Assisted migration, the human-mediated movement of species and populations, is one adaptive strategy to climate change. Plant phenology affects the survival and distribution of species to local conditions, and its potential modifications need to be explored in the context of assisted migration. We conducted identical experiments in January and April (experiment I and II) and monitored the timing of bud break in sugar maple (<i>Acer saccharum</i> Marshall) under cooling and longer photoperiod to simulate a northward migration. The budbreak in experiment II started 55 days earlier than experiment I. In experiment I, longer photoperiod was more effective than warming in advancing bud break. Compared to experiment II, cooling and long photoperiod had stronger effect in experiment I . Our results demonstrated the significant effect of chilling and confirmed that photoperiod outweighs temperature in initiating bud break when the chilling requirement is unfulfilled. These findings suggest that the future mild winters in the southern range of sugar maple may reduce chilling accumulation and result in the delayed bud break. Sugar maples migrating northward could benefit from longer day lengths, which could partly counteract the delayed effects of colder springs in northern regions, thus ensuring a sufficient growth period.

Abstract Red maple (Acer rubrum L. ‘Franksred’) and sugar maple (Acer saccharum Marsh. ‘Green Mountain’) trees were grown in a 56 liter (15 gal) pot-in-pot system for two years. During the second year of production, root growth was observed through observation plates fitted into the container sidewalls, and shoot extension was periodically measured. Root growth began in early March, approximately one month before budbreak for both species. Root growth dramatically slowed down at the onset of budbreak, but quickly resumed and was concurrent with shoot elongation. Root growth slowed dramatically in the fall when substrate temperatures dropped to 5–7C (40–45F). Root growth stopped during the winter for red maple, but some nominal root growth continued throughout the winter for sugar maple. Red maples had over 5 times more total root length against observation plates at the end of the experiment than sugar maples.

Sugar Maples

Sugar maple (Acer saccharum Marsh.) stands of the Owen Sound and Wingham districts in southwestern Ontario were sampled to assess the importance of cankers caused by Eutypella parasitica Davidson and Lorenz. Stands in the Owen Sound District had Eutypella cankers on 7.4% of the sugar maples. Cankered trees had an average cull loss of 12.4% total cubic volume and 49.2% merchantable cubic volume. The incidence of cankering was significantly less for the Wingham District where maple stands have better overall timber quality than do stands in the Owen Sound District. The incidence of Eutypella canker was a positive function of the percentage content of maple in a stand, maple tree density, and maple tree size. Cull loss due to cankers was related to canker size and tree size and to the position of the canker with respect to log production. Regression models illustrating these relationships are presented.

Abundance of rhizomorphs of Armillaria was characterized in 1995-1996 in 32 plots located in sugar maple (Acer saccharum Marsh.) stands in the Susquehannock State Forest (Pennsylvania, U.S.A.). All of the plots were thinned, and half of the plots were limed in 1985 when the plots were established. Frequency and abundance of Armillaria rhizomorphs in soil samples, on dead wood food bases (stumps, snags, fallen logs), and on the root collar of living sugar maples were determined in each plot. Rhizomorph vigor was evaluated by measuring their ability to colonize fresh striped maple (Acer pennsylvanicum L.) stem sections in the soil, or potato tubers in the laboratory. Isolates of Armillaria were obtained from rhizomorphs in the soil samples and species were determined by somatic incompatibility tests. Armillaria calvescens Bérubé & Dessureault was the major species present, representing about 66% of the isolates. Armillaria gemina Bérubé & Dessureault and Armillaria mellea (Vahl:Fr.) Kummer were also identified in the plots. Frequency of rhizomorphs in the soil, on food bases, abundance of rhizomorphs on root collars, as well as the proportion of rhizomorphs per plot that regenerated and (or) colonized fresh substrates were all correlated. However, abundance of ectotrophic rhizomorphs on the root collar was only weakly correlated with the other components of rhizomorph abundance and vigor. Frequency of the rhizomorphs as well as their ability to colonize fresh substrates were greater in plots either limed or with a high proportion of the basal area in sugar maple prior to thinning. By contrast, abundance of ectotrophic rhizomorphs on root collars was not affected by these factors.

In the 1980s, sugar maple (Acer saccharum Marsh.) dieback was observed across its range in Quebec. In spite of the recovery of the majority of stands during recent years, some have continued to show signs of dieback progression. At the Lake Clair Watershed experimental station, a study was undertaken to evaluate the effect of liming on the nutrition, vigor, and growth of sugar maple in an acid soil, poor in available Ca and Mg. A completely randomized experiment was established and selected sugar maples were treated in 1994 with dolomitic lime in amounts of 0, 0.5, 1, 2, 5, 10, 20, or 50 t·ha-1. Four years after the lime application, improvements in foliar concentrations of N, P, Ca, and Mg were noted. Liming increased the radial growth of sugar maple by 45% for rates from 1 to 10 t·ha-1 and by 90% for rates of 20 t·ha-1, compared with the control trees. The beneficial effects of lime on dieback appeared only very slightly at the third and fourth years after treatment. The negative impact of liming on sugar maple K nutrition could be mitigated by application of potassium sulphate.

Sap flow from the stumps of sugar maples was over five times as great as that from the trunks of the same trees, which were detached in November, January and March. There was no consistent variation in the sugar concentration of sap samples drawn from stumps and trunks, but samples taken from points above girdles were consistently higher in sugar than those taken from below.Sap flow is attributed mainly to the activities of living cells, and it is suggested that the oxygen concentration of the sap and the release of hydrostatic pressure in tapped trees are related to cell activities.The beneficial effect of alternating cold nights and warm days on sap flow is attributed to an increase in availability of oxygen to the living cell through the agency of the relative solubility levels of oxygen in water at low and high temperatures.

Abstract Global changes affect the growing conditions of terrestrial ecosystems, mismatching the phenological adaptation of plants to local climates at mid and high latitudes. Their long lifespan and slow reproductive cycles prevent trees from tracking the quick shift in their usual climatic conditions, thus endangering the survival of local populations. In this study, we explored the phenological plasticity and adaptive potential of bud burst in sugar maple (Acer saccharum Marsh.) seedlings from 30 Canadian origins with contrasting climates planted in two common gardens near and at the northern boundary of the species range. Bud development and leafing occurred in April-May, with complete bud burst lasting between 21 and 29 days. On average, bud swelling differed by 12 days between common gardens. However, this difference decreased to 4 days for complete leafing. Both factors site and seed origin affected bud burst, which represented the phenological plasticity and adaptation of sugar maple, respectively. Overall, the former (7.4–88.3%) contributed more than the latter (9.2–25.5%) to the variance in bud burst, despite the wide climatic range among the provenance origins compared with that at the two common gardens. Adaptation to local conditions provide the genetic tools for the survival of species across wide climatic ranges. Plasticity enables physiological responses of individuals to quick environmental changes. Our study demonstrated the major role of plasticity in bud phenology, and revealed the importance of investing resources in mechanisms dealing with the climatic challenges due to inter-annual variations in weather events.

Selection of sugar maples (Acer saccharum Marsh.) and black maples (Acer saccharum Marsh. ssp. nigrum Desm. or Acer nigrum Michx. f.) that will be more resilient than existing cultivars in managed landscapes could be facilitated by defining relationships between geographic origin and foliar traits critical to leaf function. We examined variation in leaf morphology and anatomy of both taxa, known collectively as hard maples, near 43 °N latitude and tested for relationships between foliar traits and the longitude of origin from 70 ° to 94 °W longitude. Leaves exposed to direct solar radiation were sampled from up to 20 trees indigenous at each of 42 sites during 1995 and 1996. All leaves from east of 75.84 °W and from 92.73 °W and further west expressed morphological characters associated with sugar maple and black maple, respectively; leaves with intermediate traits were found between these two longitudes. Leaves from 90 ° to 94 °W had the highest surface area due to increases in the areas of middle and proximal portions of laminae. Up to 1162 trichomes/cm2 were present on the abaxial surface of laminae from west of 85 °W, while laminae from further east were glabrous or had ≤300 trichomes/cm2. Laminae from western habitats also had relatively high stomatal frequency, and stomatal apertures of laminae west of 91 °W were particularly narrow. Longitude did not affect specific weight and thickness of laminae, which averaged 5.5 mg·cm-2 and 90 μm, respectively. Principal component analysis of laminar traits showed existence of two clusters. A large group dominated by data from trees in New England also contained data from trees as far west as ≈93 °W longitude; data for trees further west were clustered separately. Although phenotypic continua were defined, laminae west of 93 °W were distinct, which suggests trees selected there may function differently in managed landscapes than trees selected from native populations further east.

Early Fall

In 1983, a trial was initiated to compare numerous selections of sugar maple (Acer saccharum) for adaptability to stressful conditions in south central Kansas (zone 6). Included were seedlings of Caddo maple, a southern ecotype, collected from a population native to central Oklahoma. Selected trees have shown superior resistance to scorch and leaf tatter compared to cultivars in the trade. Pre-dawn measurements indicated higher xylem water potential than `Green Mountain' and `Fairview' under drought stress. Leaf emergence of Caddo maples has been earlier in the spring, and fall color develops later than other sugar maples. Propagation of potential cultivars with early fall color has been principally by T-budding on Caddo understock in July and August, although side-veneer grafting in winter has been successful. In addition to superior summer leaf quality, growth in caliper and total height has been greater than other A. saccharum cultivars.

Species with wide geographical ranges exhibit specific adaptations to local climates, which may result in diverging responses among populations to changing conditions. Climate change has advanced spring phenology worldwide, but questions of whether and how the phenological responses to warming differ among individuals across the natural range of a species remain. We conducted two experiments in January and April 2019, and performed daily observations of the timings of bud break in 1-year-old seedlings of sugar maple (Acer saccharum Marshall) from 25 Canadian provenances at two thermal conditions (14/10 and 18/14 °C day/night temperature) in a controlled environment. Overall, bud break started 6 days from the beginning of the experiments and finished after 125 days. The earlier events were observed in seedlings originating from the colder sites. Bud break was delayed by 4.8 days per additional degree Celsius in the mean annual temperature at the origin site. Warming advanced the timing of bud break by 17–27 days in January and by 3–8 days in April. Similar advancements in bud break were observed among provenances under warming conditions, which rejected our hypothesis that sugar maple populations have different phenological responses to warming. Our findings confirm the differentiation in ecotypes for the process of bud break in sugar maple. In cases of homogenous spring warming across the native range of sugar maple, similar advancements in bud phenology can be expected in different populations.

Abstract Acer saccharum and Acer rubrum, two main maple species in North America, will be affected by ongoing global warming. Several studies predict a southern limit contraction but limited northward expansion of maple distribution for the future. We aimed to understand the main drivers of current maple distribution to quantify potential changes to maple habitat in this context. We identified the local conditions of maple stands and assessed the potential changes under warming scenarios. We selected two regions in Quebec, Canada, at the northern distribution of the species and applied probability distribution function and principal component analysis to identify the factors explaining the occurrence of maple compared with other forest species, croplands, and grasslands. Maple habitat was estimated under warming scenarios up to 2°C. We observed a lower density of maple stands in the north (7.76 %), compared to the south (33.01 %). Warming increased maple stands by 3.54 and 1.45 % in the northernmost and southernmost regions, respectively, with the highest increases being estimated at the initial warming (+1.0°C). We conclude that maple of northern regions can benefit from local warming if precipitation does not become limiting. These changes could increase the potential for the regional maple industry and forest management. Study Implications Future warming may enhance the opportunities to exploit maple and its products at the northern boundary of this species, under a sufficient precipitation regime. Plantations could be considered in habitats favorable for maple, which would allow the value of the resource at the northern edge of the temperate mixedwood forest to be increased. Our spatially explicit outcomes will encourage forest managers and small landowners to plan new maple plantations. The local maple industry and forest management in northern regions could benefit from such an increase in maple habitat and enhanced production of hardwood species.
