Temperature Regimes

Hyperbolic temperature exposures (in which the rate of temperature rise increases with time) and an analytical solution to a rate-process model were used to characterise the impairment of respiration in samples containing both phloem (live bark) and vascular-cambium tissue during exposures to temperatures such as those experienced by the vascular cambium in tree stems heated by forest fires. Tissue impairment was characterised for red maple (Acer rubrum), chestnut oak (Quercus prinus), Douglas fir (Pseudotsuga menziesii), and ponderosa pine (Pinus ponderosa) samples. The estimated temperature dependence of the model’s rate parameter (described by the Arrhenius equation) was a function of the temperature regime to which tissues were exposed. Temperatures rising hyperbolically from near ambient (30°C) to 65°C produced rate parameters for the deciduous species that were similar at 60°C to those from the literature, estimated by using fixed temperature exposures. In contrast, samples from all species showed low rates of impairment, conifer samples more so than deciduous, after exposure to regimes in which temperatures rose hyperbolically between 50 and 60°C. A hypersensitive response could explain an early lag in tissue-impairment rates that apparently caused the differences among heating regimes. A simulation based on stem vascular-cambium temperature regimes measured during fires shows how temperature-dependent impairment rates can be used to predict tissue necrosis in fires. To our knowledge, hyperbolic temperature exposures have not been used to characterise plant tissue thermal tolerance and, given certain caveats, could provide more realistic data more efficiently than fixed-temperature exposures.

Fluorescence microscopy was used to show that during 34 days after the wounding of red maple, Acer rubrum, callose accumulated in the phloem, new xylary tissues formed, and plugs formed in vessels to 10 cm above and below the wounds.

Soils collected from eight different plant communities that contained red maples (Acer rubrum L.) had little effect on root fan structures of red maple seedlings. Seedlings from eight seed sources, grown in the same soil types, showed a significant amount of variation for third order root characteristics. Root fan structures, especially those characteristics relating to beaded rootlets, were significantly affected by soil sterilization. Root fan structures were more copious and developed more rapidly on indigenous seedlings than on seedlings grown under greenhouse conditions.

Abstract Four experiments were conducted to investigate herbicides currently labeled for field and/or container production for use in pot-in-pot production. Southern magnolia (Magnolia grandiflora L.), red maple (Acer rubrum Spach. ‘Autumn Flame’ and ‘Franksred’), ornamental pear (Pyrus calleryana Decne. ‘Bradford’ and ‘Cleveland Select’), river birch (Betula nigra L.), green ash (Fraxinus pennsylvanica Marsh. and F. pennsylvanica Marsh.‘Marshall's Seedless’), and zelkova (Zelkova serrata Spach ‘Village Green’) were evaluated for herbicide tolerance. Barricade 65WG, Surflan 4AS, and Pendulum 60WDG, used alone or in combination with Princep and Gallery 75 DF, had no adverse effect on tree shoot growth or trunk caliper growth when applied as a directed band application. Weed control varied depending upon local site conditions, herbicide rate and weed species.

Abstract Two experiments were conducted to determine whether genotypes of red maple (Acer rubrum L.) and Freeman maple (A. x freemanii E. Murray) differ in responses to high root-zone temperature. During the first experiment, dry mass of ‘Franksred’, ‘October Glory’, and ‘Schlesinger’ red maple, ‘Indian Summer’ Freeman maple, and selections from Arkansas, Maine, and Wisconsin were similar at 24, 28, and 32C (75, 82, and 90F), but dry mass at 36C (97F) was only 22% of that at 28C (82F). ‘Autumn Flame’, ‘Franksred’, ‘October Glory’, and ‘Schlesinger’ red maple and ‘Indian Summer’ and ‘Jeffersred’ Freeman maple differed in responses to 34C (93F) during the second experiment. Stem length and plant dry mass were higher at 28C (82F) than at 34C (93F) for all cultivars except ‘Autumn Flame’ and ‘Jeffersred’, and the extent to which 34C (93F) decreased the length of the longest third-order root ranged from 50% for ‘Autumn Flame’ to 90% for ‘Indian Summer’. The higher root-zone temperature decreased transpiration by as little as 25% for ‘Jeffersred’ to as much as 89% for ‘Franksred’, and 34C (93F) reduced leaf chlorophyll content of only ‘Indian Summer’ and ‘Jeffersred’. These results indicate that ‘Franksred’ and ‘Indian Summer’ are relatively sensitive while ‘Autumn Flame’, ‘Jeffersred’, and ‘Schlesinger’ are relatively resistant to high root-zone temperature.

Fertilizer Regimes

Landscape trees typically grow slowly for several years after transplanting. We investigated whether fertilization could speed tree growth during this establishment period, which fertilization regimes were most effective, and whether fertilization interacted with irrigation. Fifty-four each of landscape-sized, balled-and-burlapped red maple (Acer rubrum) and littleleaf linden (Tilia cordata) were planted into a relatively infertile silt loam soil and were fertilized (1.5 kg N/100 m 2[3 lb N/1000 ft 2]) each spring (either including or not including at planting), each fall, or not fertilized. Each of these fertilizer regimes was either irrigated or not irrigated during 3 years. An additional treatment of an unirrigated, split (spring/fall) fertilizer application was included. There was no evidence that fertilization affected irrigated trees differently than unirrigated trees. Overall, fertilization did not speed establishment and did not affect trunk growth, shoot extension, or leaf nitrogen content. There was no evidence that fall fertilization might be more effective than spring fertilization. There was no indication that fertilized trees experienced increased drought stress. Nitrogen rates and factors affecting fertilizer uptake are discussed.
