“…A relatively large proportion of all known plant species can be designated as clonal or as having complex modularity in the form of potentially autonomous clonal units, i.e., ramets [ 117 ]. Clonality in plants is largely an underevaluated phenomenon with immense theoretical and practical importance [ 118 ]. Physiological integration in clonal plants involves the division of functions and sharing of resources between ramets, allowing for buffering against environmental heterogeneity.…”

The aim of the present review was to reconsider basic information about various functional aspects related to plant water content and provide evidence that the usefulness of measuring absolute water content in plant sciences is undervalued. First, general questions about water status in plants as well as methods for determining water content and their associated problems were discussed. After a brief overview of the structural organization of water in plant tissues, attention was paid to the water content of different parts of plants. Looking at the influence of environmental factors on plant water status, the differences caused by air humidity, mineral supply, biotic effects, salinity, and specific life forms (clonal and succulent plants) were analyzed. Finally, it was concluded that the expression of absolute water content on a dry biomass basis makes easily noticeable functional sense, but the physiological meaning and ecological significance of the drastic differences in plant water content need to be further elucidated.

“…Demographic analysis is an effective approach to understanding the population dynamics and life‐history of organisms (Abrahamson 1980, Silvertown et al 1993, Franklin et al 2021). A basic approach is to determine three fundamental demographic elements of individuals in a population: reproduction, survival and growth.…”

“…However, the mother ramet of newly emerged offspring may not be identifiable from aboveground plant structures, especially in clonal plant species that use underground organs for clonal growth and have long life spans. Ease and required approach of observation largely depend on the architecture of the clonal organs and on expansion frequency (Franklin et al 2021). If the directional connection of mother to daughter is directly observable, exact information about mother–daughter pairs can be obtained and variability in clonal recruitment from mother ramets may be analysed in addition to such demographic traits as survival and growth (e.g.…”

In clonal plant populations, a number of genetically identical ramets form a genet. While coexisting ramets potentially perform independently, their behaviours not only depend on ages and sizes but are also constrained by genetic background. In this study, genet dynamics and its variability among neighbouring genets were investigated based on the ramet demography of each genet in Convallaria keiskei. Genet dynamics were first formulated as a matrix model with the two components of clonal growth (clonal reproduction) and survival‐transitions between ramet size classes. Then, a statistical estimation of the matrix elements was established using three datasets: aboveground demographic censuses, belowground directional rhizome connections and genetic identification of ramets. Finally, genet growth rates reflecting both the changes of clonal growth and ramet size growth were estimated and compared for fundamental demographic elements among genets. Over three years of aboveground annual censuses of a 28 × 2 m plot, 2021 ramets were identified as belonging to 28 genotypes. Belowground excavation detected 515 clonal fragments. Genet growth rate of three dominant genets varied with medians of 1.13, 1.02 and 1.05; 95% credible intervals of the posterior distributions did not overlap between the genet with the largest median and the others. The variation was caused primarily by differences in clonal growth rather than survival‐transitions between size classes. Clonal growth by branching was rarer than at the tips but contributed to the maintenance of the genet. Therefore, both clonal growth frequencies and connecting patterns of ramets caused the variation of genet dynamics and established genets persist for a long time through the positive growth rates, which would contribute to maintain a population. We also conclude that fundamental demographic elements relating to clonal growth traits (the features of individual genets) strongly impact genet dynamics.
