identify traits related to drought tolerance.
Differences in morphological and physiological leaf characteristics between Tabebuia aurea and T. impetiginosa is related to their typical habitats of occurrence

Comparison of morphological and physiological traits between Tabebuia aurea (Silva Manso) Benth.
Sap flow and water use in African baobab (Adansonia digitata L.) seedlings in response to drought stress
Allocation to leaf area and sapwood area affects water relations of co-occurring savanna and forest trees
TLDR
Despite significant differences in water relations, relationships between traits such as wood density and minimum ΨL were indistinguishable for the two species groups, indicating that forest and savanna share a common axis of water-use strategies involving multiple traits.
Differentiation of water-related traits in terrestrial and epiphytic Cymbidium species
TLDR
Overall, epiphytic orchids exhibited substantial ecophysiological differentiations from terrestrial species, with the former type showing trait values indicative of greater drought tolerance and increased water storage capacity.
Crown age estimation of a monocotyledonous tree species Dracaena cinnabari using logistic regression
Unique woodlands of Dracaena cinnabari (DC) are at risk throughout most of their range (Socotra Island, Yemen) as a result of missing regeneration and overmaturity. Effective conservation measures…
Water relations of indigenous versus exotic tree species, growing at the same site in a tropical montane forest in southern Ethiopia
TLDR
Diurnal patterns of stem flux indicated that Croton, Eucalyptus and Podocarpus, in contrast to Cupressus, responded more directly to light than to atmospheric water pressure deficit, and at high VPD (>1.0 kPa) stem flux reached a plateau in Croton and Podcarpus indicating stomatal limitation.
Changes in plant functional traits and water use in Atlantic rainforest: evidence of conservative water use in spatio-temporal scales

Leaf characteristics, wood anatomy and hydraulic properties in tree species from contrasting habitats within upper Rio Negro forests in the Amazon region

    Journal of Tropical Ecology
  • 2010
TLDR
Leaf blade physical and chemical characteristics, wood composition and anatomy, as well as long-term water-use efficiency and hydraulic characteristics of leaf-bearing terminal branches were assessed in tree species growing in contrasting forests of the Venezuelan Amazonas, suggesting species with more conservative water transport and/or better stomatal control would be at lower risk of mortality.
