In order to assess the effects of ambient levels of ozone and acid rain on drought-stressed trees, one-yr-old containerized seedlings of yellow poplar (Liriodendron tulipifera) from a nursery at Zanesville, Ohio, USA, were exposed to simulated acid rain (pH, ), ozone (O3) fumigation (0, p.p.m.), and drought (1, 2, or 3 one-wk drying cycles) from late Cited by: Growth and physiological responses of yellow-poplar seedlings exposed to ozone and simulated acidic rain.

Liriodendron tulipifera—known as the tulip tree, American tulip tree, tulipwood, tuliptree, tulip poplar, whitewood, fiddletree, and yellow-poplar—is the North American representative of the two-species genus Liriodendron (the other member is Liriodendron chinense), and the tallest eastern is native to eastern North America from Southern Ontario and possibly southern Clade: Tracheophytes.

Oak regeneration failures have been causing a slow decline in the occurrence of oak forest ecosystems in eastern North America. Accordingly, our study sought to determine a means of creating more vigorous and competitive oak seedlings by the addition of manganese (Mn) fertilizers.

Middle-aged Tuliptree. Tuliptree1 Edward F. Gilman and Dennis G. Watson2 INTRODUCTION Tuliptree grows 80 to feet tall and maintains a fairly narrow oval crown, even as it grows older (Fig.

Trunks become massive in old age, becoming deeply furrowed with thick bark. The tree maintains aFile Size: KB. ¥ Drought-tolerant plants usually have thick leaf waxes and bark, efficient stomatal control and ext-ensive root systems.

Examples of a few trees that are not drought-tolerant include black cherry, dogwood, yellow-poplar, basswood, birch, buckeye and sycamore. These species respond to drought by shedding their leaves prematurely or Size: KB. A shift in species distribution associated with global climate change may be dependent on the response of seedlings to extreme stress events.

Seedlings of Eucalyptus macrorhyncha and E. rossii were grown for 8 weeks in either ambient ( ppm) or elevated ( ppm) CO{sub 2} concentrations and either well watered or without water additions and subjected to a daily, 3 h.

Three major hypotheses were tested: 1) C02 enrichment ameliorates the negative effect~ of 03; 2) the relative response to 03 and C02 is the same in short-term studies with seedlings as with older trees; and 3) faster growing hardwood species are more sensitive to 03 and more responsive to elevated C02 than slower growing conifer species.

A field study at the Smithsonian Environmental Research Center in Maryland found wine raspberry ramets and seedlings occurred more frequently in 2-year-old, storm-created gaps than in random plots in year-old ("old") forest dominated by yellow-poplar, oak, hickory, American beech, and sweetgum and year-old ("young") forest dominated by.

cesses. Water contents in a tree under drought conditions disrupt life processes. Trees have developed a series of prioritized strategies for reacting to drought conditions (listed in order from least damaging to most damaging response): 1) recognizing (“sensing”) soil / root water availability problems.

Global atmospheric carbon dioxide (CO{sub 2}) concentrations are continuing to increase and will probably double during the next century. The effects of such an increase are of global concern.

Carbon dioxide-induced climate changes may result in. The potential interactions among abiotic and biotic factors in southern pine forests are extremely complex, particularly when one considers these interactions over a tree’s lifetime.

We know from experimental data that individual factors tend to impact trees either negatively or positively: Only factors that show a response tend to be by: 4.
