“…The number of floristic zones occupied by short-lived rootsprouters is higher than the number of zones occupied by short-lived plants without root-sprouting ability, however their ecological niche is narrower. The ecological niche of short-lived root-sprouting species is restricted to places with certain affection by human activity, supposedly a specific disturbance regime causing plant injury during the vegetative season (Malíková et al 2010). …”

“…Short-lived species represent a clearly defined group of plant species comprising those with and without multiple strategies of regeneration. Multiple regenerative strategies in the short-lived species represent a co-occurrence of i) generative regeneration from a seed bank and ii) vegetative regeneration by adventitious sprouting from roots and/or hypocotyle (Klimešová 2003;Martínková et al 2004aMartínková et al ,b, 2008Klimešová and Klimeš 2007;Klimešová et al 2008;Malíková et al 2010). In short-lived species, adventitious sprouting from roots plays a key role especially in disturbed habitats ( Fig.…”

It is expected that plant species with multiple regenerative strategies have a wider ecological amplitude and geographical distribution. However there is still an anxious question why species with multiple regenerative strategies are not more frequent.In the presented work we asked whether short-lived plants with a potential bud bank i) have a wider geographical distribution, ii) occur more frequently in human-made habitats and iii) more frequently possess invasive status in comparison with the shortlived species without this additional regenerative strategy. Results show that short-lived plants with a potential bud bank are i) more widely geographically distributed, ii) under-represented in natural habitats and weakly over-represented in habitats disturbed by human activities and iii) contrary to expectation, less numerous among neophytes than species without a potential bud bank. This suggests that short-lived root-sprouters are more habitat-specialized when compared with such plants without adventitious bud-bank formation, but are more widely geographically distributed. A higher frequency of multiple regeneration strategies seems to be restricted by costs of having this ability in habitats or situations without a disturbance regime.

“…Good examples are serotiny or lignotubers in flammable ecosystems (Bellingham and Sparrow 2000;Bell 2001). Another trait that has been studied intensively in recent years is the ability to form adventitious buds on roots (Klimešová and Martínková 2004;Malíková et al 2010). Plants carrying this trait have a potential bud bank that gets initiated after injury to overcome meristem limitation after severe damage and to facilitate regeneration .…”

Root sprouting in Knautia arvensis (Dipsacaceae): effects of polyploidy, soil origin and nutrient availability

et al. 2015

Plants able to resprout from roots have a potential bud bank that gets initiated after injury to overcome meristem limitation after loss of all stem parts and to facilitate regeneration. Knautia arvensis is reportedly able to sprout from its roots on arable land, but information is missing regarding such ability in serpentine populations or how it might differ between diploids and tetraploids. We hypothesized that (1) 'ruderal' non-serpentine populations better tolerate severe disturbance than relic, serpentine ones; (2) tetraploid populations resprout more readily than diploids due to enhanced growth of higher ploidy levels; and (3) plants of different ploidy levels from serpentine soils are, for evolutionary reasons, more similar in their response to disturbances than plants from non-serpentine soils. To test these hypotheses, we conducted a pot experiment. Its results do not support our hypothesis that the ability to sprout from roots is a factor driving the spread of new weedy taxa into central Europe or the hypothesis that it is related to polyploidization in the genus Knautia. Both tetraploids and plants from non-serpentine populations regenerated less vigorously than diploids and plants from serpentine populations. However, the genetically closer populations of serpentine origin were more similar in their response to experimental manipulations than their genetically distinct non-serpentine counterparts. The success of non-serpentine taxa in disturbed habitats of central Europe might be related to traits other than the ability to resprout.

“…The bud bank is formed de novo on otherwise meristemless organs, such as roots or hypocotyls, and may enable vegetative regeneration after very severe disturbance that results in the loss of some or all aboveground organs. This ability is found in 13% of biennial and 2% of annual species of central Europe (Klimešová and Klimeš 2003;Malíková et al 2010).…”

Tolerance to very severe disturbance by the annual herb Euphorbia peplus L. was examined. We explored the role of disturbance timing, competition, and site productivity on the performance of disturbed plants. Ninety-three percent of disturbed plants survived following disturbance 14 d after plant emergence, whereas only 48% of disturbed plants survived disturbance 42 d after emergence. Early disturbed plants compensated for biomass loss and had higher fecundity than undisturbed plants, but this was not the case for plants that were disturbed at later times following emergence. Field assessment revealed that disturbed plants were, in general, of the same height as undisturbed plants, even under competition. Undisturbed plants had very conservative architecture across various conditions (competition and nutrients), whereas disturbed plants had more branched architecture under moderate competition and nutrient availability. Accordingly, we suggest that E. peplus utilizes a bet-hedging strategy where adventitious meristems are reserved for regrowth after a severe disturbance event that removes all dormant axillary meristems. Moreover, we propose that the tolerance to disturbance in short-lived species could play an important role in the ecology of disturbed communities. Finally, the tolerance to disturbance could be one of the prerequisites of invasibility of E. peplus in non-native ranges. We also speculate about the potential costs and benefits related with the tolerance to disturbance in short-lived species and about a mechanical control of E. peplus in invaded ranges.Résumé : Les auteurs ont examiné la tolérance aux perturbations sévères chez l'herbacée annuelle Euphorbia peplus. Ils ont exploré le rôle du moment de la perturbation, de la compétition, et de la productivité du site sur la performance des plantes dérangées. Quatre-vingt-treize pour cent des plantes dérangées survivent à une perturbation survenant 14 jours après l'émer-gence, alors que seulement 48% des plantes dérangées survivent à une perturbation survenant 42 jours après l'émergence. Les plantes dérangées précocement compensent la biomasse perdue et montrent une meilleure fécondité que les plantes non perturbées, mais ceci n'est pas le cas chez les plantes dérangées plus tard après leur émergence. Les données prises sur le terrain révèlent que les plantes perturbées sont, en général, de la même hauteur que les plantes non perturbées, même sous l'effet de la compétition. Les plantes non perturbées montrent une architecture conservatrice sous diverses conditions (compétition et nutriments) alors que les plantes dérangées exhibent une architecture plus ramifiée sous une compétition et une disponibilité des nutriments modérées. Conséquemment, les auteurs suggèrent que l'E. peplus utilise une stratégie de plasticité développementale où des méristèmes adventifs sont réservés à une reprise de croissance, suite à une perturbation sévère, même celle conduisant à la perte de tous les bourgeons axillaires dormants. De plus, les auteurs proposent que la tolé...

Occurrence of adventitious sprouting in short-lived monocarpic herbs: a field study of 22 weedy species

Abstract: Adventitious bud formation is used to overcome meristem limitation when stem parts are lost due to injury, and thus resprouting in short-lived monocarps should not be overlooked.
