“…Similar axes of variations among growth forms may also be found within a single plant species across environmental gradients (Hajek et al 2013, Isaac et al 2017, Wang et al 2021, Westerband et al 2021) and/or with ontogeny (Houter and Pons 2012, Mason et al 2013, Mediavilla et al 2014). Here again, variations of plant trait with ontogeny were also more investigated in terms of leaf/aboveground traits, whereas ontogenetic variations of root traits remains particularly limited (Alvarez‐Flores et al 2014, Garbowski et al 2021).…”

Heteroblastic variations among leaf traits is a well‐known process, especially in bromeliad species that show abrupt changes, but little effort was directed to test whether comparable ontogenetic variation occurs among root traits and their fungal partners. Usually considered for their mechanical role, roots of bromeliads may also play a role in resource use that we expect to differ between ontogenetic stages, namely nutrient pulse‐supplied atmospherics (young stage) and continuously‐supplied tanks (later stage). On a selection of adventitious roots of the heteroblastic epiphyte Lutheria splendens, we explored 1) ontogenetic variations in morphological and anatomical root traits, namely the number of adventitious roots and tips, total root length, average root diameter, root tissue density, specific root length and root tissue areas, and 2) ontogenetic changes in the composition of the root‐associated fungal communities using ITS1 region‐based high‐throughput sequencing. Plant size, taken as an indicator of gradual ontogenetic variations, and plant stage had significant effects on root traits, unless for root tissue density. The number of adventitious roots and tips, the total root length, average root diameter and all root tissue areas (i.e. velamen, outer cortex, inner cortex, vascular cylinder) increased gradually with ontogeny while the specific root length decreased abruptly. The root‐associated fungal communities varied with plant stage. The tank stage showed higher proportion of mycorrhizal fungi and a lower abundance of dark septate endophyte as compared to atmospheric stage. Overall, we demonstrated significant ontogenetic variations of root traits and fungal partners in bromeliad species that suggest important changes in the strategy for resource use as plants mature. We invite future root trait studies to better account for ontogenetic variations.

“…For example, we only had leaf vein traits and lacked leaf stomatal traits in mangrove plants. Nevertheless, incomplete mangrove leaf hydraulic traits could hardly markedly affect the relationships between leaf hydraulics and leaf economics and root hydraulics because of the universal coupling between leaf vein and stomatal traits 50,51,52,53,54 .…”

Interactions among root and leaf traits (in particular, leaf hydraulic and leaf economics traits) are fundamental in generating diverse strategies in land plants, yet it remains a knowledge gap in mangrove plants that experiences saline stress distinct from most other vascular plants. Here, we tested the trait relationships in mangrove plants and compared them with typical land plants (non-mangrove). Consistent with non-mangrove plants, leaf hydraulic and economics traits were decoupled in mangrove plants. However, mangrove leaf economics traits correlated strongly with root hydraulic traits, which are normally decoupled in non-mangrove plants. Moreover, we observed a unique scaling relationship between leaf dry mass per area and root hydraulic traits in mangroves. The novel coordination between leaves and roots arises from the wide-presence of leaf water storage tissues in mangroves, and this potentially represents a new paradigm with which we look into the ecology, physiology and evolution of this important vegetation.

“…Leigh et al [4] further confirmed this result by finding that the leaf vein density, stomatal density, and tracheid numbers in G. biloba were highly heterogeneous among positions. Unfortunately, many studies on the leaf anatomy of G. biloba still focus on a single region [16][17][18]. Notably, G. biloba has distinctive fan-shaped leaves with an open dichotomous venation pattern.…”

Ginkgo biloba is a dioecious heterophyllous tree species with two leaf types. Short shoots always bear many leaves, which are undivided or slightly bilobed, but long-shoot leaves are smaller and are deeply divided into two or more lobes. To clarify the functional difference between the two leaf types, we investigated the morphology, anatomy, gas exchange, and hydraulic traits of the two leaf types in male and female trees. Our results showed that long-shoot leaves possessed a lower specific leaf area (SLA), higher leaf thickness, gas exchange rates, and average tracheid number than short-shoot leaves. When compared to short-shoot leaves, long-shoot leaves in male trees had higher leaf hydraulic conductance (Kleaf) and leaf water potential of 50% loss in Kleaf (leaf P50), while female trees exhibited relatively higher Kleaf. When comparing sexual differences, male trees possessed higher leaf thickness, leaf dissection index, vein density (VD), and predawn leaf water potential and lower SLA, tracheid number, and midday leaf water potential, while no significant difference in leaf P50 was observed between the two sexes. Male trees exhibited greater leaf gas exchange rates, which were tightly associated with other functional traits, such as VD and Kleaf. We found strong shoot-based and sex-related heterogeneities in the leaf hydrology, anatomy, and economy of Ginkgo biloba. Moreover, male ginkgoes may perform better due to their greater leaf hydraulic efficiency and gas exchange rates.
