Dynamic morphological plasticity in response to emergence timing in Abutilon theophrasti (Malvaceae)
<p>Selections on emergence time might be conflicting, suggesting the existence of the optimal emergence time for plants. However, we know little about this and how morphological plasticity contributes to the strategies of plants in response to emergence timing. To better understand this issue in a dynamic perspective, we conducted a field experiment by subjecting plants of <em>Abutilon theophrasti</em> to four emergence treatments (ET1~ET4) and measuring a number of mass and morphological traits on them at different growth stages (I~IV). At day 50, 70 and/or final harvest, among all ET treatments, plants germinated in late spring (ET2) performed the best in total mass, spring germinants (ET1) and ET2 performed better in stem allocation, stem and root diameters than later germinants (ET3 and ET4); summer germinants (ET3) had the highest reproductive mass and allocation, while late-summer germinants (ET4) had the greatest leaf mass allocation, with greater or canalized leaf number and root length traits than others. Plants that emerged in late spring can maximize their growth potential, while those with either advanced or delayed emergence are still capable of adaptation via allocation and morphological plasticity. Early germinants (ET1 and ET2) preferred stem growth to leaf and reproductive growth, due to sufficient time for reproduction in growth season. With limited time for growth, plants emerged late may prefer to quicken leaf growth (indicated by increased leaf mass allocation and leaf number) at the cost of stem or root growth for complete life cycle, reflecting both positive and negative effects of delayed emergence.</p>
Architectural plasticity in response to population density in Abutilon theophrasti (Malvaceae)
<p><strong><span>Background and Aims</span></strong><em> </em>An increase of population density may result in the spatial and temporal heterogeneity of resources at minor scales than an individual, inducing different modular responses at different positions of a plant, or architectural plasticity. To better understanding how plants respond to density via plasticity in architecture, we conducted a field experiment with an annual species of <em><span>Abutilon theophrasti</span></em>.</p> <p><strong><span>Key Results </span></strong>Increased density had different effects for different layers of modular traits, and effects also varied with different stages; high density also reduced variations among layers in different traits. No variation due to density or among different layers was found in reproductive mass and branch traits.</p> <p><strong><span>Conclusions</span></strong><em> </em>An increase of density can induce contrasting responses in different layers of a trait and in different traits of a module, indicating trade-offs between layers and between traits, and low to intermediate competition strength was more likely to induce active response in more layers. It suggested that plants are able to deal with competition via several strategies simultaneously, producing an integrated phenotype. These conclusions further contributed to the complexity of plant plasticity to density.</p>

Figure 2 in Effect of degree of water stress on growth and fecundity of velvetleaf (Abutilon theophrOsti) using soil moisture sensors
Figure 2. Effect of degree of water stress on (A) leaves per plant, (B) plant height, and (C) growth index of Abutilon threophrasti after 84 d after transplanting (DATr) during both years. The 100%, 75%, 50%, and 25% field capacity (FC) treatments correspond to no, light, moderate, and high water stress, respectively. Only one A. threophrasti plant maintained at 25% FC survived more than 77 DATr during both years, and the three-parameter log-logistic model did not provide a good fit for leaves per plant, plant height, or growth index; therefore, curves are presented for 25% FC, although only for visual reference.
